Storing the Original 948cc Motor

Engine & GearboxMy Dad built a new house and he is “downsizing,” so some car parts are needing to go to a storage unit. When we upgraded to a 1275 motor and Datsun 5-speed gearbox, we kept the original 948cc. I will never plan to go back to the 948, but if the car is ever sold it will be nice to have the original numbers-matching engine. Apparently, the original gearbox was replaced with the ribcase box somewhere in its history..He has a climate controlled unit, but the motor and gearbox needed to be put away properly so he built a nice plywood box for the storage unit.

Fluids were drained, and Marvel Mystery Oil squirted into each cylinder. Desiccant plugs were purchased from Moss Motors and installed in place of the Champions. Holes were plugged and the top of the box was screwed in place. Who knows when this motor and gearbox will see the light of day again!

New Tires & Fuel Pump

I am a little late recording this, but in September 2010 the Bugeye’s shoes were replaced. While the tread on the Wynstar tires looked just fine, they were over eight years old, so for safety sake it was time to replace them. The same tire was no longer available, so the Bugeye now has some P185/60R13 80 H Sumit HTR 200. These tires are not the same low profile as the Wynstars, but the ride is superior and the grip firmer than before. Details are available on the maintenance page of this site.

The Sprite was neglected a bit over this winter, so when a warm day came round near the end of February, it was time to start her up and give her a good run. Alas, no joy! Either the SU fuel pump was not sucking fuel or there was a clog in the line. After a few diagnostics, it became clear the fuel pump was the culprit. A negative ground electronic SU was ordered from Moss Motors and installed. While messing with the pump, it seemed the ideal time to switch out the old rubber fuel hose for a new hose that is no susceptible to deterioration from ethanol. That done, the Bugeye is now happy and running once again!

2008 Encounter

Ready to AutocrossThe Austin-Healey Sports and Touring Club – A Car Club for Healey, Austin-Healey, and Austin-Healey Sprite Owners and Enthusiasts with regions in New York, Pennsylvania, Delaware and New Jersey always puts on a great annual event referred to as “Encounter.” The event is held in August of each year.  A judged Concours, popular vote car show, a rallye, tech sessions, a gymkhana, funkhana, valve cover races and a flea market are just a few of the usual events. Click the image to the left to view a slide show of the 2008 event held in Carlisle, PA.

My dad and I attended this year. I drove the Bugeye and he drove the “Bloody Beast,” his recently restored 1960 Austin Healey 3000 BT7, from Harrisonburg. We couldn’t attend when the event got started, but we headed up to Carlisle at about 5:30 am Friday morning, attended activities on Friday and Saturday and headed home Sunday morning. We enjoyed the great weather, and had a wonderful time. I had fun at Del Border’s gymkhana course and the “Bloody Beast” took home first place in the MK I category for the popular car show.

A New (And Proper) Master Cylinder

Although I had converted the front drum brakes to disc brakes not long after purchasing the Bugeye, I had not been able to find the proper 3/4” piston version that would have been used on the 1098 cars. My dad was able to source one from California during the previous winter, and in early August he installed it. He ordered the new master cylinder from Gerard Chateauvieux at Gerard’s Garage http://www.gerardsgarage.com Both the clutch and the brake master bores are 3/4″. The push rods are also shorter than the originals. More information is available from theses two pdf files:

After bleeding the brakes and clutch we did end up with improved brake pedal feel and stopping power. He removed the entire pedal box, installed the new master and then re-installed the pedal box.

2006 Gettysburg Car Show

The regional MG club held a popular show (no judging – just display) in Gettysburg, PA. Tyler, Scott, Dad and I attended. I drove to Gettysburg with Tyler navigating. It took us about 2 hours and 40 minutes. The show was held at a shopping mall but they had a great display area set up like a Main Street. It was a short show, 9:30 – 1:30 but we had a good time and saw some nice cars. Three Bugeyes were in attendance and approximately a dozen big healeys from the Capital Area Healey Club.

A Functioning Horn

The Horns

The horn had not worked in the Bugeye since we bought it – not very safe since the bugeye is one of the smallest things on the road. It was time to fix it. The horn itself when tested sounded very weak so I ordered a Hella twin tone horn kit. It came with mounting brackets and a relay for the price of $23.00!

Horn Wiring Diagram

My horn button is a little different from the original since I have a Moto-Lita wheel, but I ordered a new push pin for it – the 948 Bugeye variety. The pin needs to go into the wheel with the plastic end toward the dash so that the pin is insulated from the body of the aluminum wheel hub. Then the brass sprung pick up on the back of the horn button needs to line up with the pin. The entire assembly then pushes into the wheel hub. A brown wire from the brass contact ring on the dash cone runs to the horn relay.

I decided to mount both of the horns on the right front lower side of the frame. That way it was not necessary to run wiring across the frame below the radiator. On one horn I used the original mounting bracket, and on the other I used the supplied brackets and drilled two holes into the fresh air hose mounting assembly. I mounted the relay just above the horns.

