Tube Ref No.
Extreme Grease
2-4-C with PTFE

• Driveshaft bearing
IMPORTANT: It is important not to use a general all‑purpose grease for this bearing. The lubricant recommended is a
water‑resistant grease of the proper consistency for this application. If a substitute is used, be sure that it is
water‑resistant and of the same consistency.
i. Pull the vent hose off of the grease fitting.
ii. Pump in grease through the grease fitting, using the grease gun provided, until excess grease starts to exit the
vent hose.
iii. Reconnect the vent hose onto the grease fitting after greasing.

NOTE: After 30 hours of operation, pump in extra grease to purge out any moisture. Visually inspecting the purged
grease at this time will give an indication of conditions inside the bearing housing. A gradual increase in moisture
content, indicates seal wear. If the grease begins to turn dark or dirty gray, the driveshaft bearing and seals should be
inspected and replaced if necessary. Some discoloration of the grease is normal during the break‑in period on a new
set of seals.
