Well while I`m slowly trying to get it apart, I see some small balls flying out that I failed to see in the manual. lol. They`re the really, really small ones. How in the h*ll are you guys getting these back in? I`m guessing there insnt an easy way, huh? Just the way they went back in. Any tips? Thanks guys
Those are probably the thrust balls for the thrust bearing. If you lose any of them, Kyosho does sell a thrust bearing kit. It's a wear item anyway so you could replace it now while you have it out. Anyway, there are seven of them so make sure you find them all. Their small size make them look tough to put in, but it's actually quite easy.
1. Take the thrust shaft cap screw and put it on the end of your hex driver.
2. Slide on a thrust plate
3. Put a generous amount of black (lithium) grease on the thrust plate where the balls go.
4. Get a toothpick or something small and pointy, dip in black grease, use it to pick up and deposit the balls on the grease on thrust plate. Do so for all seven.
5. Slide on the other thrust plate
6. Slide the outdrive over the thrust assembly.
7. Re-assemble the diff from there.
Make sure you shim your diff according to the manual...even if it feels tight. It will loosen up as it breaks in. Else, you will strip it again very quickly. When done right, I have had these last for a whole season. Also, make sure your slipper is loose enough to protect it in the future.
