Wiper Motor Refurbishment & Intermittent Controller

Wiper Motor

The wiper motor, as taken from the car, turned out to be pretty dirty and it did not operate.

Rotating Arm & Gear

Time for a clean-up

It appears to be the original motor as the casing has a stamped production date of 12/1958, so just before the car came off the assembly line. We disassembled the motor, gave it a good cleaning, lubricating and painting and after hooking it up to a power source we judged it to be operational and good for continued use in the Bugeye!

Video Episode Forty-one details the motor refurbishment process:


The motor is only one speed – slow. The same wiper motor was used in the Big Healey and we decided to add the same intermittent speed controller that my Dad incorporated in  the 3000. It doesn’t make the motor any faster, but it does greatly improve the operation of the wipers in misty conditions.

Intermittent Wiper Control

Ed Esslinger authored an article on a Sunbeam Tiger web site about a kit he put together to provide unlimited variable control of the speed of the Lucas wiper motor. We will probably install the control knob for the variable speed rheostat on the vertical panel that will be created later to fit between the dash and the gearbox tunnel.  The controller electronics will be hid behind the panel. The kit can even be wired to accommodate most state laws that now require your lights to be on when the wipers are functioning! The lights come on automatically. This is the instruction sheet: Wiper Control and a wiring diagram:

Exterior Lighting

This post covers the restoration and/or replacement of the lighting fixtures of the Bugeye Sprite. The image below taken from the Sprite Service Parts List illustrates the components of the car’s lighting system:

Bugeye Lighting

The Bugeye Restoration Video Episode Forty (link below) covers our restoration efforts. Where parts were perished, such as rubber seals, they were replaced with new items. However, some original parts were cleaned and repainted to continue their service.

Headlight bowl and mounting ring

Light bulbs in the flashers (turn signals) were replaced with LED units. These are much brighter, consume lower amperage, and produce less heat. This requires replacing the flasher relay can with a substitute suited for LEDs. The headlights currently on the car are Wagner sealed beam halogen bulbs and we will continue to use these. The bulbs in the number plate lamp are incandescent units and we will also continue to use these.

The headlight chrome rims are secured to the headlight bowl with a clip and screw as seen below:

Headlight Trim ring securing screw clip

These screws can be a challenge to mount. MGBs used a spring clip instead of the screw clip. We substituted these spring tension clips and hopefully they will work well. We can always go back to the original approach.

With all of the parts refurbished and accumulated we are now ready for installation at a later date.

Bonnet Wiring Harness and Lights Removal

My car has been modified to convert the bonnet from the original hinge at the rear, opening from the front, to a front hinge opening at the rear. This is a common modification and it does offer much greater and easier access to the engine and other under-bonnet components. I want to be able to quickly and completely remove the bonnet from the car if the need arises and this means that the wiring harness that services the electrical needs of the front of the car must provide for an electrical connector joining the primary system to the bonnet.

The bonnet includes the LH and RH combined side and flasher lights, the LH and RH main beam headlight, and the LH and RH high beam headlight.

Electrical System Deconstruction

We will be completely replacing the wiring in the Bugeye with new materials including a new relay/fuse panel sourced from Classic Technologies. Before we can give attention to the “new” going in, the “old” must come out. Just to help with resolving any wiring issues later, we will be disciplined in the removal with video and written documentation of how things are installed. What is coming out of the car is not original, in fact, it is not even a professionally produced harness. The previous owner built his own harness which while not very elegant did seem to function effectively.

There is quite a lot of work involved in removing and documenting and the process took several days. The links for a three-part video series are provided below along with a sequential index of video content for each.

Front Suspension, Brakes and Steering Completed

It has been a little more than three months since we began the work on the front suspension, brakes and steering in the Bugeye, but we have now completed the rebuild and have the car back on its tires and on the ground!

