Pilot Bushing

I knew it was too good to be true! Zero problems yesterday getting the old T15 out in the limited time I had to work on the Jeep.
Today was another story.
Three frozen bolts on the clutch (two twisted off, one I had to cut off)! Three flywheel bolts were loose and one so frozen I feared I'd break it off as well! Inside the bell housing I found many small fragments of brass that turned out to be fragments of my Pilot bushing.
All that is left of the bushing is the sleeve that contacted the transmission shaft and it is stuck into the crank tight enough that the old tricks (TP / grease) have not budged it.
Any tricks to get it out? I'd like to get it out without rebuilding my engine!
Thanks, Jeff

 

I had a control arm bushing do this and thinned it out with my dremel tool until the rest peeled out. The vibration from the dremel semed to help loosen it up too I think. Sometimes heat from a mapgas torch (about $25 at Lowes) does the trick, too. PB Blaster is my fave lubricant.

 

A hammer and small chisel should do the trick.

 

Anyone know (off the top of your head) the diameter of the input shaft for a T15?
I think I'll try cutting threads in the bushing, then screw a bolt in and see if it won't displace it

 

Have you tried a pilot bushing puller? I am assuming that what is left of your bushing is just kind of seized to your crank? If you haven't used a puller, it has two prongs on the end that push outward when a nut is srewed on the end of the puller. Then there is a slide hammer on the other end that you slide and the concussion pulls the bushing out. I have had good luck with them but never had a bushing stuck that tight. You might want to soak your bushing in penetrating oil for a few days first.

BTW I rented the puller from the auto parts store the last time I used it.

 

I just pulled my bushing out less than an hour ago. What a coincidence. I was having a similar problem. I ended up using a big tap. Twisted until the tap bottomed out against the crank, then I just held the main pulley and kept on turning - pushed it right out.

Funny . . . I just picked up a tap from the machine shop that is resurfacing my flywheel.
How did you keep the crank from turning while you tapped the bushing?

I put a ratchet on it. It wasn't hard to hold still, and the bushing came out fairly easily, too. Mine was on the hoist when I did it, so it was easy to reach both sides at once. If you've got some accessories hooked up, it might stay in place for you.

 

I got a chance to work on the pilot bushing for a few minutes last night (all it took, really).
Turns out I didn't need the bolt, nor did I need to stop the engine from turning. The bushing is very soft (this one may have been even softer than a healthy new one).
The only problem I had was that the bushing crumbled, not allowing the tap to cut threads, for the first few millimeters. Once I got back away from the damaged edge the tap caught hold. As the tap met the bottom of the cavity the bushing just threaded up the tap and out of the crank.
Sorry, no action shots but here is the end product.

I hope that's not one of your wife's dishtowels

 

Surgical (Huck) towel.
My life is full of them.
They work great for everything from drying dishes to mopping up what might spill at surgery. Oh . . . and they make a dandy shop towel.
These are made in China and are cheap (MD surgeons throw them away!) We buy "open-unused" by the pound.
