Note: Inspection of shaft pos. 9 in course of maintenance 1
During the course of maintenance 1, the shaft pos. 9 should be checked for wear. With
premature wear, caused by correspondingly harsh operating conditions, it is recomended to
run the maintenance 2.
The wear on the shaft pos. 9 can be visible at two places.
Worm:
The wear on the tooth flanks is visible at the worm. In this case, sharp edges on the tooth
flanks can be clearly observed.

Bearing position to bushing pos. 8:
If the position on the shaft which serves as a counter surface to the bushing pos. 8 is worn,
in most cases this indicates particles in the system. Solids deposited in the bushing cause
prenature wear of the shaft.
Note: If the shaft is worn at this position, the bushing pos. 8 should be replaced.
