Awesome Pilot Bearing Puller (image intense)
Check it out......
After going to Lowes, Harbor Freight, and every "Auto Parts" place in town, I finally decided I could make a bearing puller a lot faster (and cheaper) than I could find one to buy.
This little bad boy popped that sucker out like a cork
.
I used a decent sized square bolt, drilled a hole through the metal shims to attach a carriage bolt, and ground the head of the carriage bolt to where it just fit through the pilot bearing. I used a nut to grip the pilot bearing and turned the two square bolt nuts to apply force evenly on either side until the bearing popped out. Piece of cake

Very ingenious. Thanks.
Any chance of another pic - with a ruler underneath?
Am I right that the pull is just slightly off-center because the carriage-bolt lip has to fit through the bearing and then move over? Is that the reason for the nut on the carriage bolt, to keep the pull on the bearing as square as possible?

Yes, the pull is slightly off-center and the nut keeps the pull on the bearing as square as possible, plus it keeps the carraige bolt from slipping; that way you don't have to have your other hand up there trying to use a screwdriver or vice grips to keep the carraige bolt wedged into place. The nut doesn't have to be tightened much.
Step 1. Put the carraige bolt and nut on the bearing.
Step 2. Slide the square bolt on and spin the other nut on to hold it.
Step 3. Turn the square bolt nuts, alternating sides, until the bearing pops out.
When the bearing gets close to popping out, be sure to hold the square bolt; otherwise it may surprise you and land on your face
like it almost did mine.

Looks neat!
I bought the Harbour Freight pilot bearing puller after studying the specs. When I got it home I found the three "prongs" were too big to fit through the pilot bearing (the specs were wrong), however it could still be persuaded to work with just two and the other folded out of the way.

Thanks for the compliments everyone!
I agree, the Harbour Freight puller (around $16) states it will fit a 1/2" inner diameter, which should just about fit the 928 bearing. There is no way the HF puller even comes close to fitting.
Heinrich, if your actually going to need one soon, I'll toss this in the mail and send it to you.

John,
Great piece of problem solving. When my pilot bearing was toast I had simular ideas but couldn't visualize in my head what you could and made real. Congrats!!!
Just put a Sean Bearing Puller on ebay or, $150 bucks on 928 int! and collect the royalties.
