Gear backlash should be checked at
installation and again at regular intervals
to prevent injury or damage that might be
caused by gear tooth failure. This should be
done by measuring the rotary movement
of the output shaft (rotating alternately CW
and CCW) at a suitable radius while holding
the input shaft stationary. Gears should be
replaced when the backlash equals four
times the measurement taken at installation.
Relubrication:
Service life and efficiency of gears and
bearings will be affected by oxidation
and/or contamination of the oil used.
Longer life will be obtained by periodic
relubrication in accordance with the following
recommendations.
• After an initial operating period of
approximately 250 hours, the housing
should be drained, preferably while warm.
• Refill to the proper oil level with fresh oil.
• Under normal conditions, the drive should
be relubricated at intervals of 2500 hours
of operation or six months, whichever
occurs first.
• Synthetic lubricants will allow extended
lubrication intervals due to its increased
resistance to thermal and oxidation
degradation. It is suggested that
the initial oil change be made at 1500
hours and, thereafter, at 5000 hour
intervals.
