PC200-7 boom slow or right-pump pressure unstable? A worn PC200-7 right cylinder block and valve plate generates increasing internal bypass that saps boom and arm force. RITO supplies this Tong Myung right barrel-and-valve-plate pair, lapped to K3V112DT OEM tolerances, to restore right-pump output on your PC200-7.

Spline bore and port timing verified for the PC200-7 K3V112DT variant, which differs from PC200-8 geometry. Using PC200-8 parts on a PC200-7 pump leads to incorrect sealing and rapid leakage.
Barrel valve face and valve plate lapped as a matched pair for immediate sealing efficiency - no break-in leakage period that temporarily reduces new-part performance.
Restoring right-barrel displacement recovers boom lift force and simultaneous boom-arm speed that degrades as the right section wears.
Cylinder bores honed to K3V112DT OEM clearance for correct volumetric efficiency across the PC200-7 operating pressure and temperature range.
FAQ
Q: What symptoms indicate the PC200-7 right barrel is failing?
A: Boom lift force progressively weakens, right-pump outlet pressure reads low on a split-flow gauge test, right-section case-drain flow exceeds OEM limit, and hydraulic oil temperature rises more quickly than normal.
Q: Is PC200-7-BDR interchangeable with PC200-8-BDR right barrel?
A: No. PC200-7 and PC200-8 use different K3V112DT sub-generations with different spline engagement. Always confirm your machine model is PC200-7 before ordering.
Q: How often should the K3V112DT pump barrel be replaced on PC200-7?
A: Service life depends on oil cleanliness and operating load. Perform case-drain flow tests every 2000-3000 hours. Replace barrel and valve plate when case drain exceeds OEM specification or bore clearance exceeds service limit.
Q: How to confirm PC200-7-BDR fits my PC200-7 K3V112DT pump?
A: Confirm machine model is PC200-7 series and pump generation is K3V112DT (PC200-7). 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.