Everything has been updated and documented in previous posts in this blog:

New hub bearings and seals

New king pins and bushings in the spindle axles

New rotors, calipers and brake pads, new Goodridge stainless brake hoses, new cunifer hard brake pipes, new “Sebring-type” pedal box and pedal pads with separate master cylinders

New “A” arms, fulcrum pins and poly bushes throughout

New steering rack, shims and rod ends and the proper steering arms were sourced and installed

Rebuilt lever shocks and new rubber bump stops

New coil springs

Everything cleaned and painted

The Bugeye Restoration Episode Thirty-five video shows the final steps in completing the work described above. 


The following steps are addressed in the video:

0:00 – Torquing the hub nuts and installing split pins

0:44 – Hub grease caps installed

0:48 – Front caliper banjo bolts installed

1:20 – Goodridge Stainless Steel flexible brake hoses installed

1:35 – Making brake pipe bubble flares

4:42 – Master cylinder to brake union brake pipe installed

5:00 – Steering rack installed

5:52 – Steering rack bracket shims installed

6:14 – Steering column to steering rack pinion shaft mating

6:50 – Steering rack mounting clamp bolts torqued

7:17 – Tie rod ends fitted and torqued

7:30 – Toe-in adjustment

7:50 – Front tires mounted and car placed back on the ground

9:12 – Inner fulcrum pins tightened




Rebuilt Front Suspension Installed in the Car

It seems that we have been working on rebuilding and installing the front suspension for a very long time, but in this post the suspension and front brake components are finally reinstalled in the car.

We attached the lower “A” arm to the hub assembly. This involves positioning the king pin between two cork washers and screwing the fulcrum pin into the “A” arm the outer bushing, through the king pin and into the other side of the “A” arm.

Screwing fulcrum pin into “A” arm and king pin

The fulcrum pin needs to be centered in the king pin with the concave curve in the pin open such that the cotter pin (with one flat side) can be inserted into the king pin and pushed through the fulcrum pin so that a nut can be attached to the lower end of the cotter pin. This process is covered in the attached video.

Cotter pin in place

After going through that process we discovered that the steel bushes in the used “A” arms were completely knackered with way too much play and we had to order a new pair. The “a” arms are available from British Heritage and are supposed to be as original, however, they are very expensive. A lower priced aftermarket “A” arm, produced in the UK, is also available and contributors to the on-line Sprite Forum reported that these units are satisfactory. So, we ordered a pair of these from AH Spares and repeated the process of mounting the hub assembly to the “A” arm!

After market “A” arm and new coils spring

One side of the “A” arm outer bushing was already capped, but the other side required a screwed plug and grease zerk to be screwed into place.

“A” arm grease zerk fitting

The next step was to install the hub assembly and “A” arm (wishbone) to the car. While supporting  the weight of the hub assembly on a floor jack, the assembly was secured to the damper arm with the top fulcrum pin.

Supporting hub assembly to insert uppertrunbnion fulcrum pin

Like the lower pin, there is a concave spot on the shaft of the bolt through which the damper pinch bolt must align in order for the pinch bolt to screw into the damper arm. The top fulcrum pin is inserted from the rear through a new rear poly bush, pushed through the upper trunnion, and then through the front poly bushing before passing through the damper arm where it is then secured with a castle nut and split pin.

Upper Trunnion bolt washers and poly bushes

Upper Hub Assembling Mounting


The Upper Trunnion sits atop a thrust washer on the swivel axle. Two small shims are placed on the king pin below the thrust washer and upper trunnion before they are placed on the top of the king pin. After the upper trunnion is in place a nylock nut is used to tighten the swivel axle assembly. At this point we have the hub assembly secured at its top. We did not tighten the upper trunnion until after we mounted the lower “A” arm to the car.

New poly bushes were mounted on either side of the inside of the “A” arm and using a combination of a floor jack and a bottle jack the inside of the “A” arm was pushed into place so the the inner fulcrum pins could be pushed through and secured with nylock nuts. These won’t be tightened until we have the weight of the car on the ground.

