Swing that accelerates slowly, drifts after the lever is released or lets the upper structure creep on a slope usually means the 4625367-240 Excavator Hydraulic Swing Motor is worn. Internal bypass past the pistons and tired brake plates cut usable swing torque. RITO supplies this 4625367-240 Excavator Hydraulic Swing Motor for the Hitachi excavator excavator range to restore crisp swing response.

In Stock4625367-240 Excavator Hydraulic Swing Motor for the Hitachi excavator excavator range. The motor converts high-pressure oil flow into the starting torque required to rotate the upper structure, with integrated braking control, and its brake and relief arrangement controls how the upper structure stops. In service 4625367-240 are all found on closely related swing devices, so nameplate identification matters. Internal leakage past worn pistons is the usual reason swing torque falls away and the oil heats up, making assembly replacement the practical repair. RITO supplies it as a direct-fit service replacement; confirm the machine model, flange bolt pattern, shaft and port positions before ordering.

A matched cylinder block and piston set lets the {M} generate its rated starting torque again, so the upper structure accelerates without hesitation.
Correct piston fit and a healthy brake arrangement stop the upper structure from creeping on gradients, which keeps the operator in control during fine grading.
The {M} keeps the original flange bolt pattern, shaft and port positions, so it drops into the existing swing gearbox arrangement without adapters.
The motor is supplied with its relief and brake arrangement assembled, supporting smooth deceleration and reducing shock loads into the swing gearbox and slew ring.
FAQ
Q: Which excavators use the {M} swing motor?
A: The {M} is a Kawasaki M series swing motor used across the {cls} excavator range. The same motor family is built in several configurations, so confirm the machine model, flange bolt pattern, shaft and port positions against the motor being replaced.
Q: What are the common reference numbers for {M}?
A: Service identifications for this swing motor include {REFS}. The nameplate on the motor combined with the machine serial number is the most reliable way to confirm identity.
Q: What symptoms show the {M} swing motor is worn?
A: Typical signs are slow swing acceleration, reduced swing torque, drift or creep on slopes after the lever is released, rising case-drain flow, hot hydraulic oil and noise from the swing area.
Q: Is the {M} a swing motor or a main pump?
A: The {M} shown here is a hydraulic swing motor used in the upper-structure rotation device. It is not the excavator main hydraulic pump and not a control valve.
Q: How do I confirm the {M} fits my machine?
A: Check the flange bolt pattern and pilot diameter, the drive shaft or spline, the hydraulic port positions and the brake and relief arrangement against the removed motor. Matching all four confirms the correct service replacement.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
