Lubrication Information

To ensure proper lubrication and operating temperatures in these units, it is most important that the proper
lubricants be used and that correct oil levels be maintained.
Recommended Lubricants
The following lubricants are recommended, in order of preference, for use in all Chelsea Split Shafts and Gear
Boxes.
Models 700, 712, 721, 732, 741, 931, 2230
Temperature
Above 0°F
Below 0°F

Do Not Use Extreme Pressure Additives, such as found in multi-purpose or rear axle type lubricants. These
additives are not required in our split shafts and gear boxes, and they may in some cases create transmission
problems. Multi-purpose oils, as a group, have relatively poor oxidation stability, a high rate of sludge formation
and a greater tendency to react on or corrode the steel and bronze parts.
Oil Changes
We recommend an initial oil change and flush after the split shaft is placed in actual service. This change should
be made any time following 1,000 miles, but never to exceed 4,000 miles, of over-the-road service. In off-highway
use, the change should be made after 24 and before 100 hours of service have elapsed. There are many factors
that influence the following oil change periods, and we have not specified a definite mileage interval.
In general, it is suggested that a drain and flush period be scheduled every 20,000 miles for normal over-the-
highway operations. Off-the-highway usually requires an oil change every 30 days. The oil level in the split
shaft should be checked every 2,000 miles on-highway, or every 24 hours in off-highway operation. When it is
necessary to add oil, we recommend that types or brands of oil not be mixed. The correct oil level in all Chelsea
Split Shafts is established by the filler plug opening.
Refill—First, remove all dirt around the filler plug. Then refill with new oil of a grade recommended for the existing
season and prevailing service.
Overfilling
Do not overfill the gear box or split shaft. Overfilling usually results in oil breakdown due to excessive heat and
aeration from the churning action of the gears. Early breakdown of the oil will result in heavy varnish and sludge
deposits that plug up oil ports and buildup on splines and bearings. Overflow of oil usually escapes onto clutch or
parking brakes, causing additional trouble.
