Reference: Service Magazine Article; January 14, 1991; Page 11. "New Load Piston Body Resists Wear Of Transmission Pressure Control Valves Due To Side Loading".
Description of Change: The 6T-5659 Load Piston Body has been replaced with 6Y-7216 Load Piston Body in all Off-Highway Trucks and Wheel Tractor Scrapers equipped with Individual Clutch Modulation (ICM) controls. 6Y-7216 Load Piston Body directs oil pressure to the top of the load piston body which will decrease possible pressure side thrusts and help control clutch modulation operations.
NOTE: Former 6T-5659 Load Piston Body has NOT been canceled and may be used in other Caterpillar equipment.
Adaptable To: Effective on Off-Highway Trucks and Wheel Tractor Scrapers equipped with Individual Clutch Modulation (ICM) controls. Adaptable to all earlier models.
