GREASE PIN CRANK BEARING (Figure 6)
1. Remove fan duct (2) (Key #5)
2. Remove the nuts and bolts and then the fixed scroll from
the air end.
3. Grease all three pin crank bearings as indicated on the
grease delivery chart above.
Use only Powerex genuine
grease. Pump grease gun before
feeding to eliminate air from grease passage of the needle
adaptor.
NOTE:
Each pump of the grease gun equals 0.65g of grease.
The volume of grease is less after the 2nd pump since some
of the grease supply will remain in the grease passage.
MAINTENANCE INDICATORS
The PUMP MAINT indicator will activate when the running
hours of
any
pump accumulates to a required maintenance
interval. The system is designed for multiple pumps to accu-
mulate hours evenly and for maintenance intervals to be ap-
proached simultaneously. To prevent nuisance PUMP
MAINT indications, all applicable maintenance counters
should be reset after the required maintenance actions are
performed.
