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 -- -- -- Please address private email -- email of interest to only one person -- directly to that person.
