Seal Replacement - Western 1200 Operator's Manual & Parts Breakdown

SEAL REPLACEMENT

It is recommended to replace the bearings anytime these seals are replaced, as they are relatively inexpensive
versus the cost of downtime and labor� The paddle shaft should be thoroughly inspected for grooves� Paddle
shafts with a groove 1/8" or deeper should be replaced�
Disconnect the gearbox from the shaft coupler and remove the engine and gearbox from the engine
compartment� Remove the bolts holding the drum's pillow block bearings to the frame and remove the
drum from the frame� Remove the paddles from the paddle shaft if the shaft is to be replaced� Remove the
pillow black bearings from the shaft� Removing the ange mount bearing exposes the seal and grease ring
assemblies� For seal installation, put a small amount of grease on the rubber seals so they will slip on the
shaft� The seals are purposely undersized to allow wear� Assemble as indicated on the illustration� Completely
ll the seal cavity with waterproof grease�
