The dremel is fast, but there is a risk of cutting into the eccentric shaft...

You could also use the TP method!

the engine bolts... the one that sits closest to the slave cylinder on the top or the engine..its about 4 inches long... you have removed it already in removing your transmission... stick the nut in the hole and slightly turn it cockeyed locking it inside the pilot bearing... thread the bolt into the cockeyed nut inside of the bearing.. as you ratchet it and the nut slowly slides out... so does the pilot bearing. Trust me, crap on the pilot bearing removal tool. I have one too. never used it, give me your address and ill send the pos to you.

We just dremmeled and chiseled one that had come apart out of my tan 84 GSL this week, it had pretty much become one with the eccentric shaft. I was a little worried about beating and drilling on the eccentric shaft, not having done it before, but the blind end shaft turned out clean and the new bearing fit in nice and snug. Getting that bearing out took about 3 hours but it seemed like 8. Will the removal tool pull the bearing out after the front of the bearing casing has disintegrated and all the rollers have fallen out?

Talking Puller

Damn straight there sparky, that is what i use. Never had a bearing take more than 30 seconds to come out. As far as the other pullers the one that is attached to a slide hammer and expands also when you tighten it is also very effective. If you get one that sets against the surface of the flywheel but you find there is not enought travel on the bolt take 2 sockets on either side to allow the puller to leverage more against the flywheel surface. I had to do this once when i rented a puller after i used the sockets it came out perfectly.

I just tried it...didn't work. That nut is shouldered and does not lock itself into the pilot bearing.

What they say about the snap-on is dead-on. I was spoiled by one, my neighbor had his handy the first two times I did the job, and I've had to go without one since. Even with the extra work, I can't seem to talk myself into spending that much on a specialized tool.

Is 12mm small enough to get past the bearing, or is that where grinding the puller teeth down comes into play? Would this style of puller work, or is the slide-hammer type--

When we did mine last week, the bearing was broken and all the rollers had fallen out, leaving the thin metal sleave tight against the eccentric shaft. I don't think any kind of puller could have gotten this out because there wan't enough left to grab onto. We ended up grinding down a half inch drill bit (the only thing hard enough to stand up to the hardened bearing metal) at a sharp angle to use as a chisle to get under the lip of the bracket sleave and wacked the thing out. This took some time but knowing how to do it would make it easier if I have to do this again. But if the bearing is still intact, I'd find a puller.

The last one I did was like this, It also had the Trans locked in. I used the AutoZone Slide hammer puller and it came out with out much fuss.

Pilot bearings are hard to lube so you better get it right when you put it in. What's the best lube?

i used the pilot bearing tool and slide hammer from AutoZone, too. it took me about 5 minutes to get it out. the key is eyeballing a straight line. i was so impressed with the results that i decided to forget about buying the Mazdatrix tool in favor of just buying tools like what i rented from AutoZone (if they're less expensive), but we'll see ...

i would like to try the TP-method one of these days, just *****-n-giggles, but it should be a while before i have to do my next pilot bearing.

i just used regular grease. don't just GLOP it on though. i spread a thin coating over the needles in it with my finger and then installed the bearing.
