Recommended Lubricants for
Enclosed Gear Reducers
The gear reducer requires 7.8 oz (230.7 ml) of clean
lubricant as listed above.
The lubricant must remain free from oxidation and con-
tamination by water or debris, since only a very thin film
of oil stands between efficient operation and failure. To
assure long service life, the reducer should be periodi-
cally drained (preferably while warm) and refilled to the
proper level with a recommended gear oil. Under normal
environmental conditions oil changes are suggested
after the initial 250 hours of operation and thereafter at
regular intervals of 2500 hours or every 6 months.
Synthetic lubricants allow extended lubrication intervals
because of increased resistance to thermal and oxida-
tion degradation. It is suggested that the initial oil
change be made at 1,500 hours, with additional oil
changes scheduled at 5,000 hour intervals.
