The PC2000 Front Shovel Arm Cylinder is a premium aftermarket hydraulic component engineered for the Komatsu PC2000-8 Loading Shovel. Designed to replace OEM Part Number 707-E1-01850, this cylinder is built to withstand the immense breakout forces and high-cycle impact loads typical of open-pit mining operations.
As the primary force-generating component for the shovel’s crowding action, our Arm Cylinder features an enhanced rod structure and heavy-duty guide bushings to prevent side-load damage and extend service intervals in harsh mining environments.

FAQ
Q1: What is the ‘crowd force’ specification for 707-E1-01850?
A: Peak crowd force (the force the arm cylinder delivers to drive the bucket into the ore face) is 1,650 kN at rated working pressure. This matches the Komatsu OEM specification exactly.
Q2: How often does 707-E1-01850 need seal service?
A: In continuous shovel operation on hard ore, plan seal service every 4,000-6,000 operating hours. With HVOF coated rod and low-temp seal package, seal life extends to 6,000-8,000 hours.
Q3: Is your 707-E1-01850 Komatsu-genuine-compatible?
A: Yes. Our cylinder is built to Komatsu OEM drawing specifications and uses the same mounting dimensions, port locations, and thread standards. It is a drop-in replacement.
