Gear Box
The gear box is fi lled with oil at the factory and does not require
service. If a visible leak appears at one of the seals, repair the
box and fi ll half-full with 85W90 oil.
The drive line components are protected by a shear pin located
on the gearbox coupler. If the pin fails, determine the reason for
the failure, remove, and install a new shear pin.
To replace the shear pin:
1. Loosen the bolt on the locking tab and rotate the tab out of
the machined groove in the shear pin.
2. Remove any broken shear pin pieces and line up the holes in
the coupler with the hole in the shaft.
3. Install a new shear pin.
4. Rotate the lock tab into the machined groove on the shear pin
and tighten the bolt on the tab.
