FAQ


Q: When should a fleet mechanic replace a DH225-7 swing motor rear cover rather than the whole motor?
A: If the swing motor works fine but you find oil leaking from the top cap, stripped mounting threads, or visible hairline cracks on the casing, replacing just the K9002105 cover is ideal. This targeted repair fixes the issue perfectly while saving your company hundreds in parts costs.
 
Q: What technical steps must be followed when sealing this K9002105 back cover?
A: Ensure the motor’s mating surface is clean and free of old seal residue. Always use a new manufacturer-specified O-ring, lubricate it slightly with clean hydraulic oil, and tighten the mounting bolts in a star pattern using a calibrated torque wrench to prevent uneven loading.
 
Q: How do international procurement managers confirm this end cap matches their specific crawler fleet?
A: Cross-reference your catalog with part number K9002105 and check the machine series: DH220-5, DH220-7, or DX225. Because internal valve configurations can vary by production year, sharing a photo of your motor data plate with our engineers helps prevent ordering mistakes.
 
Q: Can this motor cap withstand sudden pressure spikes caused by sudden swinging stops on slopes?
A: Yes, the thick-walled casting is engineered to handle massive relief valve backpressure surges. It resists structural flexing and distortion even when the excavator stops abruptly while carrying a fully loaded bucket on steep inclines.
 

Q: What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
