hope i don't bore you all but..............

AA tells me i need another pilot bearing/bushing. that i can believe because the tranny shafts are obviously different size ends- 3550 is larger.

i haven't taken the old pilot out nor have i got the new one yet BUT when i take out the old one there is no way gonna be enough room to stuff in another bushing and the larger tranny shaft.

it appears that there may be a bushing that the peugeot bearing is pressed in. can this be? i put the pilot bearing in my 4.2 when i did a clutch job before.

so............if i explained this right, are there two bearings/bushings to come out of the 4.2 crank? there must be cause this swap is supposed to work according to AA and i was thinking someone else has taken this road before me.

thanks
steve

The pilot bushing is different than the pilot bearing. The pilot bushing will look like "doughnut" approximately 1.5"- 2.0" in diameter. It has a hole in the middle that the trans. input shaft will fit into. It does not fit in the small opening of the crank but at the wide part of the crank at the "mouth". You will need a hammer and a piece of wood or something that is soft to drive it in. Would not hurt to clean crank with heavy sandpaper. Hope this helps.....

Steve, as was mentioned, the pilot bushing is a donut shaped, soft metal piece that goes into the end of the crank, and the pilot bushing fits into it. When I did my auto tranny swap, I had to remove the pilot bushing. I used an air chisel to cut in in two places and then it popped right out. Another person, who recently did an auto tranny swap, drilled it (with a drill bit a little smaller in diameter than the thinkness of the bushing) in two spots and then cold chiseled it out.

Here are some photos of mine being removed:

You can see it in the center here. It's already been cut:

Here, it's almost popped out:

And here's what it looks like removed:

i got the little pilot bearing(needle bearings) out that i replaced when i did the clutch job some time ago. there is still a small diameter "bushing", approx 3/4" dia in the end of the crank. i don't see any lrge diameter soft material to come out. i wish i could post a pic on this board. i have a pic i can email you.http://bbs.off-road.com/ubbthreads/download.php?Number=953894


ok, maybe i found a way to post a pic- did it work?

Steve, I have two lines on the photo of yours, that I'm attaching to this.
That "small diameter bushing" that you are calling it, ("A" on the lines that I drew), is just part of the pilot bearing itself.
The part that I have maked "B" is the bushing, which will have to be removed. It's in there so tightly that it appears to be the end of the crankshaft itself, but it's not. That's the pilot bushing. You'll see when you get the one from AA.
That "hole in the crank" that you mic'ed is not "a hole in the crank" ;)
That's the hole in the pilot bushing.

thanks fred

Yup, it is big. See the photo that I posted (above) where I have it out, in two pieces and am holding one half of it ;)
When we were doing the auto tranny swap, I found it hard to believe, for a little while, that it wasn't the end of the crank shaft, but it's not ;)

i'm thinking of using my sawzall with a fine tooth blade to cut it out with. make a few cuts and then whack it out. i would imagine even if i make a mistake and cut a little into the crank it should be ok.

I'ld go the drill routine, if you don't have an air chisel. Drill two holes in it, 180* apart. Use a bit that's a little smaller diameter than the thickness of it. After the two holes are drilled a wack ot two with a cold chisel should split it and then it'll pop out.
I don't see how I could have possibly gotten a sawzall up in their on mine. Simply no room to work, no room for the blade to move.

yeah drilling should work but start with a small bit and work up to the size hole you need to waste the bushing. seems plenty of room for a sawzall- i will try it. see which method works best. seems the blade will have room to move and i surely have enough room to sit up under the jeep and work.

yes i have an air chisel but i never use it- doesn't work good in my opinion. it just sits in the tool box and collects dust.
