Pilot bearing size

Hi,

If it is.044" difference, that is basically 3/64". In my mind, that sounds correct. If you divide it by 2 since it is round, that leaves (3/128") play on each side. That's roughly.023" which really isn't too much. I feel it should be fine.

Let me know if you have other questions.

Just to confirm, is this a 289 engine?

If so, here is a link to the correct bearing. It shows the input shaft diameter is .672" so that will give you a reference point to start. The outside diameter should be about 1.380". It is ok if this is a couple thousandths difference because the crank is going to wear slightly so it could be larger.

The bearing is going to be slightly smaller, but you should have to press it in or use a block of wood and hammer to get the bearing to seat. However, they are removable so they are not to be so tight that you cannot remove them. .044" of an inch does not sound like too much but using the above link as a starting point should give us a good idea.
