Good Morning or evening all:

I did not have to resurface the flywheel because it's in great condition.

But I did the light emery clean-up.

I called every parts store in Eugene,OR and no one had a puller in stock.

To buy one is about $125.

As per last post the Pilot Bearing is in great shape.

Is this delama going to stop my final pain in the ass that is keeping from putting

KickAss machine together????

I have removed the pilot bearing without the tool. You get a sharp awl or thin screwdriver and wedge between the bearing shell and the crank. If you pry the bearing inward it will collapse and you can pull it out. This is not as easy as it sounds. You must be careful not to scar the crank surface or this will cause your new bearing to fail. Also, once you start down this path you have to finish the job because your bearing will be ruined.

What???You use a flatblade and stuff it between the input shaft and bearing and pull outwards or inwards???? https://www.nopistons.com/forums/pub...IR#>/dunno.gif

Cool.Then the replacement bearing just slides in then?

Use a deep socket as close to the size of the bearing as possible to tap it in. The socket will have to be just a hair smaller to fit in the E-shaft without getting stuck. Then tap in the seal the same way. The first one I put in, I did not tap in all the way and kind of fucked it up. Luckily Phinsup told me to use the socket method, and the next time things worked perfectly. :bigok:

Thanks all for the sugestions;

I'm kinda of glad I brought this topic up. It's good to see all the opinions out there.

F.Y.I. I tried the Hammer and Screwdriver trick on a 82 RX-7 about 5 yrs ago and srewed it up so bad I had to go to a machine shop to get a tool that you attach it to a Drill and hone it out.

Don't think I'll try that one again.

Gonna call around today and see if some Tranny Shop in town rents the F.in thing out.

Thanks again

If its any help now, I used a dremel and CAREFULLY cut through the side of the old one and then pulled it out...Then just used a socket to press the new one in.

Well I finally got the damm thing out!

Auto Zone Rents a Pilot Bearing Puller.

What I did was Grind Down The ends to fit and ended up buying the tool for $20.00 U.S.

First strike and it was history. Who-Aah!

The store was not to happy about selling me the tool. Had a rookie behind the counter and

he did not know how much to charge me. So I said, How about 20 bucks. The sucker went for

it!!!!!!!!

Thanks again ALL