With everything mounted properly it was time to tighten nuts and bolts. The top trunnion nut was torqued to 40 ft. lbs. If the rotation of the hub (front to back) is too tight a shim is added, if there is too much play a shim is removed.

We then tightened the two bolts that secure the caliper to the swivel axle. These are tightened to 46 ft. lbs. The tab washers under the bolt heads will be turned up at a later date. The steering arm bolts were torqued to 39 ft. lbs. The tab washers under the bolt heads will be turned up at a later date. Finally, the three mounting bolts on each damper were torqued to 27 ft. lbs.

Everything buttoned up

The next step was to install the front coil springs. The spring seats, or pans, were removed  from the “A” arm. The spring was then placed on the spring seat and pushed upward through the “A” arm wishbone. Compressed springs can be very dangerous and consequently we choose to use long threaded rods to safely compress the springs.

We prepared four 5/16″ – 18 “all-thread” rods by cutting each to six inch lengths. Double nuts were placed on the top of the rods and tightened against one another. Coupling nuts were used on the top and bottom to make the nuts more accessible to turn with a wrench. Flat washers were also used between the spring seat and the nuts.

The nuts were gradually tightened until the spring was compressed and the spring seat was tight against the “A” arm. Then, one at a time, the long rods were loosened and replaced with 5/16″-24 x 3/4″ hex head bolts and nylock nuts.

Coil spring installed

1 1/8″ wooden spacer block to simulate normal hub height

We will still need to bend back tab washers, lubricate the grease zerks and tighten the inner “A” arm fulcrum pins, tighten the hub nut and insert its split pin and install the grease caps. But, these are all little steps to be accomplished later. The big stuff is done.

Bugeye Restoration Video Episode Thirty-four addresses the joining of the hub assembly with the lower “A” arm (wishbone) and the the installation of the combined assembly to the car.


The following steps are addressed in the video:

0:00 – Lower “A” arm installed to king pin and swivel axle

1:18 – Outer fulcrum pin, cotter pin and grease fitting installed

2:29 – Excessive play discovered in old “A” arms

4:00 – Lower coil spring pans installed in “A”arms

4:30 – Hub assembly and “A” arms installed in car

5:00 – Poly bushes installed in inner “A” arm and then to car

5:53 – Damper pinch bolt and upper fulcrum pin

6:52 – Torqueing the caliper, steering arms, and damper bolts

7:24 – Coil spring installation with “all-thread” rods


Front Brakes, Pedal Box and Steering Rack

Brake Pipes – Sometimes as one proceeds with working on the major systems of the car parts just get in the way! We are installing the modified Sebring-style pedal box with separate Girling master cylinders and that requires bending a new brake pipe with a different configuration from the original. To form the new pipe and trial fit it to the car we found it easier to remove the windscreen washer pump located on the firewall and to loosen the wiper motor mounting as well. “Easier” is a relative term! Not exactly easy to get to the nuts on the inside of the firewall to release the pump.

Easy is a relative term

Using the brake pipe supplied in the Bugeye brake pipe kit that has pipe cut to length with fittings installed for the pipe from the master cylinder to the pipe union proved to be a little too short so we have ordered some extra 3/16″ pipe from FedHill. The short pipe was used to go ahead and make the pipe bends that will become a model for the FedHill pipe when it arrives. 

We then went ahead and bent the pipe for the route from the union to the RH front wheel and the pipe from the union to the LH front wheel. The LH pipe runs over the front chassis crossmember and is held in place with two brake clips.

Crossmember brake pipe clips (2)

LH and RH front brake pipes at Union

To make sure that we did not end up with a conflict between the pipe and the steering rack we went ahead and temporarily installed the steering rack. Permanent installation will occur a little later.

At the front of the car the hard pipe attaches to a clip on the chassis where it is joined by a flexible black stainless steel Goodridge hose. The other end of the hose then screws into the brake caliper.

