Maintenance

Your BRAVO

®

reducer has been tested and adjusted at the factory. Dismantling or replacement of components must be done by Factory to maintain

the warranty .

Mounting bolts should be routinely checked to ensure that the unit is firmly anchored for proper operation .

Seals: The BRAVO

®

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 below .

1 . Remove the worn seal without damaging the shaft surface or the seal bore. This can be done by drilling a .062” diameter hole in the seal

casing (being careful not to drill into the bearing behind the seal). Screw a #10 sheet metal screw into the hole and pry out the seal.

2 . Clean the seal bore of sealant .

3 . Before installing the new seal, use electrical tape to cover any keyways on the shaft to prevent seal lip damage .

4 . Grease the seal lips with bearing grease and apply a sealant to the seal bore .

5 . Slide the seal onto the shaft being careful not to fold the inner lip over on any shaft steps .

6 . Press the seal into its bore with a sleeve that presses on the seal casing, being careful to keep the seal square in its bore .

If seal leakage has resulted in the loss of a significant amount of lubricant, it may be necessary to add more . Contact Factory for more detail .

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.
