08 nytro chain case help

Chaincase

Hey Dave,

1. Make sure you have a washer on the inside of the Reverse Driven Gear nd one on the outside of the Counter Gear (2 small gears).
2. The washer inside the Reverse Gear Assembly (large bottom gears) could have been bumped out of place and the journal may not be seated all the way in.
3. At the top of the linkage arm is a triangular plate that it attaches to. I have bent mine (don't ask me how) and it made it very hard to get in and out of reverse because the linkage was thrown off. If bent far enough it may cause a noise but only in reverse. I'm pretty sure your linkage could not be off far enough to affect the sled moving forward.
4. If you have it apart grab the actual gear shaft and see if it has any play in it. Your bearings may be damaged casuing the noise.
5. Make sure your thrust washers are bowed out away from the driven gear (top one). Also make sure you have the collar with the grove around the middle of in on the inside of the driven gear. If any of the collars are installed incorrectly it will cause the brake disk to stick and the jack shaft as well.
6. After all that it could be as simple as your chain is too tight or to loose. To loose and it will slap against the chain case cover right behind the guard by the plate that is attached to the Reverse Driven Gear shaft. If it it too tight the noise could be the chain stretching over the gears and the excess friction from this. I always back the tension lock nut way off then tighten the adjuster bolt in very snug with a wrench to get any slop out that I would miss doing it by hand. Then I back it off and tighten the bolt by hand until it is finger tight, then I go 1/4 turn with a wrench. Tighten the lock nut and your good.

Hoep this helps if you have not figured it out yet. If you did figure it out post up what the problem was.
