I just finished pounding a brass pilot bushing into my crank . It had to sit in the freezer overnight to get it in and now it won't budge further and has about an 1/8 in to go until flush with the crank . Is it in far enough ?

Flush with what part of the crank? Is the bushing bottomed out in the hole? Post a photo if you can.

I think it should be flush with the edge of the hole in the crank ,but it sits up about 1/8 inch . There seems to be a little more depth left in the hole but the bushing won't move now and is beginning to distort .

IMO the only way to be positive, is to mount the bellhousing and measure the distance to the transmission's mounting face, which you can compare to the distance from the face of the transmission to the input shaft bushing surface.

It shouldn't be that hard to install anyway. Stick an input shaft in it and see if it will still slide in the pilot.

looks like I have about 5/8 in and the shaft will only go in about 5/16 so it looks like it will fit . If anything the bushing might be IN too far .

I take it you didn't measure it against the old one for width and depth? I never had to freeze one and they went it fairly easy on an old input shaft. You better be sure before you put it all together.

listen to kermie!.....

My pilot bushing is flat flush with the end of the crank. Don't think it should be sticking out at all.

That definitely isn't right... no freezing or pounding necessary, plus if it is distorted it is no longer a bushing.

If the bushing is not deep enough you could l break the ears off your trans when bolting up. Sonnds like something is not correct.

Also check the archives for which bushings get grease.... some don't depending on what they are made of!

You could tap the pilot bushing with a 5/8 nc tap and jack it out with a bolt. See what the problem is . Chances are the pilot bearing has collapsed. Try the tranny input shaft in the bushing to see if its damaged.

Where did you get this bushing and what is the part number? Perhaps is the wrong one for your crank. An ill fitment can cause a wide range of problems from unexplainable drive line vibrations to clutch chatter to damaging front transmission main shaft gear bearing, to gear clashing when shifting. I think that i would likely start over before moving forward with buttoning it up.

More like a 5/8"-18 tpi fine thread.

Bushing bore is way too big for 11 tpi. Closer to tap drill size for 18 tpi. More thread engagement.

1) You shouldn't have to pound it in
2) It should be flush with the end of the crankshaft
3) If it has begun to distort it is already toast. Take it out and start over with the correct part.

CJS

If your engine was a PG originally, the bushing hole was not reamed at the factory and so that causes a really tight fit that usually will not work. You need a custom size OD bushing.

Frankie the Fink

My bet is with CJS's diagnosis....

Having to freeze a bushing and then pounding it in is certainly not normal.....

Kerrmudgeon

You should take it out and check it anyway. Use the old mechanics trick of packing the hole with heavy grease (wheel bearing) and using an old input shaft or anything of same diameter, start tapping it into the hole, put in more grease as you need it, and amazingly the grease pushes out the bushing. Then get the right one!

i think you have the wrong pilot bearing! should be flush and not that hard to put in! pretty important that its right!!!
