4. FAQ

Q: Can this oil seal work steadily on rotating shaft assemblies?
A: Yes, the specially designed sealing lip fits rotary shafts to block internal lubricant leakage.

Q: Does this overhaul kit contain all sealing spare parts for full pump maintenance?

A: Yes, it includes main double‑lip shaft oil seal, multi‑size O‑rings, anti‑extrusion auxiliary shims and small sealing washers for complete pump overhaul work.

Q: What typical symptoms tell technicians the oil seals need to be replaced?
A: Hydraulic oil seepage from pump shaft end, unstable system pressure, intermittent rattling noise and insufficient output power in spraying operation.

Q: How should warehouse staff keep these sealing assemblies for long‑term stock?
A: Keep original packaging intact, avoid collision and deformation of metal shell, store in cool dry warehouse, stay away from heat source and oily chemical agents.

Q: What practical symptoms indicate differential shaft oil seals need replacement?
A: Gear lubricant leakage at differential shaft end, continuous oil loss, low‑frequency rumbling noise and abnormal power transmission during heavy‑load transportation.

Q: Are these oil seal kits manufactured according to standard installation dimensional specifications?
A: Each complete kit is precision sized to match standard shift‑shaft housing bore dimensions for backhoe loader assemblies.

Q: Will frequent forward‑reverse travel rotation accelerate abrasion of sealing lip?
A: Specially adjusted lip contact pressure reduces friction heat output, slowing lip wear under long‑term bidirectional rotary working cycles.

Q: What risk will scratch damage bring to electrophoretic coated shell?
A: Once the coating layer is scratched off, bare steel will corrode gradually, which may lead to seal loosening and unexpected oil leakage.

Q: How well can this full sealing kit block mud, gravel dust and hot gear oil mist on muddy outdoor road job sites?
A: The multi-layer flexible rubber lip scrapes thick mud off the shaft surface, the fully enclosed plated metal shell blocks coarse dust particles, and inner auxiliary rubber layers isolate high-temperature oil mist to protect internal precision gears.
