Travel or swing sluggish on your PC200-7 despite good engine power? A worn PC200-7 left cylinder block allows left-section bypass to drain away the flow that drives travel and swing circuits. RITO supplies this Tong Myung left barrel-and-valve-plate pair in the PC200-7 K3V112DT specification to restore left-pump output and simultaneous operation balance.

In StockPC200-7 Cylinder Block with Valve Plate (Left) for Kawasaki K3V112DT piston pumps on PC200LC-7, PC220-7 and PC220LC-7 excavators. The left barrel is the driven-side component, managing travel and swing priority flow. PC200-7 K3V112DT left-barrel port geometry is generation-specific and must not be substituted with PC200-8 parts.

Port timing and spline engagement verified for the PC200-7 K3V112DT left-section variant, preventing the sealing mismatch that occurs when PC200-8 barrels are used on PC200-7 pumps.
Correct left-barrel displacement restores travel-priority flow so the PC200-7 can simultaneously travel and dig without the travel circuit starving the swing or boom.
Surface lapping between barrel face and valve plate to Ra 0.1 ensures no break-in efficiency loss immediately after installation.
Confirmed fit for PC220-7 and PC220LC-7 in addition to PC200-7, covering three models with a single part number.
FAQ
Q: How to tell if the PC200-7 left barrel is failing rather than the right?
A: Low travel speed or unequal left-right travel with normal boom function, high left-section case-drain flow, and slow swing start-up all indicate left-barrel wear rather than right-section failure.
Q: Can the PC200-7-BDZ barrel be used in a PC220-7 without modification?
A: Yes. PC200-7, PC220-7 and PC220LC-7 share the same K3V112DT left-barrel specification. No modification is required.
Q: What is the correct hydraulic oil for K3V112DT on PC200-7 after barrel replacement?
A: Komatsu PC200-7 specifies ISO VG 46 anti-wear hydraulic oil. Replace the return-line filter element and pilot filter element before start-up to protect the new barrel from residual debris.
Q: How to confirm PC200-7-BDZ fits my K3V112DT pump?
A: Confirm machine is PC200-7 generation and pump is K3V112DT. Do not substitute with PC200-8 parts. Contact our team with the pump serial number for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
