Bucket Hydraulic Cylinder to Suit Komatsu PC18MR Mini Excavator

This bucket (crowd) cylinder assembly brings strong, controlled bucket curl back to your Komatsu PC18MR. It arrives fully assembled with barrel, rod, piston, gland and seals, manufactured to OEM dimensions so it bolts straight in.

Because the bucket ram sits closest to the work, it is the cylinder most often damaged — a bent or pitted rod will keep tearing seals until the whole unit is replaced. Replacing the whole cylinder means no chasing parts, no machining delays and no guesswork about what else is worn inside. On a compact machine like this every cylinder works hard — footings, drainage runs, pool digs and backyard landscaping all lean on smooth, precise hydraulics.
