FAQ
Q: What symptoms indicate the 21N-26-00120 swing motor needs replacing on a PC1250-8?
A: Swing speed progressively slower, cab overswings on deceleration, motor case-drain flow above OEM spec, and oil leaking from the swing motor seals.
Q: Does the 21N-26-00120 assembly include the swing gearbox?
A: This is the swing motor assembly. The reduction gearbox is a separate unit; confirm which component requires replacement before ordering.
Q: What is the pre-fill procedure for the 21N-26-00120 swing motor?
A: Fill the motor case with clean hydraulic oil through the case-drain port before connecting, preventing dry start that scores the new rotating group.
Q: How to confirm 21N-26-00120 fits my PC1250-8?
A: Match the motor flange bolt pattern and port sizes. Provide the machine serial number to our team for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
