6.4.1.2 Grease quantities for roller bearings
during assembly
The hollow areas between the cylinder bodies are filled in the
factory 30% - 50% with grease. This grease filling is sufficient
for operation of the bearing under conditions normally en-
countered.
6.4.2 Bearing replacement
To ensure problem-free operation of the pump, replace the
bearing after about 15,000 to 20,000 hours of operation.
6.4.2.1 Premature bearing replacement
If persistent external conditions such as dust, splashed water,
aggressive ambient air, or high temperatures promote wear,
bearings should be replaced after about 5000 hours of oper-
ation.
