I am doing some work on the ex-Ryan Covalt now Lou Madsen 62 Valiant. I needed to look at the clutch after slipping it on my last drag strip outing. In the process I noticed that the input shaft I use as a pilot for the clutch disc had too much play in the pilot bushing. Sure enough the bushing had worn considerably, why is another issue. I tried to use a slide hammer with an end that looks like a claw which only catches one side of the bushing. I have used this method before successfully. Apparently because the bushing has worn thin the puller didn't grab good enough for the slide hammer to work. I know there are other types of pullers including one that expands all the way around and would almost surely work. Have any of you had any experience with other types of pullers? I also watched a U-Tube video where they kept pounding bread into the bearing until it forced it out of the hole. Have any of you ever tried that? How about trying to pound an awl between the bearing and the hole to fracture it? Any ideas would be welcome.

Not bread but I have heard of filling the hole half full of grease and then whacking it with an old input shaft or bolt that size and it would force it out.

An old guy told me to pack it with grease, then wrap a rag around the end of a dowel, and wack the dowel with a BFH. the hydraulics may force the bushing out of the hole. Similar to bread. It worked for me once.

Any chance you have a tap and bolt big enough?
Thread it and screw in the bolt - when it bottoms in the pocket it should begin to draw it out.
Or if the bolt is long enough use a nut and socket to pull it.

Thanks for doing this work, Seymour. Nice to chat with you on Friday about the car.

I have heard about the grease trick too, but have never done it.

Yet another option is to buy the retrofit roller bearing that presses into the torque converter pocket and just leave the old pilot in there. I could have one shipped to you.

This design looks like it would be much easier to pull and replace too...

Slant on,

Lou

Just go to any "good" parts store for that bearing.
Ask for pilot bearing for a 1992 dodge D-150 with a 3.9 engine, and standard trans. Should be under $15 and no shipping

The bearing that goes into the crank pocket would be nice but all my stuff is small register and I doubt anyone makes that one. I'll try the bread or grease deal when it warms up, today we are looking at a high of 42 with rain.

The grease method works fine. The closer the fit of the driver, the better. Less leakage between the pilot bearing and the driver.

Someone finally noticed... Thanks, Dennis! I am looking forward to being a true Exner geek. Been wanting one for at least 20 yrs (after racing Magnante's toad).

Without knowing what kind of bread you are going to use, it's hard to know if that method will work or not. It might be best to use a plain white bread and some smooth (not chunky) peanut butter in place of grease, plus a dab of jelly.

Anyway...you have to be careful not to go too far but I'd use a die grinder to cut a single longitudinal 'trough' down the bushing. Once the wall thickness gets 'thin', the bushing will give up and slide out easily.

I have never used the grease method, but seems sound in principle.. I have pumped brake calipers full of grease to pop out the frozen piston. Works fine. I have also used the grinder/ cutter method to thin the wall of parts specifically on exhausts where I wanted to say keep a convertor or muffler but needed to replace the pipe at the slip joint.


Both can wok well.

If the pilot bushing is the typical cintered bronze style, you can use a tap to thread into the hole. Once it bottoms out against the inside of the crank, you can continue to turn the tap and it will act as a jackscrew and force the bushing out. Just an FYI, on most Chevy's you can use a 7/8 tap and works really good. Thread pitch isn't really important.
