Acceptable lubricants
Replacement Oil must be the same as, or equivalent to the above.
Grease quality requirements
N/A
– Greased for Life is utilized for grease lubricated bearings
Lubricate the bearings with oil (216.40 pumps only)
WARNING:
Risk of explosive hazard and premature failure from sparks and heat generation. Ensure
That the bearings are properly lubricated prior to startup.
Remove the filler plug in the top of each housing. Refer to the GA or outline drawing for
location.
Fill each housing using a funnel.
Reinstall the filler plug and tighten.
Check that the oil level is correct. The correct oil level is at the center of the sight glass, when
the pump is stopped. During operation the sight glass gives a false oil level reading.
Lubricate the gear/bearings after a shutdown period (216.40 pumps only)
1. Fill each housing with the proper lubricating oil after cleaning.
