Gearcase Disassembly
IMPORTANT: Due to the manufacturing process, the
pinion and ring gear assembly are NOT intended to be
disassembled and replaced.
Pinion and ring gear shimming information is NOT
pr
ovided. The components are matched at the factory
which requires special OEM tooling in order to
properly assemble and shim the gears.
In the event damage to the gears or housing requires
re
placement, the entire assembly must be replaced.
1. Drain and properly dispose of used gearcase fluid.
2. Remove remaining cover screws from rear gearcase.
3. Remove the ring gear/axle spool assembly. The
bearings
are a slip-fit and will slide off the axel spool.
NOTE: Record the thickness of the shim pack
loc
ated under each bearing. Keep the shims
together for reassembly.
4. Inspect each axle spool bearing and race for signs of
we
ar or damage. Replace races if required using
standard bearing puller tools.
