Regulator spring and spool pre-set to JCB JS200-series engine torque curve, preventing engine overload during full-power simultaneous boom and swing operation.
New cylinder block, pistons, piston shoes and valve plate restore K3V112 OEM volumetric efficiency, reducing fuel consumption and cycle time back to JS200 factory specification.
Pump regulator variant selected for JCB JS200 LS circuit pressure differential and flow-sharing specification, preventing the standby pressure hunting that occurs with generic K3V112 pumps.
Single pump covers JS200, JS200LC, JS210 and JS220 with the K3V112 specification common to this JCB series.
FAQ
Q: How do I confirm the JS200 K3V112 pump is the source of system flow loss?
A: Test both section case-drain flows at rated engine speed. Both above OEM spec simultaneously confirms rotating group wear. Isolated high drain from one section may indicate a valve or relief circuit fault rather than the pump.
Q: What should I flush before fitting the new JS200 K3V112 pump?
A: Drain the hydraulic tank, clean the interior, replace all filter elements including the suction strainer, refill with fresh hydraulic oil, and run at low pressure for 30 minutes before applying full load.
Q: Does the JS200-YYBZC pump include the coupling and drive plate?
A: The pump assembly is the pump only. Inspect the existing coupling for wear before reuse; replace if it shows imbalance or wear to protect the new pump bearings.
Q: How to confirm this pump fits my JS200?
A: Confirm machine model is JS200, JS200LC, JS210 or JS220 and that the existing main pump is K3V112 series. Provide machine 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.

Swing arc rough or slew ring leaking on your SK135SR-2? A worn YY06-20708 93-tooth slew ring develops ball groove pitting that creates vibration during rotation and allows abrasive ingress through a deteriorated seal. RITO's slew ring restores smooth, sealed swing operation on your compact SK135SR-2.

Track motor delivering low tractive force or the machine dragging one track? A worn TM22 series travel motor loses volumetric efficiency as barrel and piston shoes wear, reducing shaft torque output below what the machine needs on grades. RITO's TM22 travel motor assembly restores rated torque and full bilateral travel capability.

JCB JS130 or JS150LC actuators hunting or one function completely inoperative? A worn JS130FPF control valve loses spool metering accuracy, causing the flow-sharing system to lose priority balance and making smooth combined-function operation unpredictable. RITO supplies this precision control valve to restore correct metering and flow prioritisation across all JS130-series functions.

Pilot pressure low or auxiliary circuit losing flow on your excavator? A worn CBTLYB-F412.5 gear pump loses internal clearance, allowing slip flow to grow until pilot or charge circuit demand cannot be met. RITO supplies this heavy-duty CBTLYB-series gear pump to restore rated pilot or auxiliary flow for reliable main valve and circuit control.
