out of the bottom of the oil level port. Allow several
minutes for oil to settle, then recheck oil level. Add oil if
necessary.
NOTE
: Oil should be checked or added when reducer is at
ambient temperature.
CAUTION
: Underfilling reducer may cause product
damage. Overfilling reducer may cause excessive oil
temperatures.

may exist . Once threads are free to hand rotate, place a
heavy cloth over the plug and rotate counterclockwise until
removed.
3. With the proper size oil drain pan (reference oil quantity
on nameplate) in place, remove the drain plug.
CAUTION
: Oil may be hot. Do not drain until oil is at
ambient or a safe temperature.
4. After oil is removed, replace oil drain plug, sealing it in
the process using thread sealant.

grease for the application. Attach grease gun to grease
insert and pump grease into seal carrier.
3. Stop greasing when a sufficient amount of grease
purges out of seal carrier next to shaft.
