GREASING THE REAR DRIVE BEARING AND
EXTENSION COUPLER SHAFT
Locate the grease zerks for the rear flail drive extension shaft. Make sure the
zerks are clean before injecting grease. One pump of grease into flange zerk and
shaft coupler once every day or for every 8 hours of service.
GREASING PUMP DRIVE SHAFT COUPLER
With engine stopped, ensure drive shaft alignment by grasping coupler and sliding
back and forth. Coupler should slide freely with approximately 1/8" of end play. If
coupler does not slide freely, inspect for loose pump mount bolts, or damaged or
loose crank shaft adapter. Inject Lithium-Complex Extreme Pressure grease
conforming to NLGI2-ISO 320 specifications into coupler until grease begins to
protrude from ends. Grease daily or every 8 hours. Do not over grease.
