Small Gear Reducer Operation and Maintenace
BEFORE PLACING THE DRYER IN OPERATION, Remove small screw from vent tube in top
rear of each Gear Reducer case. Remove the cork from the oil level inspection cup. If the oil
level is correct, the oil level inspection cup will be half filled with oil. If not, add oil. Oil may
be added to the Gear Reducer by removing the filler plug in the top rear of the Gear Reducer
case. Do not operate a Gear Reducer unless the drain plug is tight, and the vent tube screw
removed.
If it is necessary to return a Gear Reducer to the factory, either replace the small screw in the
vent tube and plug the oil-level inspection cup with a cork, or drain all oil from the reducer by
removing the drain plug located in the bottom rear of the Gear Reducer case.
EACH GEAR REDUCER is filled with 5 pints of Cissell TU3465 transmission oil before leav-
ing the factory. Change oil once every 6 months.
THE LARGE TIMKEN BEARINGS, which support the worm gear and basket load, must
operate in a preloaded condition, that is the worm gear must not have end play. The Gear
Reducer is assembled at the factory to provide a 16-20 inch lb. pre-load on these bearings.
THE SMALL TIMKEN BEARINGS, which carry the worm must operate in a pre-loaded
condition, that is, the worm must not have end play. The Gear Reducer is assembled at the
factory to provide a 2-4 inch lb. pre-load on these bearings.
