Fellas- I plan on using a 292 block with 312 crank, rods, and pistons in a car originally equipped with a 292/ 3 speed manual trans. I will need to retain the 3 speed. Is there going to be any problem as far as the 312 crank and the need for a pilot bushing are concerned? (he asks AFTER the short block is assembled)... Thanks /Duck

BOO- YA!!!

The pilot bore is the same size on 272,292 and 312 whether crankshaft was used on automatics or standard transmissions.

you will have to buy a bushing specific to fit a Y-block as the pilot holes in the crankshafts are different sized than a FE or 302 engine.

When you get the new bushing clean the pilot hole in the crankshaft of all debris and take some fine emery cloth to remove any rust. It should be relatively clean as the torque converter pilot fits in the same hole. Then using a bushing driver if you have one or use a large socket as a bushing driver that is about the same OD as the bushing, start the bushing in place by hand, then place the socket against the bushing then tap bushing in place gently with a hammer, watch that bushing is going in straight and not being cocked or crooked as you could damage the bushing.

Thank you very much Marv- I really appreciate your reply- /Duck

BOO- YA!!!

My local NAPA also sells a pilot bearing as an alternative to the bushing.

Is the transmission snout that goes into the pilot bushing/bearing the same diameter on a regular Ford 3 speed as it is on a T-85? Also how does one get the old bushing/bearing out of the crankshaft?

EJ:

The pilot diameters for passenger cars are the same.  To get the old bushing out, I take a shaft that is a slip fit into the hole.  Metal, plastic, or wood, doesn't matter.  Pump the cavity full of grease, level with the outboard face of the bushing.  Tap the shaft into the grease, and the bushing will move out a little.  Add more grease, tap, more grease, tap until the bushing is out.  There is also a puller made for this, probably a Ford service tool from the past.  I saw one once.

A socket works great for the procedure John described. Just find one that fits as tight as possible. Stuff the socket with a paper towel first so it doesn't get full of grease.

Thanks guys, I had heard something about that grease thing but had forgot where I saw it. Back in the day I put a T-10 where a T-85 was but don't remember if I changed it or not. I've got a T-89 from a guy up in GA and at the time I thought it was a T-85. He's coming back to Moultrie next month and he's got a T-85 out of a '64 Ford and I'm gonna try to swap him this T-89 back for that T-85.

pilot bearing puller from NAPA # BK.700-2476  which is manufactured by BALKAMP and it works.
