Case Excavator Hydraulic Parts: CX Series
Case excavator hydraulic parts for CX series machines, from 13-ton units to the 50-ton class. We stock main pumps, travel motors, swing motors, travel gearboxes, control valves and seal kits, in five grades: RITO, genuine, rebuild, OEM, aftermarket.
The CX210, CX230 and CX240 run a double axial piston variable pump, two rotating groups in one housing under a single Case part number. Buyers order one pump and expect one, then find two rotating groups inside and assume the wrong unit was shipped. It is the correct unit, and replacing only the failed side is how a rebuilt pump comes back within a season.
Case model to part cross reference
- CX130, CX160, CX210, CX210B, CX240: main pump KRJ6199
- CX210, CX240: main pump KBJ2789
- CX210, CX230, CX240: double axial piston variable pump, two rotating groups
- CX series with dozer blade: hydraulic circuit differs, confirm before ordering
Two pump numbers circulate for the same CX210 and CX240, KRJ6199 and KBJ2789, and sellers apply them to overlapping model lists. We confirm by machine serial rather than by the model name alone. For CX50, CX80, CX135, CX250, CX290, CX350 and CX490, send the serial number and we will place it against the right assembly.
The CX series is Kawasaki-based, so the pump is often easier to identify from the pump plate than from the Case number. Send a photo of the plate and we will cross it back. Main pumps are listed under excavator main pump.
We have supplied Case hydraulic components since 2003, are an authorised TongMyung distributor, hold CE certification MTL23112100304R01, and ship a test report with every unit.
