Description of Change: A constant torque hose clamp is available for the above listed machines. Due to the extreme temperature changes, a hose will heat set which causes the hose clamps to loosen resulting in leaks. The new, constant torque hose clamp can be used in place of any standard hose clamp.
Adaptable To: The new 8T-4983 Hose Clamp directly replaces the former 9M-2904 Hose Clamp. The changes to the 8W-6235 Transmission Oil Lines Group and the 8W-6215 Transmission Oil Lines Group are adaptable back to earlier machines.
