Debris in Bearings
1. Stop running
2. Flush bearing through with grease
– pumping at 20 strokes/min for 5
minutes. Stop pumping
3. Try running to see if problem is
resolved. If not try flushing again
Pressure Locked
1. Check grease pressure. If it is
greater than well pressure but
falling then allow to equalise then
continue running without pumping
grease for the rest of the
operation.
2. If grease pressure is constant and
higher than well pressure then
bleed grease pressure on the
other side of the check valve [note
a safety case will be required for
this]
3. Continue running without injecting
grease
