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 installation tips should field repair technicians pay close attention to?
A: Avoid scratching composite rubber lip by sharp shaft edges; do not deform stamped steel shell during pressing‑in fitting process.
Q: How should distributors carry out long‑term storage of these spare seal kits?
A: Store in dry and ventilated storage area, avoid heavy goods stacking and high‑temperature surroundings to slow rubber aging.
Q: What obvious visible symptom suggests carrying out seal replacement?
A: Gradual fluid seepage at brake shaft joint, mixed with sand and fine soil accumulated around the leaking area.
Q: Is this seal kit suitable for other loading‑type construction machines?
A: It is specially developed for wheel loader brake shaft structure; cross‑model installation is not recommended.
Q: Can this oil seal kit fit torque converter assemblies of multiple wheel loader series?
A: It is manufactured for fixed shaft and bore dimensions, please confirm dimension specifications before placing purchase orders.
Q: What abnormal conditions indicate oil seals should be replaced?
A: Lubricant leaks out from conveyor drive shaft end, conveyor runs unevenly, periodic scraping noise occurs and drive housing produces obvious over‑heat during paving work.
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.
