LUBRICATION
Seal Assembly
(Figure 3)
Fill the grease cup (13) through the grease fitting
with No. 2 lithium base grease until grease es-
capes from the relief hole. Turn the grease cup arm
counterclockwise until it is at the top of the stem;
this will release the spring to apply grease to the
seal (see Figure 6).
Before putting the pump into service, bleed off the
seal cavity and supply line to eliminate any air
pockets in the seal area.
Engine
Consult the literature supplied with the engine, or
contact your local engine representative.
