How to determine???

[FMS88]

The 1.25” bearing is probably the pilot bearing that fits inside the center of the flywheel and supports the front end of the input shaft. Definitely replace it with a sealed bearing. Don’t use a bearing with metal shielding. They don’t seal as well against water and dirt. I’ve had two metal shielded bearings rust and seize which ruined the input shaft.

I think you are right. I was thinking I needed larger bearing for some reason.

IS THERE ANYTHING I SHOULD KNOW BEFORE I DISCONNECT THE TRANS? I have it in 2nd gear as recommended in the FSM. I'm not going to drain it.
