Re: Tip on pilot bearing conversion

Just something I picked up about cranks and pilot bushings. Learned the hard way that some cranks are drilled but not reamed for a bushing. NAPA sells a bushing that is undersize for a drilled and not reamed pilot hole. Tha bushing is 615-1099 at NAPA.

Subject: Tip on pilot bearing conversion

The pilot bearing conversion is for putting a 833 four speed behind a
engine that the crank is not drilled for a pilot bearing. It is a
pilot bearing in a bushing that fits inside of the tork converter
snout register. They can be either the sintered bronze Pilot bearing
or a needle bearing pilot. That moves the pilot bearing location
closer to the clutch splines on the tranny input shaft and requires
cutting off a little of the end of the input shaft. Works great----
BUT...Pre fit the new pilot bearing onto the input shaft. It must
slide onto the input shaft all the way up to where the clutch splines
start. Many inputs are slightly larger just ahead of those splines
and will not allow the bearing to go all the way to the clutch
splines. That area must be dressed down on the I .shaft.
I stopped having fun when I installed that heavy SOB and it just
would not go that last 1/2 inch!. I learned long ago not to install
the tranny to belhouse bolts and pull the tranny into
place!........................MO
