FAQ
Q: How to confirm 706-7G-03090 motor needs replacing on PC200-8?
A: Measure motor case-drain flow at rated swing speed. Above OEM spec (typically 8-12 L/min) confirms motor wear. Normal drain with gear noise confirms gearbox failure.
Q: What is the pre-fill procedure for 706-7G-03090?
A: Fill motor case with clean hydraulic oil through the case-drain port before connecting the drain line to prevent dry start.
Q: Does 706-7G-03090 fit PC210-8 without modification?
A: Yes. Confirm motor flange bolt pattern and port sizes match PC210-8 before ordering.
Q: How to confirm 706-7G-03090 is correct for my PC200-8?
A: Match part number 706-7G-03090 and confirm machine is PC200-8, PC210-8 or PC220-8. 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.
