Standalone motor design allows replacement without disturbing the EC210B swing gearbox when gearbox inspection confirms it remains serviceable.
14550091 covers EC210B, EC210BL, EC210 and EC240B for direct bolt-on replacement on EC210-series swing gearbox input flanges.
FAQ
Q: How do I confirm the 14550091 motor needs replacing rather than the gearbox on EC210B?
A: Test motor case-drain flow at rated swing speed. Above OEM spec confirms motor rotating group wear. Normal drain flow with gear noise indicates gearbox failure.
Q: What is the case-drain pre-fill procedure for 14550091?
A: Fill motor case through the case-drain port with clean hydraulic oil before connecting to the drain line. This prevents dry-start scoring of the new rotating group.
Q: Is 14550091 the same as 14552686 for EC210B?
A: Both part numbers apply to EC210-series swing motors. 14550091 is confirmed for EC210B with M5X130 motor; 14552686 applies to EC210C. Confirm the machine model before ordering.
Q: How to confirm 14550091 fits my EC210B?
A: Match part number 14550091 and confirm machine is EC210B or EC240B. 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.