Brake hose to Brake pipe chassis clips

The brake pipe that runs from the union to the back of the car was removed, but we will wait until the engine and transmission are removed from the car to shape and install the pipe. There just isn’t enough room to maneuver to install the new pipe with the engine in the car. All of the original pipe was removed from the car and stored away just in case we need it in the future. The pipe may be ultimately tossed away but we will keep all of the end fittings.

Brake Pads – We had ordered new Gold Cup brake pads from Moss Motors only to discover that they were just slightly too thick, preventing a good fit in the new calipers. We ordered a set of EBC pads and like Cinderella, found that they were just right. These were installed with new spring retainers and split pins. We won’t bend the pins back yet.

EBC Brake Pads

New calipers, EBC brake pads, Retaining Springs and Pins

Installing the new steering rack acquired from AH Spares proved to be a simple job. The lower brackets were installed on the car with the three 5/16″ – 24 x 3/4″ bolts for each bracket. We have new shims to install in the cradle of the brackets but we aren’t going to install them now. We will wait to use the shims when the final installation on the car is accomplished after paint. After the brackets are mounted to the chassis, the rack can be lifted into place and the top brackets can be screwed into place. We left everything loose until the steering column and the steering rack were mated and the pinch bolt installed. Then everything was tightened down. The steering rack clamp bolts were torqued to 20 ft lbs. The steering rack mounting bolts were torqued to 17 ft. lbs. The steering column pinch bolt was torqued to 10 ft. lbs.

The Sebring-style pedal box was reinstalled with its proper foam gasket. The gasket doesn’t align perfectly and required some manipulation. We decided to glue the gasket/seal to the pedal box but used no adhesive between the seal and the car. Ten 1/4″ – 28 x 5/8″ stainless steel hex bolts and flat washers are used to secure the box to the car. 

Because the Sprite was manufactured to be set up as either a LH or RH drive, there is an opening in the chassis sub-structure for a pedal box on the RH side of the car. We fit a new pedal box blanking plate and gasket to this location to make sure everything fit but then removed them so they would not be damaged. The blanking plate uses only eight 1/4″ – 28 x 5/8″ bolts. We will install again after paint. While cleaning the area for the new blanking plate we discovered the original Cherry Red paint used on the car. Just a fun fact.

Original paint discovered

Blanking Plate Installed

The rebuilt front dampers were bolted in place in preparation for the installation of the front suspension. Each damper is secured with three 3/8″ – 24 bolts into captive nuts in the chassis.

Our next step will be to install the refurbished/new front suspension and brakes.

The Episode Thirty-three video includes the windscreen washer pump removal and the beginning of the brake pipe replacement with new conifer hard pipe. The rebuilt front dampers are installed along with the black Goodridge stainless steel brake hoses that connect the brake pipes to the calipers.The steering rack is temporarily installed and the EBC “green stuff” brake pads are installed in the front calipers. The steering rack is connected to the steering wheel shaft. The pedal box with its insulation seal are installed as is the new blanking plate and seal for the RH drive pedal box hole. The car’s original paint color is discovered.

Heater Blower, Fuel Pump Bracket, Washer Bottle and Bracket Removal

We have yet to decide if the heater will be retained in the restored car. Living in southern Florida makes the heater unnecessary, so we may just carefully store the blower and heater box with matrix away for safe keeping to be used at a later date. So, we removed the heater blower and documented the heater blower wiring.

The Old Fuel Pump Mounting Bracket Removed

Smiths Heater Blower Removed

The heater air-flow control cable is disconnected and the dash heater control switch is described in the accompanying video.

Horns, Air Intake, Steering Rack, Pedal Box Removal

This post covers the cleaning of the horns, the fresh air intake, the RH radiator brace and the old steering rack. A comparison of the old and new steering racks is made. The pedal box assembly with the single dual chamber master cylinder is removed from the car. New aluminum polished pedal covers are installed on the pedals of the new dual master “Sebring-type” pedal box. The replacement of the brake hydraulic pipes is begun with the removal of the pipe from the master cylinder to the brake pipe union.

