Komatsu — Filter Assembly Element

OM4206 06/06 Maintenance - Section 42 Automatic Lubrication System Page 42-9 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. Filter Assembly Element Filter assembly element (5, Figure 42-9) must be replaced if bypass indicator (2) shows excessive ele- ment restriction. 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. FIGURE 42-9.
