Note: Inspection of the worm gear during maintenance 1
During maintenance 1, the worm gear should be checked for wear. This can be done by a
visual inspection. In case of premature wear, caused by harsh operating conditions, the shaft
pos. 9 should also be inspected.
The following further steps are necessary for this:
Impeller Page 68
Gear frame Page 69 – 70
Shaft pos. 9 Page 70 – 71
If the shaft pos. 9 also shows heavy wear, it is recommended to perform maintenance 2.
