I have made a set of tools for servicing the FJR rear drive unit. These perform the same function as Yamaha p/n's 90890-01229 / YM-01229 (pinion bearing retainer wrench) and 90890-04050 / YM-04050 (gear holding tool). They allow you to remove the coupling and bearing retainer. Although the disassembly and repair process may be covered in the shop manual, there is a similar (Venture) write up with pictures here: https://www.venturers.org/Tech_Library/inde...1006&id=383. These will also work on many other Yamaha shaft drives.
I'm going to send a set of these adrift in the fjrforum community. This or another thread in an approriate category could be stickied to facilitate the requests and keep track of their whereabouts. Once I send them off, you're/they're on your/their own. That being said, the following are only suggestions:
-This is strictly pay it forward-you use them, you pay shipping to the next user. Unfortunately, the socket is too large to fit in the cheapest fixed rate Priority Mail box. I believe the medium is currently $10.XX.
-Please make sure you indeed need the tools before requesting them. Leakage from the swingarm weep hole could simply be a faulty driveshaft-coupler seal which requires no special tools to remedy. Further disassembly is required only when replacing the seal, o-ring and bearing associated with the pinion gear.
-Once recieved, try to complete your project in a timely manner so they are available for the next user.
Note: I made these from dimensions I took from my gen 1 while replacing the driveshaft seal and haven't actually checked the fit. I'm 99% sure they will work. If there is a problem please let me know.
