I lost my clutch recently- great storey. After pulling the transmission for the clutch and flywheel swap, I wiggled my input shaft... and sobbed a bit. It was wiggly. so its apart on my bench vice. Now..
Q1= is it a 150 or 151? the door says 150, however I am not knowing.
Q2= is the rebuild kits the same for both?
Q3= the outer race of input bearing is spinning in the housing. This is not a good sign for industrial gearbox's, I cant see it being good for this one. Is this box a lost cause??? I need to know before I order $900 worth of bearings, seals, and sync's.

 

Without seeing it in person and feeling how loose it is... it's not unusual for a trans input shaft to wiggle around some. It's a shaft that is normally supported by bearings on both ends - one bearing on the front end of the trans case, and the pilot bearing in the end of the crank. With the trans out, one of those bearings isn't in place.

Wait, never mind, I just read Q3. Lol, that's not good.

 

R150F.
