Filter And Reservoir

Filter assembly (2, Figure 42-8) is mounted on right
upright (1) and filters the grease when the grease
supply is refilled through the quick fill fittings.
Grease is pumped into the filter through filter inlet
hose (4) routed from the service center and then
flows out the filter through hose (3) to grease reser-
voir (5). Vent hose (7) purges air from the reservoir
as it is being filled and prevents a vacuum as grease
is pumped out.
Cap (6) allows the reservoir to be drained, if desired,
and a plate secured on the end of the reservoir
(frame torque tube) can be removed if the reservoir
requires cleaning.
