Q: My D155AX-6 is experiencing slow blade movement. Is the 708-7W-00140 pump the cause?
A: Slow movement usually indicates a drop in flow rate or pressure. If your pump is over 8,000 hours, internal wear in the cylinder block or piston shoes is likely. Replacing with a new 708-7W-00140 restores the hydraulic efficiency instantly.
Q: Why choose this Hydraulic Pump over a used one?
A: Our pumps feature an OEM-standard tri-metal structure and are trusted by repair shops & equipment fleets. A used pump often carries hidden internal fatigue that leads to failure within weeks, costing you more in labor and downtime.
Q: What is the lead time for 7087W00140?
A: We maintain ready-to-ship inventory. Typical express delivery via DHL or Fedex takes 3-7 business days depending on your locality.
