Boom / Lift Cylinder Assembly for Komatsu PC120-6, PC128, PC130, PC138, PC138US-8 Excavator
This boom cylinder assembly is a ready-to-fit replacement for the Komatsu PC120-6, PC128, PC130, PC138, PC138US-8, getting the boom lifting strongly and holding steady again. It arrives fully assembled with barrel, rod, piston, gland and seals, manufactured to OEM dimensions so it bolts straight in.
If the boom sags overnight, struggles to lift a full bucket, or the rod shows scoring and leaks, a complete replacement cylinder is the reliable fix. Replacing the whole cylinder means no chasing parts, no machining delays and no guesswork about what else is worn inside. Mid-size excavators like this are the backbone of many civil fleets, often working long shifts on drainage, roadworks and earthmoving contracts.
