FAQ


Q: Fault Diagnosis: What are the main signs that the 321706 swash plate is worn out or damaged?
A: Slow machine tracking response, failure of the pump to destroke at standby, and metal flakes in the hydraulic return filter. Grooves or scoring on the swash plate surface prevent the piston shoes from sliding smoothly, hindering displacement adjustments.
 
Q: Installation Standards: What critical checks must workshop mechanics execute when setting up a new swash plate assembly?
A: Check that the cradle bearings seat perfectly in the pump casing without any axial play. Mechanics must verify the smooth movement of the control piston links to ensure the swash plate tilts freely through its complete angular range.
 
Q: Procurement Verification: How can bulk parts managers differentiate the 321706 swash plate group from older design variations?
A: Check the part number plate and verify the exact diameter of the saddle bearing seats. The 321706 reference is optimized with enhanced oil-film retention grooves tailored specifically for the heavy-duty HPV140 model series pump.
 
Q: Extreme Environment Performance: How does this swash plate avoid structural failure during sudden high-pressure hydraulic hammer work?
A: It is forged from high-tensile alloy steel that undergoes specialized deep-induction hardening. This metallurgical structure prevents surface deformation and cracking under the violent shock loads typical of heavy concrete breaking and demolition shifts.
 
Q:  What quality options are available?

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