On 04/22/03 Mark Johnson wrote the following regarding lubricating the
Yamaha FJR1300's shaft drive splines. Former BMW owners know how important this
maintenance procedure can be...
At 6k miles I did the first tire swap today. While in there I checked the
splines to be sure. This is what the Yamaha assembly drones consider
sufficient for the job. After initially writing about this, some other
Feejer owners have e-mailed me and told me their's was just as "dry". It's
not a good thing, folks. Check your splines each time you do a tire swap.
It's quick and easy and can save you a load of heartache over the life
of the bike.
- Get a factory service manual.
It's cheap insurance over the life of the bike.
- Remove rear wheel (including brake caliper from rotor, etc.)
- Remove the 4 acorn nuts to the front of the rear drive "pumpkin" where
it bolts to the swing arm.
- Carefully pull the assembly straight backward. The shaft will come with
- Clean and re-lube the front spline. I found that Mobile Super Syn grease
was the exact same color and consistancy as that already on the spline.
With BMW and others re-labeling Mobile synth products, my bet this is the
same story with Yamaha's rear pumpkin "magic juice" they sell for $38 a
pint. Clean/lube the rear hub splines while the tire is out too.
- Reassemble in reverse order, being carelful to line up the splines so
they slip right in without being forced. Be sure to also clean and grease
the splines on the rear drive where they mate to the rear wheel.
- Torque the 4 acorn nuts on the rear hub to 42 Nm (30 ft-lbs).
- Go ahead and swap out rear drive ("pumpkin") lube while you're in there.
You don't have to with the above expesnive Yamaha gear oil, but why not?
It's fast and easy.
