10 | Maintenance
• Inspect drive belt and pulleys periodically for excessive wear.
• Check cables for wear. Ensure they are clear of potential damage from
moving parts.
• Periodically inspect the Speed Reducer, located in the gearbox, for any
signs of impending service. The following items may indicate need for
service:
• Oil leaking from seals—indicates that shaft and/or seals
are worn and need replacing. Keep dirt and foreign
particles off shafts in the area of the seals to minimize
wear.
• Oil leaking from input or output caps, cap screws or
pipe plugs—might be corrected by tightening or
removing and recoating a pipe sealant as required
before tightening. If this does not correct the leaking
condition, disassembly will be necessary to replace o-
rings.
• Excessive end play of shafts—if there is noticeable
shaft movement when couplings are removed and shaft
is moved back and forth, it may be an indication of
bearing wear. Replacement may be required.
• Excessive backlash—would indicate worn gears, which
may need to be replaced. Excessive backlash is gear
play of more than ± 2 degrees.
Screw threads and the threaded hole must be degreased before
application of LOCTITE®.
