Thread: vibration

Tweet

unhooked the converter vibration gone. Must have had to shim conv to flywheel when i installed the trans, took 1 shim out of all three bolts in the conv and vibration disappeared. Runs down hiway pretty smooth, now if I can get the idle in gear solved I'll be happy, hope the new intake cures that

Why did the converter need shims???

the conv wouldnt go all the in the crank, it is a vega stall conv, dont know why it wont go all the way in maybe should grind it to fit?

shouldn't need no shims. how thick of skim are you running now? thats a good way to make it vibrate.

the shims are about 3/32, have to shim otherwise will warp flywheel flexplate

it needs to go up without shims. push the conv. as far forward as it will go, and then tap and turn it and see if it will go in a little more. don't hit it hard. you sure there is no pilot bearing still in the end of crankshaft? how long has those shims been in there?

I will try again tommorow. they have been there for ten yrs, I dont know why it didnt vibrate before, all the bolts were still tight. I had about 1/8 " shim in there took that out and pushed the conv all the way to the crank it went in but not far enough to mate with the flywheel. measured the distance (well I try and error with shims) and shimed it and put conv bolts back in, took for a drive and no vibration. I know thats not the way it is suppose to work but until I remove the tranny to figure out whats up it will do for now beings the shims have been there for long, I will take your advise and try to tap the conv in. I am just about positive there was no pilot shaft bearing in there. thanks for the help and will post tomorrow on results.
