INTRODUCTION
The following instructions apply to RAIDER
®
Worm Gear Speed Reducers. When ordering parts or requesting information
be sure to provide all the data stamped on the reducer nameplate.
EQUIPMENT REQUIRED
In addition to standard Mechanic's tools, the following equipment is required: arbor press, wheel puller, torque wrench,
dial indicator, seal driver, bluing, adhesive sealant, snap ring pliers for internal and external rings.
GENERAL INSTRUCTIONS
Housings - Clean external surfaces of reducer before removing seal cages and end covers to
prevent dirt from falling into the unit. Record mounting dimensions of accessories for reference
when reassembling. If it is necessary to remove the reducer from its operating area, disconnect
all connected equipment and lift reducer from its foundation.
Seals - Replacement of all seals is recommended when a unit is disassembled. However, if seals
are not to be replaced, protect seal lips by wrapping shaft with plastic tape coated with oil or
grease before removing or replacing seal cage assembly. Clean the shaft but do not use any
abrasive material on the shaft surface polished by the seal.
If the reducer is painted, extreme care should be taken to mask the shaft
extensions and rubber surface of the seals. Paint on the shaft adjacent to the
seal or on the seal lip will cause oil leakage.
