Key Features & Advantages


Large-Class Motor Rotating Group

Rotating group sized and rated for the higher swing torque demand of EC240B-EC360B class excavators, maintaining volumetric efficiency under sustained high-pressure swing duty.

Brake Valve EC240B-EC360B Calibration

Brake valve set-pressure matched to the EC240B-EC360B swing circuit deceleration characteristic, providing controlled swing stop without overswing that loads the large slew ring.

Standalone Motor Replacement

Motor-only unit allows gearbox to remain in service when gearbox inspection confirms it is serviceable, reducing repair scope and cost.

EC240B through EC360B Range

14673219 covers EC240B, EC250D, EC300D and EC360B for direct bolt-on replacement across Volvo 24-36 tonne swing motor flange specification.



FAQ

Q: How do I confirm the 14673219 motor has failed rather than the EC240B swing gearbox?
A: Measure motor case-drain flow at rated swing speed. Above OEM limit (typically 10-15 L/min for this motor class) confirms motor rotating group wear. Normal drain flow with gear noise indicates gearbox failure.

 

Q: What is the pre-fill procedure for 14673219?
A: Fill motor case with clean hydraulic oil through the case-drain port before connecting to the drain line. This prevents dry start that would immediately score the new rotating group.

 

Q: Does 14673219 fit EC360B without modification?
A: Yes. Confirm motor flange bolt pattern and port sizes match EC360B before ordering.

 

Q: How to confirm 14673219 fits my EC240B?
A: Match part number 14673219 and confirm machine is EC240B, EC250D, EC300D or EC360B. 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.
