MAINTENANCE
Drive Shafts
Type of Grease - A good quality NLGI #2 EP
grease, lithium soap base should be used to
grease the needle bearings in cross journals,
shield bearings, telescoping members and CV
centering mechanism. For heavy duty applications
a compatible grease with 3 to 5% molybdenum
disulfide additive may be used.
Cross Journals - Every 8 hours. Lubricate until
grease purges from underneath all four needle
bearing caps. To access the cross journals on
center drive shafts, remove the shield retaining pin
and pivot the shield out of the way.
Shield Retaining Bearings - Every 8 hours. The
shield bearings are greased by a fitting molded
into the shielding bell. Three pumps are required.
Check that the drive line shielding is not damaged
and rotates freely on the driveline.
Telescoping Tubes - Every 8 hours. Apply grease
to the collar located at the middle of the shaft. The
grease fitting on this collar will come exposed
when the snow blower is down on the ground.
Occasionally (monthly) pull the drive shaft halves
apart and apply grease to all sides of the slip shaft.
At least once per year the shielding should be
removed and the old grease removed with a
solvent. A fresh coat of grease should then be
applied to the entire surface of the inner tube.
IMPORTANT - If the universal joint sliding
members are allowed to dry out to the point where
two halves cannot slip freely, damage to the rotary
cutter or tractor may occur.
Always wear protective gloves when handling grease.
