Re: Replace Clutch

I have a '40 110 that just got an engine transplant.

I pulled the engine, left the trans in place; the car has OD and I didn't feel like pulling the trans, cross member and driveshaft, and yanking engine and trans complete. I cleaned up the PP and reused the clutch plate that was on the '40, it was in decent shape, although I did have a new disc in case it was toast.

The manuals (39-39 and the '40 supplement) spell out the trans removal process pretty well. It would be remove driveshaft, disconnect all linkage and wiring/cables (for the OD), support the trans, remove x member, remove trans as I recall. I think you can unbolt the x member and leave it connected to the trans, then secure it to a trans jack and shift it rearwards and down, and out she comes. You will want to support the rear of the engine/flywheel with a jack.

Reinstall for me included maneuvering the engine (with flywheel, clutch and PP) into the engine bay, with the throwout bearing duct-taped to the clutch arm so that I could align the input shaft to the bellhousing and clutch assembly. Once the input shaft had made it through the clutch (which took some doing, I was under the car, son was running both the cherry picker and a floor jack) we had the engine about 1/2" from seating fully. That took a bit of aligning to engage the pilot bearing. Once all that was seated, I reached up through the bottom of the bellhousing, pulled off the duct tape, and connected the spring from the clutch release arm to the transmission.

A trans jack, plus following the shop manual should make trans removal relatively easy (for people of our vintage. I'm 63 now).

Hardest part might be just getting the clutch aligned properly prior to install. I did not have a proper diameter/tooth input shaft alignment tool; I faked it by using a series of sockets wrapped with tape and an extension, and my M1A1 eyeball.
