torque converter to crank problem.

so i got the motor and trans nestled down in the elky tonight. all is well and good, if things keep going well should have it back on the road by Monday.

problem is, the "snout" of the torque converter wont go into the hole in the back of the crank. so I cant get the bolts in.

I put the engine/trans in as a unit, as I figured that would be much easier.

trans/converter is an 85is 700r4, engine is a 73ish 350 that until last week was coupled to a stick.

can I pry on the converter to try to get it to pop in the crank snout?
is there something im missing?

I don't normally work on automatics (this is the first one I've ever reinstalled, actually. usually when I pull them out, a manual goes back in. never done the other direction), so I apologize if this is a newbie question.

I did make sure the converter was properly seated in the trans, and before getting the engine/trans mated (did not check after mating) and the converter slid in/out easily still.

what do I need to do? ill be back at the shop about lunchtime tomorrow.

Michael

Don't pry on it. The pilot bearing might be protruding enough to keep the converter snout from seating.

Actually, the std trans pilot bearing must be removed from the end of the crank. For use with an automatic

as mentioned , be careful , check for pilot bushing for manual transmittin in the crank. See my photo:

In this photo is a 350 chevy engine. GM crate engine I put in car 15 yrs ago, with T-350 behind it. Bushing is in far enough in crankshaft so no interference happens. The T-350 was behind a 305 engine for a while, so the T-350 trans has about 120k miles on it.

Point is, there may or may not be interference from the pilot bearing/bushing- so check to see if there's anything sticking out beyond the end of the crank that could keep the converter from seating all the way.

Not saying it might not be a good idea to remove it anyway. Just saying.

The key was. You stated there was a manual trans before. Very few people remember to pull the pilot bearing.

I bought a short bed pickup for very cheap one time. Same problem, but the guy just tightened everything down and couldn't start the engine..
