[Supras] Tip for changing pilot bearing on R154 MT

[Rich Peacock]

Good tip!

I use a slight variation...
Instead of grease, use playdough or flour/water mixed.  It usually comes 
out clean.
I use an old stock head bolt instead of the socket extension.  Everyone 
uses ARP's anyway, right???  ;o)

Harbor freight sells a very cool pilot bearing puller for cheap.  You 
will have to grind the hooks down to fit inside a 7M pilot bearing, but 
it worked absolutely great on a Jeep Wrangler I just replaced a clutch in.

I tried to fabrical a tool that is shaped like a hook using an alen wrench and then used the back side of a hammer to pull it, but the bearing didn't budge.  In my desperation, I got online and googled "Pilot Bearing Puller" and came a cross a thread that gave me the answer, and the best part is, I had all the necessary tools right there in my garage.  Here is all you need:

> 3- 1/4" extension (a short one is fine).

> 3- with the socket on the extension, pack the socket with grease.
> 4- now insert the socket through the bearing and hit it the extension with the hammer.
> 5- the bearing will begin to move by the hydraulic force from the grease.  It'll move 1/16" to 1/8".
> 6- Refill the cavity with grease, as the movement of the bearing creates more space for the grease to fill.
> 7- Repeat steps (4 to 6) three or four times and the bearing will be completely out!
