Q: What causes severe pressure drops and drifting when the excavator upper structure is parked?
A: Drifting is typically caused by worn internal swash plates or leaking relief valves within the motor assembly. This allows pressurized fluid to bypass the pistons, preventing the mechanical brake from holding properly.

Q: Is it necessary to pre-fill the motor housing with oil before starting the engine?
A: Yes. You must fill the motor case via the highest drain port before initial startup. Running the motor dry for even a few seconds will score the piston shoes and ruin the cylinder block.

Q: Do these hydraulic swing units include integrated pressure relief and anti-cavitation valves?
A: Yes, every unit comes with pre-set factory relief and anti-cavitation valves. This protection system dampens sudden pressure spikes during rapid operator movements.

Q: How does this hydraulic motor maintain consistent rotation speeds during freezing conditions?
A: The high-precision internal tolerances are designed to handle viscosity changes. Combined with low-friction coatings on the pistons, this design prevents seizing and ensures smooth rotation from -40°C to 120°C.
