Pilot Bearing...
I sent my flywheel to a machine shop to be resurfaced ('91 Explorer 2WD). When I went to install the new pilot bearing, it wouldn't fit because the hole in the flywheel is too large. The bearring does fit the shaft on the tranny.
Is there a "bushing" that the bearing rides in or do you think they may have given me the wrong flywheel? I checked the bearings from 3 different sources and they all came up the same size.
Thanks for your help-
Joe

Yes, the pilot bearing needs to be installed into the "adapter" that was pulled out with the old pilot bearing. It may be at the machine shop because it was left in and they would have to remove it to set it up on the resurfacing machine. You might hurry and give them a call before they throw it out. otherwise, you will have to buy a new part to replace the missing one.

Interesting! I should have asked a question HERE!
Just spent quite a while last month fighting a cooked pilot bearing in my 96 Expy. The Haynes manual gave me impression bearing was in the crankshaft (which I've never seen before...) . If I'd known was actually removable with the flywheel, would have pulled it off and been alot happier!
Nothing would pull it out, the outer case-hardening was severely "heat-crazed" and gripping the bore like snake-skin. I eventually cut a grove in the outer race with a jewelers' file, and then it popped out nicely.
SO... is the adapter collar holding the pilot actually pressed into the FLYWHEEL or the end of the Crankshaft?????
Thanks

It's in the flywheel itself. Funny thing- this is the first time I've ever seen it in the flywheel. I've always seen them in the crank.
Thankfully the machine shop that resurfaced the flywheel still had the collar. The "machinist" (hillbilly) thought that the whole thing was the bearing so he tried to lecture me how a real mechanic would change the bearing out when doing the clutch job. So I quickly interupted and began to lecture him how a real machinist would be able to tell a simple bearing from a bearing within a collar that was not disposable. Then the owner stepped in to back me up. I still think I'm going to avoid doing anymore business with them if that's the kind of people they are going to have on staff. What the heck has happened to good customer service?
Anybody out there in the Ft. Worth area that knows of a good machine shop in town give a shout out. I'm going to need some work done on an engine for a Jeepster.

Guess what you are used to, All 4 of my IH's (binders and scouts) have them in the fly, as did my GTO and a Triumph TR4. This was my first exposure to Ford, and the Haynes manual says (p 8-5) "...needle roller type bearing which is pressed into the rear of the crankshaft." The illustration shows the adapter collar, but also says crankshaft.
Just shows you can't believe all you read, eh?
Good luck finding a new machine shop. Maybe now you know the manager, you should stick there? Might get you extra quality... or not... who knows?
