4. FAQ
Q: Which hydraulic fluid types are compatible with this pump oil seal kit?
A: It works well with anti‑wear mineral hydraulic oil and common industrial hydraulic fluid used for large‑sized excavator main pump assemblies.
Q: What leakage problems can this seal kit help solve during pump maintenance?
A: It can improve shaft‑end external oil seepage and minor joint‑surface permeation, stabilizing pump output flow in long‑time site operation.
Q: What key installation points should mechanics notice during pump overhaul?
A: Keep assembly area free of dust and metal debris, avoid sharp edges scratching seal lip, coat thin layer of clean hydraulic oil before assembling every sealing piece.
Q: What function do PTFE backup rings perform inside this kit?
A: PTFE backup rings prevent rubber sealing elements from being squeezed out under high system pressure, extending overall service life of the whole repair kit.
Q: What early‑stage failure signals remind us to replace pump oil seals?
A: You may observe oil seepage at pump shaft end, slow machine action response and abnormal faint buzzing noise when pump runs at high‑speed rotation.
Q: What reference information do you require for project‑based bulk purchase?
