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: What color features can I find for each sealing component in this kit?
A: Main shaft oil seal is black rubber with reddish‑brown metal housing, PU auxiliary washers are light beige and assorted small O‑rings are solid black.
Q: What kinds of working environment can this seal kit withstand for motor grader gear pump?
A: It copes with frequent pressure fluctuation, mechanical vibration and moderate heat generation during long‑time road‑grading operation under open‑air conditions.
Q: Does this overhaul kit contain all sealing consumables for full gear pump disassembly maintenance?
A: Yes, main shaft lip oil seal, multi‑size O‑rings, anti‑wear auxiliary washers and tiny sealing shims are all packed inside one repair kit.
Q: What practical operating symptoms indicate gear pump oil seals should be replaced?
A: Hydraulic oil seepage from pump shaft end, unstable system pressure, obvious buzzing noise and insufficient hydraulic power when adjusting grader working blade.
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.
