1998 Yamaha Wolverine - Rear Diff Setup

[shelbygt500]

I am working on my nephews 1998 wolverine. I am replacing all the bearings and seals in the rear end. I need to know how to determine what shim to put on the rear pinion. According to my shop manual you take the number on the pinion gear and the number on the case and do some math. Problem is there are no numbers on the pinion gear. I measured the old one and it reads .18. According to the parts list the smallest they list is .3. Anyone got any information I would appreciate it. Also if anyone knows of or has a pinion for a 1998 or newer Wolverine that is in good shape and they want to get rid of it let me know what you want.

Thanks

I had my caliper readings in inches not mm. Once I switched it over the old shim measures about .050.