The wiring diagram provided on the box of the horn was helpful. I provided a separate ground wire for each horn. The brown ground wire from the wheel  was connected to terminal #85 on the relay. The green wire form the fuse panel was connected to terminal #86. A red wire was used to connect terminal #87 on the relay to the positive terminal on each horn. This required putting a twin bullet connecter on the wire from the relay to splice a second wire to go the 2nd horn. Finally, a blue wire was run from the non-switched side of the fuse block to the relay terminal #30 to complete the circuit.

The horn now works great! It sounds like the biggest car on the road.

The Rear View Mirror

The rear view mirror in the Bugeye wasn’t the original and it looked a little worse for wear so I replaced it with a new one from Moss. It wasn’t easy to get to the mounting screws because of the rake of the windscreen, so I bent a screw driver with a torch to make a tool that would do the trick. Worked like a charm!

Flashlight

We used to carry a magnetic mounting flashlight under the cowl, but it never stayed very well. We picked up a mounting bracket for a light at VIR and I finally got around to installing it in the car. I selected the left rear mudguard as the location.

Dash Fascia and Gauges

When we bought the Bugeye, it came with a working tachometer and a dead speedometer. After thinking about having the original instruments refurbished or buying new ones I decided to buy new Smith’s gauges. Keeping the original tach would have involved installing the guts of an electric tach into the casing of the old gauge since we had previously installed an alternator making the original worthless since it had a mechanical drive off the back of the dynamo.

So the new gauges were ordered from APT Instruments, but it would be terrible to install them in the old dash so replacing old vinyl with new naugahyde was the only thing to do! I began the removal of the dash and proceeded slowly, carefully labeling the wiring to each instrument or switch.

I initially disconnected 2 orange/yellow braided wires to the wiper washer pump. Using a micro switch, my dad had previously converted the manual pump for the windscreen washer to an electric pump. Next was the heater switch. I disconnected a green/brown wire from the harness from a black wire to the heater switch. Then I disconnected a black wire from the heater switch body from a double bullet connector into a light green wire.

The turn signal wiring was next. The switch has three spade connectors. On the side with tow spades, a yellow wire attached to one and a blue wire to the other. A white wire was disconnected from the side of the switch with the single spade.

The Ignition Switch followed. The switch had four screw terminals. The top right terminal had 2 red wires joined together. The top left terminal had 1 heavy gauge yellow wire. The bottom right terminal had two white wires joined together and an red fused wire from the the electric fan switch that had been added. Finally, a large blue wire was disconnected the bottom left terminal. A previous owner had fabricated a clamping system to hold the ignition switch in place, that while primitive, did work. It will be replaced later.

Has three wires: the black ground wire was removed from the top spade terminal, the blue power wire from the switch to the fan itself was removed from the middle spade and the red wire with fuse to the ignition was also disconnected.

The Horn

Had one brown wire from the horn trim ring to the horn itself. The wire was disconnected at the bullet connector.

After removing the starter button and cable, the choke cable and the heater air control assembly cable, and the grab handle, the dash was removed from the car. Two ¼” hex head bolts secured the dash to the body on the left and right side. Two chrome phillips head screws fastened through two brackets from the firewall to the dash and finally one nut is fastened to a stud located centrally at the top of the dash.

Recovered Dash

Then it was time to recover the dash. I purchased some naugahyde at a local fabrics store and some contact cement and went to work. This is the result:

Aluminum Racing Pedals

My dad had installed racing pedals in the Big Healey and thought they did give a better pedal feel in addition to looking cool, so I bought a set for the Bugeye as well. They do look nice. I did not use the racing pedal for the accelerator pedal as it was just too close to the brake.

Engine Clean-up and Reinstall

One of the things I wanted to accomplish with the engine clean-up was to have the  exhaust header coated to reduce heat in the engine compartment and interior. I used Swain Coatings. The header came back looking great. Time will tell if the coating holds up and is effective in reducing heat.

I also did a general cleaning of the engine including a new paint job while the gearbox was being worked on by Jack Harper. I replaced the oil sump gasket and the rocker cover gasket, too. I tested and reinstalled the gear reduction starter. The air cleaners were cleaned and oiled with K&N products.

I developed the following list of items for reinstalling the engine and gearbox into the Bugeye:

