What to do?
•
Every 3000 operating
hours, at least every 6
months
•
Check the running noises to detect possible
bearing damage.
•
Visually check the adapter for leakage.
•
After 10000 operating
hours
•
Check the rotational clearance.
•
Visual check the cam ring (AM) or coupling ring
(AQ., AL).
•
After 10 000 operating
hours with NBR/FKM oil
seals
•
After 20 000 operating
hours with Premium Sine
Seal (PSS) adapter oil
seals:
