Left-circuit travel or swing lagging on your PC200-8? A worn PC200-8 left cylinder block and valve plate allows left-section bypass to accumulate, robbing the travel and swing circuits of the flow they need for responsive simultaneous operation. RITO supplies this matched left barrel-and-valve-plate pair to restore PC200-8 left-pump output from installation.

In StockPC200-8 Cylinder Block with Valve Plate (Left) for Kawasaki K3V112DT piston pumps on PC200LC-8, PC210-8 and PC220-8 excavators. The left section barrel is the driven-side component governing the travel and swing priority circuits. Matched lapping between barrel face and valve plate ensures a sealing clearance that maintains rated volumetric efficiency across the full operating temperature range.

Left barrel bore wall geometry optimised for the driven-side position of the K3V112DT tandem pump, maintaining correct piston clearance under the slightly lower peak pressure of the left section.
Valve plate lapped to the barrel face as a pair, achieving Ra 0.1 sealing surface finish for immediate volumetric efficiency without a break-in leakage phase.
Correct left-barrel displacement restores the flow available for travel-priority and swing-priority logic, normalising simultaneous travel and swing operation.
Left barrel spline bore and port geometry confirmed for K3V112DT left-section position on PC200LC-8, PC210-8 and PC220-8.
FAQ
Q: How to identify a failing PC200-8 left cylinder block versus left servo failure?
A: Measure left-section case-drain flow at rated speed. Drain above OEM spec (typically 8-12 L/min) confirms left barrel wear. Normal case drain with low left-circuit pressure points to a servo or main relief valve issue rather than the barrel.
Q: What is the difference between PC200-8-BDZ left barrel and PC200-8-BDR right barrel?
A: BDZ is the driven-side left barrel governing travel and swing circuits. BDR is the drive-side right barrel governing boom and combined-load circuits. They differ in spline engagement and port orientation and are not interchangeable.
Q: Should I replace both left and right barrels together on PC200-8?
A: If total machine hours are high and one barrel is sufficiently worn to cause symptoms, the other is at similar wear life. Replacing both together at one service event eliminates a second major pump disassembly within a short period.
Q: How to confirm PC200-8-BDZ fits my K3V112DT pump?
A: Confirm machine model is PC200-8 series and pump model is K3V112DT. 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.
