3. Synthetic lubricants are also recommended, especially under severe service. These
lubricants are more viscosity/temperature stable and provide service over a broad
range of temperatures. These lubricants have a longer service life, require fewer oil
changes and increase the life of the gearbox by reducing friction and wear. This
lubricant is also compatible with nitrile seal material and alloy bronze gear material.

4. The oil in the reducer must be maintained at the proper level. The reducer must be at
rest when the oil level is checked.
5. In a new unit, the oil should be changed (or filtered) after four weeks (or 100 hours) of
use. The case should be flushed with light oil to remove any foreign substances.
6. After the initial oil change, the oil should be changed once every 6 months or 2500
hours, whichever occurs first.
7. More frequent oil changes may be necessary when there are severe duty or dirty
conditions present.
8. Special order speed reducers supplied with ComDRIVE® actuators may or may not
be factory lubricated. In this case, a separate O&M can be provided for the special
reducer.

2-3 Disassembly of ComDRIVE® Jacks
Remove the (4) bolts and washers (item #19 and 18) from the adapter/reducer f-flange
(item #17). The reducer and motor can now be removed from the jack. The motor included
with the ComDRIVE® is not user serviceable, however, it can be replaced. Replacement
parts for the gear reducer can be obtained from Joyce/Dayton by contacting
[email protected] .
Use the appropriate disassembly procedure for the ComDRIVE® jack– if the lifting nut is
outside the jack on the screw, it is a Keyed for Traveling Nut (KFTN) jack, (also called a
“rotating screw” jack), otherwise the jack is a translating model or a keyed model. Handle
machined parts with care, and maintain an “order of disassembly” to aid in re-assembly.
Remove all couplings, screw support bearings, etc. before beginning disassembly.
