2. Place an oil pan under the differential gear
case to collect the used oil.
3. Remove the differential gear oil filler bolt, the differential gear oil drain bolt and their gasket
to drain the oil from the differential gear case. 4. Install the drain bolt and its new gasket, and
then tighten the bolt to the specified torque.
5. Refill with the specified amount of the recom- mended differential gear oil. NOTICE: Be
sure no foreign material enters the differ-
ential gear case.
[ECB00412]
TIP Do not exceed the specified differential gear oil
quantity when filling. Overfilling will cause the oil
to seep out of the breather hose during and af-
ter riding.
 The differential gear case capacity is greater
than the recommended oil quantity, therefore
the oil level cannot be accurately checked from
the oil filler hole. 6. Check the oil filler bolt gasket for damage,
and replace it if necessary.
7. Install the oil filler bolt and its gasket, and then tighten the bolt to the specified torque.
Recommended differential gear oil:
Yamaha Friction Modified Plus Shaft Drive Oil (Part No.: ACC-SHAFT-PL-32) or SAE 80
API GL-4 Hypoid gear oil
Oil quantity: 0.23 L (0.24 US qt, 0.20 Imp.qt)
