I am trying to replace my clutch, and it appears I will need to turn the engine over to get to all the bolts. Is there a way to do that without using the starter?

I use a flywheel wrench. It grips the teeth on the flywheel and lets you turn the engine.

readily available - maybe even locally

The hole in some 235 harmonic balancers is squared off, and will accept a 3/4" square drive ratchet or extension for turning the engine, but it might be hard to reach with the engine in the vehicle.

Remove the spark plugs and you should be able to turn it over with the fan blade. It sure makes it easy if one person can turn the fan blade while the other is lining up the pressure plate bolts.

With the spark plugs out, and you are under/behind the flywheel, one person can turn the flywheel with the tool and line up the pressure plate bolts (without moving around very much) - as I dimly recall?

Thanks for the information, I pulled the plugs and was going to have my wife spin the fan blade for me while I was under the truck, but while I was getting all set up under the truck, I learned that I could spin the flywheel by hand (with a rag for protection from the sharp teeth!). Now I have to get the pilot bearing out; I saw a video using bread, so I will try that first. Thanks again to all!

Use a threading tap that will engage the bushing ID (I think it's a 5/8") and just keep turning as it bottoms out against the crankshaft. The bushing will walk right out of the bore following the threads of the tap.

Jerry, I had not thought of that; I made pancakes (we are out of bread) and slowly pounded them in to push the bushing out. It worked okay, just a little difficult on my back under the truck. The tap would have been easier. Which brings up another question: it was a brass bushing that I removed, but bearings came as a replacement for the bushing. Should I reuse the bushing, or go back in with a new bearing? The bushing looks okay, just a little scared up but still snug on the shaft.

Bread???? Did spellcheck change that?
Other than making a sandwich, the only trick I know with bread is holding back a slow drip when soldering copper pipe.

To get a bushing out of a blind hole, you could pack it with grease and tap a close fitting punch/shaft into the hole. The grease should drive it out of the hole. Might be a little messy if the punch to bushing ID is not real close, but wrapping a rag around it should prevent (or at least contain) a grease explosion.

Jerry's trick with a tap should work too, if you have the right size tap.

[on edit] just googled a "bread to remove pilot bearing" video. HUH? who would figure. Basically the same principle as the grease trick, but possibly less messy. I suppose you could use Pla-Doh or any other similar substance as well. Another learning experience.

Bread is cheaper and it is biodegradeable, if either of those things matter.

Kevin stated the flaw in either/all "back pressure" techniques - a really worn (wallowed out) bushing might not allow enough back-pressure to push out the bushing.

I dimly recall once using a pilot bearing/bushing puller (search the Internet), but it must be able to fit in the relatively small hole in the bushing (1/2" - Jerry suggests 5/8"?).

Jerry's tap technique sound real good. If you use that technique, tell us about it.

The bread technique (pancakes) worked real well and was easy to clean up. Which was nice since I was on my back under the truck doing all this. It was a little hard to swing the hammer, but it really did not take much pounding to move the bushing. To finish up, the new clutch is in and the transmission is back in too. Just need to finish up some work on the differential so I can put the shaft back in.

Congratulations, LeeD

I have seen sealed ball bearing pilots run out of lube and disentigrate. It's hard to beat a plain old bronze bushing.

Lee,

There is also a You Tube video out there doing what I think you are going to try with bread. The one I found, and followed, uses small pieces of wet printer paper. Good luck.
