XCMG Clutch Booster Cylinder 130301479
When a crane driver reports a heavy pedal or incomplete clutch release, the booster is often blamed first. Part 130301479 should be matched only after checking the full clutch-assist circuit.
What buyers usually want to confirm: Will it bolt on, will the ports face the correct way, and will the pushrod give the correct free play?
Fitment Evidence That Saves Time
XCMG part number 130301479

Port threads and orientation
Pushrod length and clevis

When This Part Becomes Relevant
This XCMG clutch booster cylinder becomes relevant after confirmed internal leakage, sticking or loss of assist. Master-cylinder wear, low air pressure, linkage or clutch damage can feel similar.
A Practical Workshop View
Depressurize, cap lines and preserve the old pushrod setting. Bleed the circuit, adjust free play to service data and road-test engagement without clutch slip.
