2.5 Frame
NLGI #2 EP molybdenum disulfide fortified grease is preferred for all sliding contact type applications such as
frame pins.
Frame pivot points: Daily during the first week of usage, and every 50 hours of operation thereafter, 16 locations:
(1) Hitch clevis, swivel
(1) Hitch frame, main pivot
(2) Steady bearing stand
(1) Arm link
(1) Gearbox mounting stand, main pivot
(1) Gearbox mounting stand, link
(1) Arm link
(2) Castor frame link – FLX15 only
(1) Arm, main pivot
(1) Castor frame, pivot – FLX15 only
(1) Hydraulic cylinder – rod end
(2) Castor pivot sleeve
(2) Hitch tongue – cross pin grease zerk is on bottom side of sleeve
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.
CAUTION!
2.4 Universal Joint Assemblies:
-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
centeringmechanism. 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.
-Shield Retaining Bearings: Every 8 hours.
The shield bearings are greased by a fitting molded into the shielding bell. Three pumps are
required.
IMPORTANT: Check that the driveline shielding is not damaged and rotates freely on the driveline.
-Constant Velocity Body: Every 4 hours.
The housing for the CV body serves as a reservoir for the lubrication of the centering mechanism.
Approximately 30 pumps are required every 4 hours.
-Telescoping Tubes: Every 4 hours. Apply grease to the collar located at the middle of the shaft.
The grease fitting on this collar will come exposed when the cutter wings are laying flat.
Occasionally (monthly) pull the universal joint halves apart and apply grease to all sides of the slip
shaft. At least once per year (more often in dusty or dirty conditions) 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.
