AR adapter maintenance
The following table lists the obligatory intervals and the corresponding measures:
Time interval
What to do?
•
Every 3000 hours of
operation, at least every 6
months
•
Check the running noises to detect possible
bearing damage.
•
Visually check the adapter for leakage.
•
After 25000 – 30000 hours
of operation
•
Change the bearing grease.
•
Change the oil seal. Do not mount it in the same
track.

Maintenance of AR adapter with slip clutch
If you use an adapter with slip clutch, the wear parts are affected by many factors.
This is why the inspection intervals are short.
The following table lists the obligatory intervals and the corresponding measures:
Time interval
What to do?
Chapter
At least every
3000 operating
hours
•
Inspect the friction lining and
the cup springs. If necessary,
replace them.
•
If the slip torque is too low, ad-
just it accordingly.
Chapter "Inspecting/repla-
cing the friction lining, adjust-
ing the slip
torque" (→
6.6.1
Inspecting the friction lining
If the friction lining thickness is reduced by more than 50% compared to the original
state, replace the friction lining (see chapter
Replacing the friction lining and adjusting
114)).
The following table lists the friction lining thickness in original state:
