Engine Post-Installation Check List

Having just installed my engine and gearbox into the car chassis, I thought it might be useful to keep track of the various related installations and connections that need to be made before one turns the ignition key and hits the starter button to fire-up the refreshed engine. I will try to journal this check list of items in the sequence that they are addressed, though I may find that I need to modify the chronology as things unfold.

1. Water temperature sensor wire:

2. Oil Pressure Sensor Wire:

3. Dip Stick – I discovered that the placement of the electric steering pump interfered with the free travel of the dip stick. I found it to be easier to shorten the dipstick than to move the pump!

4. Heater Feed Pipe Hose Connection to Intake Manifold:

Intake Manifold Feed Hose to Heater

5. Heater Return Pipe Hose Connection to the Front Return Pipe at the Side of the Cylinder Head – the XK’s Unlimited stainless pipe does not fit well so I have ordered and offset hose to hopefully compensate for the poor fit.

6. Checked the firewall wiring Ground Strap to Chassis path to make sure all of the wiring is routed under the heater pipes, clutch hydraulic pipe and hose and the alternator cable, note the position of the clips. On final assembly the loose wiring will be in a wire look cover:

11. Plenum drain hose – The drain hose was secured to the plenum pipe at the firewall with a hose clamp and routed between the chassis and the transmission, behind the throttle linkage. I zip-tied it to the ground cable at the firewall to make sure that it did not rub against the throttle linkage:

12. Installed the alternator and its primary cable from the ANL Fuse on the LH engine bay valance. I took advantage of a captive nut already located on the valance as a place to install a yellow-zinc clip to secure the alternator cable.

17. Reverse and Top Gear Switch Wiring at Gearbox – Rather than routing these wires as Jaguar did (through the gearbox tunnel) I decided to install a rubber grommet in the tunnel and run the wiring to the interior of the car. Each wire was then connected with two-way snap connectors and will be hidden by the central console:

18. Change Speed Lever, Rubber Grommet and Retaining Ring – I removed the lever knob and slid the grommet over the lever shaft ( a little petroleum jelly doesn’t hurt), punched holes in the grommet with an awl and installed the ring and grommet with four #4 x 1″ chrome slotted finishing self-tapping screws.

19. Breather Assembly – The breather hose/pipe for the engine originally routed to the air cleaner where the mist would be recirculated into the carburetors. In my case, I am not using the original air cleaner and I did not want to recirculate the emissions from the breather pipe to the fuel system anyway.

I chose to use a catch can manufactured by Mishimoto. The can is a very clever design.

Mishimoto Compact 2 Port Catch Can

Of course, a Jaguar owner cannot have a product with a Japanese name on it visibly mounted in the engine bay, (never mind that many of the newer parts used in the restoration probably were produced in China!) so I chose to mount the can on the front suspension crossmember. At this location it is very easy to access to check accumulation. I also used a K&N Filter for the outlet port.

The elbow hose from the breather port on the engine is a 5/8″ I.D. but the fitting on the catch can is a 3/8″” barb so I used a barbed brass step down fitting between the 5/8″ hose and a 3/8″” hose. The straight emissions hose runs from the elbow almost straight downward, and parallel to the servo breather hose, to the catch can.

These photos are dark and it is a challenge to see the mounting of the can. I was able to use a hole that was already in the front crossmember so it was not necessary to drill any holes to mount the catch can. Always a pleasing outcome!

Slave Cylinder Hydraulic Pipe

A hard line attaches to the flexible stainless steel hose at the cylinder head bracket (shown above) and connects to the slave cylinder. It is held securely by one clip attached to the bell housing. The new line was sourced from Classic Tube along with the pre-bent brake lines.

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.

Clutch Slave Cylinder

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.

Ground Strap

The ground strap was connected to the engine/bell housing prior to installation in the car. A new ground strap was sourced from SNG Barratt. Note the proper location of the strap:

Propshaft

The propshaft with the two flange yokes attached is just under 48″ long. The shaft seems to be in good shape, but I went ahead and replaced the two universal joint journals and bearings. Following installation of the universal joints I greased the two units and then cleaned the shaft well to send to Driveshaft Specialists in San Antonio, TX  http://www.driveshaftspecialist.com  (Jeff, 866-455-6622) for balancing.

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.
