Hello, this is my first transmission rebuild. It was off a 1972 Raider 12 so I thought it had a limited slip differential and took it apart to see why both wheels were not grabbing. It turns out that it has the 8 pinion differential. There is a damaged bearing, I destroyed the plug for the detent passage and some of the gears have wear but it doesn't look bad to me.
My questions are:
1 - If the other bearings are complete with no damage do I leave them or is there a way to test the amount of wear to indicate whether they should be replaced or not?
2 - Where do I get a new 1533 bearing, plug for detent hole, oil seals and gasket and how do I remove the bearing?
3 - The gear pictured was the gear with the most wear. Is that perfectly fine to use?
4 - I'm guessing that it is a 5091 transmission or a 5073 with the differential replaced. Is there a way to tell what it is for ordering proper parts or are parts going to be the same?
Thanks, Tim
