It is best to use a new Circlip when they are removed. When I compared the old and new by putting them on top of each other I could see the old has lost its shape somewhat.

The diagrahm at the right shows the placement of the circlip on the shaft, notice that on the circlip (#2) the one edge is beveled. I could not notice a bevel on mine but yamaha recommends putting it this way if you do find that the circlip has a beveled inside edge

 

Reverse Gear Case placement

Install the Drive Gear 1 (reverse counter gear) and shaft into its bore in the case. You will have to pull the Drive axle out slightly to clear the gear.

Make sure it seated fully, you may have to turn the shaft to get it to drop in since it is "keyed" to only fit one way

Make sure the oil jet holes are directed toward the drive axle, this is what lubricates the shift fork journals.
