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 complex operating conditions can this seal kit bear for track‑type excavator travel motor?
A: It resists frequent start‑stop impact load, mud and dust erosion, together with temperature rise generated during off‑road excavation and travelling work.

Q: Does this overhaul kit contain all sealing consumables for one full travel motor servicing?
A: Yes, main shaft lip oil seal, multi‑dimension O‑rings, anti‑extrusion backup rings and small auxiliary sealing washers are all provided within one kit.

Q: What practical operating symptoms tell technicians travel motor oil seals need replacement?
A: Hydraulic oil seepage at motor shaft end, weak travelling force, irregular clicking noise and unilateral slow moving speed during machine travelling.

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.
