Pilot Bearing Removal

vex · 04-03-2009, 05:34 PM

I'm using the Advance Pilot Bearing Removal Tool, with little success. Does anyone have a sure fire way of removing the bearing? I do have a slide hammer, but I do not have the attachment for the pilot bearing. Any suggestions?

i broke every loaner tool i could get my hands on. broke Harbor Frieght's puller too.
I had to get a blind bearing puller from a motorcycle tool supply shop.
it was a $120 kit, but it was pretty much my last resort.

the collets are pretty much invincible, unlike the two little L's in the loaner kits.
i used a bridge puller, not the slide hammer.

The mechanics I've talked to have told me to just break the bearing with a chisel and pull it out that way. Should be fun.

ohh lol this isnt v8rx7forum..
the grease pack method will probably work best. pack a bunch of grease into the pilot bearing hole, until its good an full. then find a dowel that fits nicely into the hole, and hammer it. if you have the right size dowel, hydrolic pressure will pop the bearing out.

LS1's cant do this cuz theres a freeze plug back there. i highly doubt rotaries have the same problem.

Please don't use the chisel method, too easy to muck up the e shaft. Cost this one guy a motor job when he did his own clutch to save a buck. He wondered why it was making so much noise after he got it back together. The bearing fell out when we pulled the gear box. But the seal was still in the shaft. He said it took him 3 hours to get the bearing out. Saving 200 cost him 2000. (this was a long time ago)
I haven't seen any of the other procedures to work well with a rotary. Afraid the best is the mazda puller.

Give Dan or Ray a call and save yourself a lot of grief it is well worth the money.

Tried the chisel once when my puller had a broken collet finger which happened after I don't how many bearing pulls. After 2 1/2 hours of work to not damage the shaft I went to one of my buddies that still worked at mazda and borrowed their tool and ordered 2 collets at the same time. Wore out 1 collet in 30+ years one of those I ordered is starting to get a little shaky now. When you get one it will last you a life time.

the grease method is the best way it never fails or destroys

Fidelity101 · 04-04-2009, 09:07 PM

ive used a die grinder before.

I like the grease method the best, but if the bearing is severly damaged you might end up using the die grinder or a puller. If you are careful with the die grinder, it does a good job. I have never had success with a puller if the grease trick failed (although I have never used the mazda puller either).

ended up using a die grinder and the puller. worked quite well

I rented the autobone puller for $25 and just never gave it back. I had to grind the fingers down slightly though and weld a nut onto the collet though becuase the slide hammers threads were different. Works great though.

I've never had any luck with the grease method.

Of note though, if the bearing is pressed in too far, doesn't matter which tool you use, you won't be able to get it out if you can't grab onto anything
