    Fireball, do you know if these lines ever go bad? I know yours was pinched, but on the '70 that I used to combine with my '57, the lines looked fine, so I just plugged them back in and called it good. Not sure if I should replace the lines "while I'm at it" (famous words that are causing my project to drag out for YEARS). HAHAHA I know we've had this discussion before, and we came to the conclusion that two jeeps are better than one.

    Other than the spot that rubbed through, the current nylon lines seem fine. Not brittle, not discolored, no signs of age. They seem like they would be fine to reuse. Just make sure they aren't rubbing on any sharp body edges.

    My wife is good to her word and tonight was the night to drop the trans/transfercase out.

    Here we go:
    [​IMG]

    And it's out:
    [​IMG]

    it would have been out faster if I didn't forget the transfercase mount attached to the frame rail. Took a few minutes to figure out why we couldn't pull the transmission back.

    It's a lot smaller than the T18 that's going in:
    [​IMG]

    The T14 looks to be in good shape. I'll probably keep it around as a spare for the '69:
    [​IMG]

    Well there's a pilot bushing that isn't a stuggle. It came loose with the transmission:
    [​IMG]

    Looks like I need to resurface the flywheel. As bad as it looks visually, it feels perfectly smooth to the touch and should clean up fine:
    [​IMG]

    The pressure plate looks similar and the throwout bearing feels a little crunchy (when I got the Jeep, there were no clutch return springs and it was adjusted so the bearing was in contact at all times):
    [​IMG]

    Luckily I have a beautiful Valeo clutch/pressure plate/throwout bearing that came with the spare motor. It appears to have almost no use:
    [​IMG]

    Interestingly the different brand clutches are built different. Look at the difference in throwout bearing thickness:
    [​IMG]

    But when you stack the matching pressure plates and trowout bearings, they within 1/16" of each other. The new clutch should work fine:
    [​IMG]

    I'll drop the flywheel out tomorrow night so I can get it surfaced.

    I didn't have a cover plate for my motor so I also made one, out of 12ga. I trimmed the inside to match the rear of the motor and put a 10deg break on the upper parameter. Outside is all formed to the bellhousing. It's a little overkill but the Ross steering does hit it at times and I wanted it to be as water (mud) tight as possible. We have a lot of water crossings I want to try and they can have surprises.

    when I put the jeep T 18 into my jeep
    I had the input retainer OD cut down to use the T 14 release bearing
    also it had to be shorten . as it was touching the hub on clutch disc
    some things you can measure . when you have both units sitting side by side . straight edge across bell housing
    to measure the depth of things . :watch:

    I cheated and bought the Novak input retainer that's pre-machined to GM specs. GM index size for the bellhousing, GM release bearing size, and shortened. That said, I'm still going to measure everything for the best possible chance of everything working.

    I bought the Ford retainer and used a Ford to bearing. Clutch fork had a short date with the flap disc . I'm cheap ..

    But the throwout bearing length depends on the type of clutch used. The diaphragm type usually take the short version and the B&B to long. But not always as I found out with the McLeod. I ended up remachining the adjustable pivot and using Mcleods adjustable length bearing. Sort of a pain in the posterior.

    Yeah, that was my measurement last night. I was suspicious the bearing lengths were so different but when I measured with the pressure plate they were less than 1/16" different overall thickness, so it looks like the new(er) clutch/TO bearing will be OK.

    Flywheel is off so I can drop it off at the machine shop:
    [​IMG]

    Amazingly, given all the oil everywhere, the rear main seal doesn't seem to leak at all:
    [​IMG]

    Some clutch measurements.

    The thickness of the old unknown brand clutch/throw out bearing:
    [​IMG]

    And the new(er) Valeo one:
    [​IMG]

    It's actually closer to 1/8" difference. There should be enough adjustment in the cable. The Valeo parts are from the 225V6 CJ kit and were functional in a 1971 Jeep prior to me getting them.

    For other measurements, the rod input shaft barely protrudes past the bellhousing face and the end of the bearing retainer is about 3 18" back from the face of the bellhousing:
    [​IMG]

    The input shaft of the T-14 protrudes about 1/4" more past the bellhousing face (whitch is expected) . The end of the bearing retainer is less than ten thousands different from the Novak modified T18 part:
    [​IMG]

    Things generally look OK. The clutch/TO bearing is my biggest risk, but I think it will work.

    Post surfacing. Beautiful:
    [​IMG]

    I was smart enough to mark it before removal so I didn't have to try six times to get hte rotation right:
    [​IMG]

    Since it's way too tight up front to get a wrench on the crank bolt, I used some long bolts and a pry bar to hold the engine while torquing the flywheel bolts:
    [​IMG]

    Interestingly, the new pilot bushing isn't very tight either so I've got it set in place with red lok-tite. I'll let that dry overnight before I put the clutch on.

    this https://www.henkel-adhesives.com/us/en/product/retaining-compounds/loctite_603.html is the correct retaining compound for sintered bearings.

    This https://www.henkel-adhesives.com/us/en/product/retaining-compounds/loctite_638.html is the product I used when I had my intermediate gear machined for the AA modification.

    The machinist bored the gear on one side with a slight taper to the interior of the gear so the race would press in, but be loose when fully seated. I was not confident at the time of my ability to perform the work, but am fully confident I can do it if this retaining compound fails.

    Although I'm quite sure this product works very well, I personally work be reluctant to use it. If after using this product, for whatever reason I need to replace the pilot bushing, I don't like the idea of heating the end of my crankshaft to 250*C (482*F) to break the bond.

    I wish I had a way to knurl it. Since it's completely captive once things are assembled, I just need it stuck well enough to say when I pull the clutch alignment tool (an extra input shaft) out. After than, it doesn't matter much what happens.
