GEARBOX MAINTENANCE AND REPAIR.
5.1.
Gearbox contains 12 fl/oz. of
85w-140
gear lube.
NOTE:
In normal service it should not be neces-
sary to change the gear lube on a regular basis.
The gear lube can be drained and replaced if the
transmission is to be opened for repair, or if the
fluid becomes contaminated, for example by
pressure washing.
NOTE:
Damage caused by water in the trans-
mission is NOT warrantable.
5.2.
To check the fluid level clean the surface sur-
rounding the fill plug. See Figure 5.2.
5.3.
Remove the fill plug with a 7/16” open end
wrench. See Figure 5.3.
NOTE:
A bent piece of wire can be used as an
improvised dipstick.

tine shaft. Remove all dirt, rust, and scale using
emery cloth or a wire wheel.
