Alright, I realize this may be a <IMG SRC="smilies/rainbow.gif" border="0"> question, but I'm curious how you get the pilot bushing in the crankcase. I have a 400 chevy, i'm guessing just take a BFH and force it in, but don't want it to go in to far or does that matter, i'm running a Np435 behing it. Any help is great, flame if ya must <IMG SRC="smilies/thefinger.gif" border="0">

I used a block of wood and a hammer to tap it in. Its not that hard. I went all the way to the back of the crank when I tapped mine in. It wasnt exactly a stock replacement application either. Pilot bushings aren't all that critical imo.

I would also recommend using a block of wood to drive it in, don't wanna screw up the center hole so that the input shaft of the tranny doesn't go in smoothly. Just hammer it in there until it's flush with the end of the crank. If you use the block of wood, that should be easy enough.

brass bushing or a bearing, if its the bushing, throw it away and try and find a bearing for it

or, yes use the hammer and some wood to drive the slut in, i normaly put a little loctight on the OUTSIDE of the bushing to help to keep it from spining

The bearings (non bushings) Have more moving parts therefore have a better chance of failure. I would not use them. This is my opinion and may not be taken as welldoneman's would.

Put the bushing in the freezer for a couple hours and it'll shrink slightly and go in easier. But don't play with it when you take it out, it'll warm and grow <IMG SRC="smilies/biggrin.gif" border="0">

Be sure to check the bushing and make sure it fits around your input shaft before you smach it in. I have seen bearings not fit the input shaft before, and the wrong time to find this out is when you are muscling that tranny around.

Good luck

That is a bad opinion, the pilot bearing is very important it keeps the input shaft from flexing under stress. Flex in the input shaft= breaking of gears.

Put it in the freezer for a couple of hours and if you do not have a pilot bearing driver, I use a block of wood or a piece of wooden hanger rod. Drive it home until it seats

Working on electromechanical devices with high speed rollers that use bearings, and bushings, has taught me two things.

1)Bearings Fail Eventually.
2)Bushings Wear, without catstrophic failure.(usually)

My observation.

Personally I would go with the bushing rather than the bearing. Just a preference.

The reason i like the bearing is i have seen a LOT of bushing sease then weld them selfs to the input shaft (makeing shifting really fun), most bering start to just make noise on you i have yet to see one explode
