I put my new motor in my 240sx (KA) and after a couple hundred miles the clutch stopped engaging and everything just basically was completely ****ed.

I decided to drop the transmission only to find it would not come off.. like any more than a half inch. I even tried using a comealong with a chain hooked from my tow hook to the transmission. Still nothing

Finally I said **** it and busted out the sawzall and oxy acetalyene and went to town.

When I finally got the transmission out, I found that it was the pilot bearing frozen on the input shaft.

Looking back, I don't think I put grease on the end of the input shaft.. could that have done it? I just really don't want to repeat this problem again because trannys aren't that cheap.

yeah, you NEED lithium grease for that, i must have used half the tube just to make sure the pb and shaft were well lubricated. so sorry to see that, ouch.

yes grease was probably the culprit. did you manage to damage the actual transmission or only the bellhousing..cause to be honest with you. all you would need to do is replace the input shaft and cover the hole on the housing and reuse it

I did my transmission recently and I used mobil-1 synthetic grease, it was only rated to 350degrees; your making me think I should have used some high temp grease instead, something rated to 550+.

ok.. well I didn't use any..... so that probably f'ed me. the ****ty part about it was I got rid of a spare transmission 2 weeks before this... but ya.. I could just change input shafts and bellhousings.. o well. I'll put it all back together over thanksgiving.. I'll let you all know how it goes.

if anything.. having the engine and transmission out would have made it even harder... the comealong pulled so hard on the transmission that the whole chassis flexed.. There really was no other way about it.

I was under the impression that if the pilot bearing was of the lead impregnated bronze variety you didn't need to use grease. And that the use of grease actualy hinders the bearings effectiveness.

holy crap that is the coolest thing i have seen in a long time. my hat is off to you and your awesome transmission pulling skills sire.

also, i never used any grease when i did my clutch several years back, and it has never given me a problem. in fact, i have disassembled and re-assembled the clutch/transmission several times since then and never used any grease.

Was the motor originally an auto because that looks like a torque converter bushing that is pressed into the crank. You were suppose to take that off and not use it.

Actually, NO, grease or lack of it did not do that to your pilot bearing. That bearing is in the wrong place for a manual transmission, its to far up on the input shaft.

Yeah you were suppose to pull the automatic torque converter bushing out. I'm not even sure how you even squeezed the input shaft through there. You should get a hold of a manual one and put it on there.

I must say that you have huge balls to take a sawzall to your transmission's bell housing! I cringe at the idea of it. Good thing there's no shortage of bell housings.
