Chain case

[sneakattak88]

Doing bearings and gears in my Nytro next week, is the chain case similar to the Apex? If so I'm good to go, if not i will buy the service book.

Simular, but different, I would say if you are comfortable with the Apex, you will be fine with the Nytro. Just take pics, make note of spring and spacer locations as you remove things and you'll be fine. Don't be surprised when you find a broken drive shaft bolt (bottom gear bolt) as it seems to be common with the Nytro, mine never snapped but many have. If you are doing the left-side (speedo) bearing, which you may as well if not, be sure to complete the chain-case side assemble and tighten the gear bolt before tightening the set screws (2) on the left-side bearing as this reduces the side load on the bearings.
