Maintenance
Your
IRONMAN BY OHIO GEAR™
reducer has been tested and adjusted at the factory. Dismantling or replacement of components must be
done by LEESON to maintain the warranty.
Inspect the stem of the Enviro-Seal often to ensure it is clean and operating properly.
Mounting bolts should be routinely checked to ensure that the unit is firmly anchored for proper operation.
Seals: The
IRONMAN BY OHIO GEAR™
line of speed reducers utilize premium quality seals which are state-of-the-art in sealing technology.
Seals are, however, a wear item and eventually need to be replaced. Replacement can easily be accomplished by following the procedure on page
5.
If seal leakage has resulted in the loss of a significant amount of oil, it may be necessary to add more lubricant. For normal ambient temperature
conditions, LEESON recommends Mobil SHC 634 synthetic gear oil for worm drives, and Mobil SHC 150 for helical drives.
CAUTION
Always check for proper oil level after filling. Do not overfill or underfill with oil, or injury to personnel, reducer, or
other equipment may result.
Do not mix different oils in the reducer.