Reinstalling a Bugeye Engine and Datsun 5-speed Transmission

  1. Grease the shaft splines on the engine and the yoke before installing the engine.
  2. Set the exhaust header in place so that it will be positioned to install once the engine is tightened into its mounts.
  3. Guide the motor into place with the lift so that the yoke on the driveshaft lines up with the transmission. If this does not work then remove the driveshaft and install after the engine and transmission are in place.
  4. Loosely secure the engine to the front motor mounts. The mounts themselves should be loose then tightened after all bolts/nuts are in place.
  5. Install the long bolts up through the crossmember into the rear transmission mount and tighten.
  6. Tighten the front engine mounts.
  7. Center the transmission in the rear mount, then push it as far to the right as possible, and tighten the transmission pad mounts on the bracket.
  8. Install the bolts in the sides of the transmission rear mounts from inside the car with the self locking nuts inside the tunnel. (Hint: tape the nuts in the wrench to make starting the threads easier.)
  9. Replace the gearshift lever.
  10. Connect the ground strap to the frame of the car.
  11. Replace the rocker cover and connect the breather hose.
  12. Install the intake and exhaust manifolds.
  13. Install heat shield and carbs.
  14. Connect throttle and choke cables.
  15. Connect breather hose.
  16. Connect hot water hose to copper tube and connect to radiator hose. Tighten clamps. It is easier to put the clamp on the hose/copper pipe when the copper pipe clips are loose from the manifold.
  17. Connect the short hot water hose from the water control valve to the heater.
  18. Connect the electrical cable from the gear reduction starter to the starter solenoid.
  19. Connect the oil pressure pipe to the fitting on the engine block by the banjo bolt.
  20. Reconnect the white/black line from the electronic ignition to the distributor.
  21. Connect the high tension line from the distributor to the coil.
  22. Reconnect the plastic terminal (3 wires) to the alternator.
  23. Connect the fuel line from the fuel pump to the carbs.
  24. Reattach the water temperature sensor to the engine head.
  25. Remove the banjo bolt where the oil line exits the rear of the block. Pour motor oil down the hole in the block to prime the oil pump. Reinstall the bolt.
  26. Remove the oil filter and pour it full of motor oil and reinstall.
  27. Fill engine with oil – Castrol GTX 10W-40.
  28. Fill the gearbox with Gear lube – Redline MT90. 2 1/4 pints. Use long clear plastic tube. Try pump.
  29. Connect the stainless steel flex line from the master cylinder to the slave cylinder.
  30. Bleed the clutch slave cylinder. (See Page 9 of Rivergate’s manual)
  31. Install radiator and fill with 50% coolant and 50% distilled water.
  32. Fix the carb drain lines to the mounting clamp at the lower rear of the engine compartment.
  33. Insert the 1 ½” connecter pipe (with sealant) for the exhaust system into the header pipe.
  34. Install the exhaust and muffler assembly.
  35. Tighten clamps on the exhaust connecter pipe.
  36. Reconnect the battery cables.
  37. When ready to start the engine, pull the spark plugs and spin the engine with the starter until the oil pressure goes up to normal on the pressure gauge, and stays.
  38. Check for any oil, coolant and fuel leaks.
  39. Reinstall the spark plugs and start engine.
  40. If engine does not start turn distributor 180 and try again!
  41. Install 4” fresh air heater hose and clamp.
  42. Install the leather shifter cover and surround.

Pulling the Engine for Minor Repairs

July 2006 Bugeye It is time to fix some of the problems we have lived with for a while and to make a few improvements. The oil leak we caused when we failed to seal the oil sump properly, the gear grinding in 2nd and 3rdin the gearbox, jet coating the headers among other things will improve the car for the future. These improvements require pulling the engine. We bought a cherry picker and an Oberg tilt lift rather than continuing to rent at $45 a pop. The following details the process to get ready to lift out the engine: Disconnected the battery positive lead from the terminal. Drained the engine oil, tried the gearbox, but couldn’t get the plug out so will return to that. Disconnected the ground strap and removed the two gearbox mounting bolts from the bottom of the car.

Loosened the right hand motor mount from the car so that it will lift free with the engine, but will not completely disconnect until the engine lift has the pressure off of the mounts. Loosened the screws to the engine at the mount on the left side of the car. The left mount will stay in the car.

Removed the cardboard heater hose to have it out of the way from the engine when it is lifted.

Connected the Lift Chain to the Rocker Shaft mounting studs and lifted the engine from the car.

Conversion to 1275 Engine & 5 Speed Gearbox

I am creating this post after the fact. Twenty-one years after the fact to be precise!

Unfortunately, I don’t have precise records, but in 2000-2001 we decided that the 948 cc engine just wasn’t powerful enough to provide the driving fun that I had hoped to experience. After shopping around a bit and doing some research my Dad and I decided to purchase a 1275 motor from Bill Perry at Rivergate. Bill completely rebuilt a 1275 that he had and added a new aluminum head. We also purchased a Datsun B210 5 speed gearbox conversion and had Bill assemble everything as one unit, crate it, and send it to us, essentially ready to install.

The engine numbers 12V/587Z/L7183. This engine was sourced from either an Austin-Healey Sprite, MK4 or from an MG Midget, MK3. The 587 engine was produced for North American Sales and was apparently rather rare in the States, so it may have been a Canadian car. The “L” stands for low compression, that is 8.0:1. The engine was produced  from 8/1971 to 8/1972. The engine, as produced at the time, would have been painted black.

Bill recommended using a Crane “Fireball” XR700 optical trigger ignition system and we installed one shortly after receiving the engine/gearbox package. We also purchased and installed the speedometer adapter kit available from Rivergate.

Rivergate Prepared 1275 Engine and Datsun 5 Speed

1275 Engine and Datsun 5 Speed

Before too long we also converted the original starter to a high-torque gear reduction starter and the generator to a Lucas alternator.
