Mazdatrix came out with a tool for installing the pilot bearing as well.

 

Cool, thanks for the info. Don't ya love how versitle sockets are?

 

idk about all you guys but harbor freight sells a blind hole bearing puller...works AWESOME, best $40 i ever spent basically the same as the mazda tool only not as compact ...

enjoy

 

quick trick i use to get the new bearing in....heat the end of the eccentric shaft with a torch to expand the metal...then do work and install the bearing...obviously you don't want the end to be blazing hot but enough so that you can get the bearing in a little easier...now is the time to install a new rear main seal and transmission front/rear seals....they are cheap enough you might as well do it

 

Autozone Puller failed on me miserably, worked at it for 2 hours.

Then I tried this.

And it took it right out. I had to buy the machine screw but cheaper than a pilot bearing puller that I probably wouldn't use too often.

 

I tried Autozone's puller before (the Free Loan a Tool one right?) , their puller was too big for the bearing.

Mazda all the way

 

Most of the tools that auto parts stores lend out are worn. If the pilot bearing pullers jaws are worn, then it will be a ***** to use.

Honestly I've Dremeled them out and used the bearing puller. After using a NEW bearing puller, I will never use the Dremel again. The Dremel is fine to remove a damaged bearing outside of the car, but when the engine is in the car, the proper tool is the only way to go.

Just tap the new bearing in place with a hammer and the appropriately sized socket. Same with the seal. Lube everything well in bearing grease first and make sure the bore doesn't have any burs.

 

I broke down and bought the tool, I was doing this so often I figured it was worth it. I think it was $75 and I've ended up having at least 5 people borrow it from me.

Buy one and be instantly popular with your local RX-7 crowd!