The Hella horns were cleaned and the wiring checked out:

Front Suspension Chassis Clean-up and Further Disassembly

Steering Rack – Our next step is to remove the steering rack. We are going to replace the old rack with a new one from AH Spares. The tie rod ends were previously disconnected from the steering arms so this was just a matter of disconnecting the steering columns and removing the two aluminum brackets that secure the rack assembly to the chassis crossbar. To get to the rack we did have to remove the coolant overflow tank from the LH inner finder valance that was fastened to the inner fender with 1/4″ – 28 x 1/2″ hex head bolts and nuts.

Coolant Expansion Tank

The steering column was then disconnected from the steering rack by removing the special pinch bolt and nut from the column. Note that the bolt fits through the indentation groove in the steering shaft.

Steering column Pinch Bolt to Rack

The steering rack brackets are aluminum and consist of a lower piece with a cap. Once the caps were removed, the steering rack assembly could be lifted away.

On a left hand drive car, there is supposed to be a shim on the lower right hand bracket and we did find that to be in place. To our surprise there were two aluminum shims on the left hand lower bracket. These were apparently installed to compensate for the damage to the chassis crossbar. This will need to be investigated further at a later time.

With most of the front suspension components removed and out of the way, it is time to clean up the front of the chassis and get rid of the grease and grime. This looks much better than it did!

Cleaned Chassis crossmember

Video Episode Twenty-nine shows the removal of parts and the clean-up of the front of the chassis. The front shocks, the steering rack and its mounting brackets are removed. The rebuilt front shocks from World Wide Imports are received and painted. The fresh air intake and its mounting braces are removed. The horn wiring harness is disconnected from the horn relay and horns, and the horns are removed from the car. The location of the horn wiring harness clips is shown. Unfortunately, some damage to the front chassis is discovered and pointed out.


The following steps are addressed in the video:

0:00 – Front shock removal

0:20 – Steering rack removal

10:15 – Front of chassis clean-up complete

The front shocks were rebuilt by Jane and Peter Caldwell at World Wide Auto Parts. They do a great job with refurbishing the lever shocks. We are going to revert to these and give them a try before possibly reinstalling the front Bilstein tube shocks.

Rebuilt Front Lever Shocks

There are two wiring harnesses that run along the right inner fender valance. The smaller one is for the horn and the larger one is for the front lights and the electric radiator fan. The smaller horn harness is held in place by two “P” clips that are secured with Phillips head machine screws that are #10-32 x 1/2″ to captured nuts in the valance. 

Horn wiring harness

Horn wiring harness

The horn harness is routed to a relay with four wires. The dark red wire is connected to relay terminal 84, the blue wire is connected to terminal 87, the green/brown wire is connected to terminal 86 and the red wire to the horns is connected to terminal 30.

Horn Relay

Lower Horn

Horn Wiring Connections

There are two horns. The upper horn is mounted to the fresh air intake panel and the lower horn is mounted to the chassis via a bracket and two Phillips head #10-32 x 1/2″ machine screws. Power to the horns comes from the relay terminal 30 that feeds to a splitter with one red wire then routed to each horn. Each horn also has a black ground wire. 

The larger lights and fan harness is zip-tied to the RH inner fender brace. The air intake is also held in place with the brace.

Air Intake and Inner Fender Brace

Lights and Fan wiring harness

The inner fender brace is secured to the inner fender captured nuts with 1/4″ – 28 x 5/8″ hex head bolts. The bolts were removed as was the brace.

RH Inner fender brace

Removing components and cleaning unfortunately revealed chassis damage. The left front bonnet brace extension has been bent and the LH radiator upright has been previously repaired. These items will require attention later.
