SH-1264 Clutch Booster for XCMG Cranes
The SH-1264 clutch booster assists clutch actuation on compatible XCMG crane carriers. Correct pneumatic or hydraulic port arrangement, pushrod geometry and mounting interface are necessary for full clutch release and controlled pedal return.
Identification and Matching
Model SH-1264 on the original label
Carrier model and machine serial number
Port size, position and line connection
Pushrod length, clevis and adjustment range
Mounting studs, flange and overall orientation
Application and Service Scenarios
The booster may be replaced after confirmed internal leakage, loss of assist, sticking operation or damaged housing. A heavy pedal, incomplete disengagement or poor return can also originate from low air pressure, master cylinder faults, linkage wear, clutch components or incorrect adjustment.
Inspection and Installation
Depressurize the system, cap open lines and compare pushrod settings before installation. Bleed or charge the circuit per service instructions, adjust free play correctly and check for leaks. Test clutch release and engagement at low speed before road operation.
Frequently Asked Questions
Does a heavy pedal always mean the booster failed?

Use the specified measurement and free-play procedure.
What must match besides SH-1264?
Ports, mounting, pushrod and carrier configuration must match.
Export Packing
