Clutch/Gearbox and Propshaft Assorted Modifications

Posted on by

The system consists of the clutch, gearbox, overdrive, and propshaft. The original driveline system included the following:

Clutch: 10” Borg and Beck hydraulic

Gearbox: “side-shift” 4 speed

Overdrive: Laycock de Normanville electric

Propshaft: Hardy Spicer universal joints

Flywheel: 28 lb.

Driveline Modifications

Toyota 5 Speed Conversion

Although I always enjoyed the Laycock de Normanville electric overdrive in my car, I knew my tranny needed to be rebuilt. Rather than go that route, I took advantage of Smitty’s five speed conversion kit and installed a Toyota gearbox in the Bloody Beast. The Toyota Gearbox is quite a bit lighter and folks say that it runs  a bit cooler than the original box.

You can use a number of different Toyota gearboxes from the non-turbo Supras or from several of the 2 wheel drive pick-ups. I used a W57 1998 Toyota Tacoma 4×2 VIN# 4TANL42N2WZ094878. Details are available in the restoration blog, but this pdf document put together by Tracy Drummond is very helpful. Drummond Five speed gearbox conversion.

The kit includes several custom components including a bell housing casting unique to the conversion.

The kit is no longer available from Smitty, but Pete Delaney now handles the product. His contact information is as follows as of July 10, 2012:

Clutch Conversion

Many who have the early 3000s and who complete the 5 speed conversion also adopt the BJ8 9/12″ diaphragm clutch. It is less demanding on the left leg muscles. I went ahead and made this conversion while I was at it. This also requires using a BJ8 flywheel. I obtained a 24lb. lightened flywheel from Bill Bolton.

Slave Cylinder Bleeder Pipe Extension

Anyone who has bled a Healey slave cylinder knows that the bleed nipple is not exactly easy to get to. Doug Reid aka “Mr. Finespanner,” fabricated an extension for me that makes the job much easier with the bleeder actually accessed from the engine bay. This has now become a popular item used by many aficionados.

Custom Propshaft

Installing the Toyota 5 Speed does require making up a new propshaft, which I had done at a local speed shop. The propshaft does need to be balanced prior to installation.

Chapter 70 Week Forty September 17, 2007

With a little help from a work colleague, my wife and an engine hoist I was able to get the motor with bell housing into the car without one scratch or knick in the paint! We took our time and patience paid off. I tightened down the engine mounts and then put a short jack stand under the bell housing to support the rear of the engine.

Helper One

Helper 2

Motor mount tightened down

I had previously bled the slave cylinder so it was an easy task to mount it to the side of the bell housing, insert the Smitty provided push rod, and try out the mechanism by pushing the clutch pedal. The longer fulcrum pin I had made (with directions from Tracy Drummond) worked perfectly. Special thanks to my engine installation assistants – couldn’t have done the job without them.

I did take a minute to install the engine identification number plate on the engine block. I had a new one made by Clarke Spares & Restorations and it looks very authentic.

Engine Number Plate

I am going out of the country for two weeks so things will have to sit a while until I return and get back to work. The next step will be to pull the engine back out, attach the gearbox to the bell housing, fasten the assembly to the engine and put it all back in the car. I suppose I could have skipped the clutch test, but what are a few more hours in a six year restoration!

Chapter 69 Assembly Week Thirty-Nine September 10, 2007

The next job to be tackled was the installation of the rivets for the rear shroud to the frame. There are 19 aluminum flush face rivets for the lower lip of the car and another 13 rivets that attach the shroud to the rear boot frame rail.

First, I put a healthy bead of 3M body caulk between the two pieces to keep water out of the boot. I clamped things together as best I could and inserted pop rivets in the frame rail just to line the components up properly. The aluminum rivets for the lower lip were sourced from British Car Specialists. I purchased a rivet squeezer tool from Brown Aviation Tools with the 2003-16 1/8” rivet set to use for the job. An expensive tool at $135 for one little job! The tool worked nicely. After an initial “squeeze” with the tool, I put five small #10 washers on the rivet set to pull them closer together and squeezed the rivet again. I ended up with a very satisfactory job. As per original specifications, I then painted the lower lip satin black.

Rivet Squeezer

Lower Rivets installed

There just wasn’t room to use the rivet squeezer for the boot rail-to-shroud assembly so I used 1/8” diameter, 1/4” long aluminum pop rivets for the job. The nose of the rivet gun wanted to hit the boot lip so I put about three thicknesses of blue painter’s masking tape around the area to protect the paint. I did get two small nicks that were touched up, but otherwise the project was a success. It pays to take your time on the rivet job if you are assembling after painting.

Pop Rivets installed

Following the rivet work I installed the rear bumper bars and rally bumpers supplied by Cape International. New rubber grommet seals were installed on each bar, paying attention to the LH/RH designation. I am very pleased with the look of the rally bumpers, although one is not afforded much protection by these full bumper replacements!

