FAQ


Q: How can field mechanics adjust the load-sensing standby pressure on this 708-1U-00162 pump?
A: Mechanics can adjust the small adjustment screw on the pump compensator valve valve using a calibrated pressure gauge.
 
Q: What symptom indicates that the internal swashplate bearings of a backhoe loader pump have worn down?
A: Look for slow responses under load, increased engine drag, and fine brass flakes in the hydraulic filter.
 
Q: Are the suction and discharge port patterns on 708-1U-00162 identical across all European-spec WB97S lines?
A: Yes, the flange dimensions and bolt circles circle layouts follow standard European factory specifications for easy replacement.
 
Q: Why does this pump use a bimetallic cylinder face design rather than an all-steel assembly?
A: The bronze-faced design reduces friction friction and wear against the valve plate, preventing seizure during high-speed operation.
 
Q: What quality options are available?

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