Clutch Greasing Guidelines

To ensure long life and proper operation of the Release Mechanism of the clutch, it is important to properly lubricate the following areas.

Lubrication

  • Release Bearing: The cast iron bearing housing will be equipped with either a standard grease fitting or a lubrication tube extension. If a lubrication tube is not present, it is necessary to remove the inspection cover to gain access to the grease fitting. Apply grease until it purges from the rear of the housing. Grease on the Transmission Input Shaft will extend the life of the bronze bushings inside the release sleeve._Graphics/Web/TRSM_0970_Purging Procedure.png
  • Release Bearing Wear Pads: Where the Release Fork contacts the bearing housing, there are small hardened steel pads. Apply a small amount of grease to the wear pads where the Clutch Release Fork contacts.
  • Low Capacity Inertia Brake (LCIB): The LCIB does not require lubrication for proper functionality.
  • Cross Shaft Bushings: Lubricate both the left and the right Cross-Shaft Bushings per OEM recommendations.
  • Clutch Control Linkage: Lubricate the clutch linkage bell cranks and pivot pins per OEM recommendations.
  • Pilot Bearing: The pilot bearing inside the flywheel is a sealed for life bearing and requires no lubrication. Use a premium pilot bearing to prevent clutch drag and early bearing failures (C-3, C-4, C-5 Suffix).

Recommended Lubrication

Caution
Incorrect grease and improper lube procedures will cause bearing failures, bushing wear-out, and yoke tip and bearing wear pad wear.
Notice
Eaton recommends the use of Roadranger EP2 for release bearing lubrication, or an equivalent Lithium Complex, NLGI #2 or #3 grease with an NLGI LB/GC performance rating and a dropping Point temperature of 220 °C (428 °F) or higher. Failure to use the proper grease may affect bearing life and void the warranty coverage on your Eaton product.

Lubrication Interval

For recommended lubrication intervals, see Manual TCMT0021, Roadranger Lubricant Products, or call 1-800-826-HELP (4357).