Rally Bumpers

The next task was to install the boot lid. This turned out to be pretty easy. Again I protected the body with some blue painter’s masking tape and with the help of my wife, put the lid in place and tightened down the boot hinges. After getting the lid in place, I needed to adjust the boot lid striker so that it would fit properly to latch the boot lid. I then attached the boot lid control cable to the lower hinge post and I was in business!

Boot Lid Installed 2

Back End Finished

Before the final installation of the engine, I decided to fit the clutch assembly and Smitty Bellhousing to the block and put in the car to make sure the clutch was working properly. I wanted to make sure that I had sufficient room for the clutch fork to function once connected to the slave cylinder. Some might call this a little anal, but if you install with just the bellhousing and not the gearbox, you can view everything to ensure success later!

Engine Removal, cont’d

Gearbox mounts –  Removed 4 bolts securing the gearbox mounts and 4 bolts and nuts from the Propshaft at the gearbox union. The bolts on the gearbox side cannot be removed without removing shaft nut. There were also 2 nuts of the same size to remove on the underside of the chassis. Finally, the nut and securing pin on the gearbox stabilizer must be loosened and removed to free the gearbox.

Propshaft Removal

Clutch slave cylinder – Detached the cylinder from the bell housing by removing 2 bolts. Must also release the clutch operating lever by removing the cotter pin from the clevis pin.

Disconnected the wire clamp on the bell housing and unclipped the wire to the gearbox switch for the overdrive.

Engine Hoist – We then thought we were ready to connect the hoist and remove the engine and gearbox as one unit. If we were doing this again, we would have waited until the shroud was removed to avoid any damage. It would have also made it easier to swing out the entire unit had we jacked up the car a bit first. That would have given the gearbox more room to swing vertically. Providing enough lift height on the hoist is a bit of a problem given the length of the combined engine and gearbox and the angle needed to successfully remove the unit. 

We also decided that while it isn’t theoretically necessary, it would be easier to pull the engine if the brake reservoir were removed. So we gave up due to darkness and gently reset the engine in the bay.

Hydraulic lines –  Removed the hydraulic lines from the master cylinders to the reservoir canister. Note double clasp or clip on fender secured by a nut and bolt on outside of fender well. The longest pipe is the brake and is connected closest to the front of the car. Shorter pipe is the clutch line.

Attempted to remove the engine with the lift again. This time with better light, a less crowded space and with the lift chain adjusted we easily removed the engine and transmission.

Clutch Assembly and Ready For the Engine Stand

To mount the engine on the stand it was necessary to remove the gearbox from the engine. The bell housing was secured with 9  3/8” x 24 bolts including two that mount the starter. The bolt on the top right secures to the engine block without a nut. All other bolts have nuts. After removing the transmission we then had to remove the clutch. You must gradually slacken the cover screws a turn at a time until the spring pressure is relieved.

Clutch Assembly 2

After the clutch assembly was removed, the flywheel was exposed. Four nuts with the lock washer straps were loosened. The crankshaft pulley must be held on the front of the engine to prevent the shaft from turning.

Wings

The Front Wing – Removed 3 bolts joining the front shroud and the front wing below the headlight. These are slightly shorter than those used to secure the top of the shroud and the wing together. They are tightened to spring-clip type nuts. Removed the headlight and sidelight. The sidelight is fastened with three small screws and nuts on the reverse side. Two pieces of plastic piping are found above and below the sidelight. Four brass nuts accessible beneath the wing hold the headlight bucket in place. Seven bolts fastened the shroud to the wing along the top edge. Three bolts and nuts secure the wing to the frame along the bottom edge. Seven small self tapping screws fasten the wing in the door jamb to the hinge pillar.

The Rear Wing – Removed three bolts inside the interior and three inside the boot to remove the rear wing. The bolt located closest to the rear of the car, but still in the interior has a regular nut rather than a clip spring nut which must be held with a wrench when removing. There is also a screw near the door under the aluminum trim that fastened into a steel plate. At the bottom of the rear wing there are two bolts and nuts securing the wing to the frame and a vertical drive sheet metal screw. Finally, eight cross-head screws with nuts fix the wing to the door shut pillar and they must be removed.

Clutch

The 1964 MK2 used a spring-loaded, hydraulically-operated, driven plate assembly with cover and a graphite release bearing. Later models switched to a diaphragm clutch. While the diaphragm cultch is probably easier to operate, I decided to stick with the original type in my restoration. The entire clutch assembly was purchased from SNG Barratt and installed by my engine builder, Mike Gassman, from Gassman Automotive. The unit was balanced with the engine for smoother running.

Fortunately, the replacement slave cylinder sourced from SNG Barratt is exactly the same as the original. the rubber boot is somewhat different, but otherwise identical. The new return spring is; however, shorter than the spring currently on the car. Not sure if it is a different spring or if the original is stretched. In any case, I shall try the new one (which did have the proper Jaguar part number) and see how everything functions.

