Right-circuit pressure low or PC200-8 boom speed falling behind arm speed? A worn PC200-8 right cylinder block and valve plate allows right-section bypass to grow, breaking the flow balance between front and rear pump sections. RITO supplies this matched right barrel-and-valve-plate set to restore PC200-8 right-pump displacement from the first operating hour.

In StockPC200-8 Cylinder Block with Valve Plate (Right) for Kawasaki K3V112DT piston pumps on PC200LC-8, PC210-8 and PC220-8 excavators. The K3V112DT tandem pump's right section governs boom and combined-load circuits. Barrel and valve plate are matched by RITO to a common lapped surface so the sealing interface achieves correct clearance without a break-in leakage period.

Barrel face and valve plate sealing surface lapped as a matched pair to Ra 0.1 finish, eliminating break-in leakage and restoring right-pump efficiency immediately.
Port geometry matched to the right section of the K3V112DT tandem pump to prevent cross-port leakage between left and right circuits under combined-function loading.
One assembly covers PC200LC-8, PC210-8 and PC220-8 right pump positions, simplifying spare parts procurement for PC200-8 series fleets.
Correct right-barrel displacement rebalances flow between left and right sections, restoring boom speed, arm speed and swing response simultaneously.
FAQ
Q: How to distinguish right-barrel wear from left-barrel or servo problems on PC200-8?
A: Perform a split-flow test: low right-section pump outlet pressure with normal left-section pressure, combined with high right case-drain flow, isolates the PC200-8-BDR barrel or valve plate as the failure.
Q: Can I install only the right barrel and reuse the existing valve plate?
A: Only if the right valve plate sealing face is within OEM flatness specification. Any scoring, heat marking or measurable surface steps require both barrel and valve plate to be replaced together.
Q: Is PC200-8-BDR interchangeable with PC200-7 right barrel?
A: No. PC200-7 and PC200-8 use different K3V112 sub-variants with different spline geometry. Always confirm the machine model is PC200-8 series before ordering.
Q: How to confirm this assembly fits my PC200-8 K3V112DT pump?
A: Verify pump model is K3V112DT and the right barrel position requires BDR. Provide pump serial number to our team for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
