Hello all,

Today I found my front wheels aren't spinning. I took apart the front covers and found when I move the belt, the gears inside don't seem "attached" to the axles and make them spin at the same time. I'm not sure what's wrong. Can anyone give any advice?

I'd say you probably stripped the differential gears.

Which model? Are the pins even in the outdrives? Lock nut has lost it's gripping power...diff too loose?

I didn't strip anything. I found it wasn't spinning with the belt drive so took apart the cover to check things out.

Ah yes loose diff seems like the cause. I tightened it, seemed it fixed the problem but after a quick spin it came loose again. Will look deeper into it. Cheers!

The nylon part of the lock nut, that is used to keep diff/thrust bearing tight, is probably worn out. They generally have a long life span. I replace the diff lock nut after a rebuild or two. In a racing situation, I'd opt to change the nut every diff rebuild. Also, when assembling ball diffs, after pushing the thrust bolt/ screw through the center of diff, I like to be sure the thrust bolt/screw is free from any grease that may have got on the threads while building the thrust bearing.