The Jaguar Service Manual states that “there should be 3/4″ free travel or unloaded movement at the pedal pad before feeling the resistance of the clutch thrust springs. The free travel is most easily felt by depressing the pedal pad by hand until a marked resistance is felt. Adjustment is effected by slackening the lock nut and turning the operating rod between the slave cylinder and the clutch withdrawal lever. Screwing the rod into the knuckle joint will increase the pedal travel; screwing the rod out will decrease the free travel.”

Gearbox and Overdrive The gearbox is a four-speed type with synchromesh on the second, third, and top gears. The overdrive is a Laycock de Normanville. First and reverse gears are 12.731:1, Second is 7.012:1, Third is 4.836:1, and fourth is 3.77:1; with the overdrive engaged the top gear ratio is 2.933:1. A synchronized fiord gear was added later in production.

According to Nigel Thorleys excellent book – Original MK1/MK 2 the all synchro box was fitted in Sept 1965 from chassis no 119200 – 2.4 RHD 127822 – 2.4 LHD 169341 – 3.4 RHD 180188 – 3.8 LHD

Mike Gassman, http://www.gassmanautomotive.com refreshed the overdrive and the gearbox was sent to Quantum Mechanics in Connecticut. Both units were in good repair with the exception that the 3rd to fourth shift fork was bent and was replaced. The gearbox also had all bearings, synchronizers, seals and gaskets replaced. The gears were in good shape. The overdrive was cleaned, an overdrive rebuild kit installed and reassembled in good working order. A new solenoid was affixed and the system was tested.

Change-Speed Lever Assembly (Gear Shift) The  change-speed lever has single flat washer above the selector lever.

There is a two part rubber bush inside the selector lever through which the selector shaft passes. There is a flat washer at each end of the bush. The washers have different diameter holes appropriate to the shaft size at each end of the lever. I cleaned the selector lever and painted it with POR-15. New rubber bushes were also installed.

There is a bronze bushing in the selector lever through which the pivot pin passes. This bush was also replaced with a new component. A new fiber washer is located on each end of the pivot pin. A double spring washer  is located on the pivot pin and the assembly is held together with a slotted nut and a split (cotter) pin.

The correct lever knob for the early Moss gearbox (without first speed synchro) is a tear drop shape. The later box used a round shifter ball. A locking nut secures the shift knob to the shaft.

I ordered a new lever shaft and discovered that what is being supplied now is 3 inches shorter than the original. I will probably have my original lever shaft rechromed and use it.

Fasteners for Gearbox to Engine The original fasteners were in good shape, no doubt due to the thick coat of oil and grease that encapsulated them! I media-blasted the bolts and nuts and had them zinc plated for use upon reassembly. There are eleven hex head bolts 3/8″ – 24 x 2 7/8″ with two 3/8″ – 24 nuts and shakeproof washers, and four 3/8″ – 24 x 1 3/8″ hex head bolts with four 3/8″ – 24 nuts and shakeproof washers.

Cover Plate at Front of Clutch Housing  The cover plate is fastened to the engine backplate with four #10-24 x 1/2″ hex head bolts and shakeproof washers. It is installed when the gearbox is mated to the engine when the two components are separated by approximately 2″. At that time the cover plate is slid into position and tightened against the lip of the gearbox bell housing with the four bolts.

Gearbox/Engine Mating

On June 18, 2016 in preparation for the preliminary installation of the engine and gearbox into the car for testing, I mated the two components together using the bolts referenced above. In the cases where nuts are used, all nuts are found on the bell housing side. I had to wrestle with the gearbox a bit to get it to seat properly, but I eventually got there. One must be careful to keep the gearbox mainshaft level with the crankshaft to avoid bending the shaft.

Gearbox Mainshaft

I used my engine hoist to hold the gearbox at proper height during the exercise. Several long 3/8″ bolts were used to align the bell housing and the backplate of the engine, prior to inserting the proper bolts and pushing the gearbox home. As mentioned above, then the two components are approximately two inches apart, the clutch cover needs to be inserted and bolted in place.

Gearbox/Overdrive Lubrication

After installing the engine and gearbox in the car I filled the gearbox and overdrive with oil. Mike Gassman, at Gassman Automotive, recommended using Amalie Elixir Full Synthetic GL-5 Gear Lubricant. The Jaguar MK2 Service Manual indicated that 4-3/4 pints of lubricant should be used.

Amalie Elixer Full Synthetic GL-5 Gear Lube 75W-90

This image, although a little out of focus, shows the fill plug near the top and the drain plug at the bottom of the gearbox. The overdrive fills though an internal hole from the gearbox to the overdrive.

Drain and Fill Plugs for the Jaguar MK2 Gearbox

While I could have used my hand pump to pump the gear lube from below into the fill hole, since my interior is not installed I removed the fiberglass gearbox cover and filled from above. I inserted a clear tube into the fill hole and routed it to the interior. I found that it actually took a little closer to 4- 1/2 pints to fill the units, even after waiting some time to allow the fluid to flow to the overdrive. I filled the gearbox until the gear lube began to leak out of the fill hole.
