4. FAQ

Q: What materials compose this oil seal kit?
A: The sealing lip is XNBR carboxylated nitrile rubber for superior wear resistance, and outer shell is galvanized stamped‑steel equipped with high‑strength helical garter spring.

Q: What practical installation suggestions should technicians follow during replacement?
A: Clean and polish shaft surface to remove fine burrs, apply thin uniform grease coating before pressing‑in; avoid sharp edges scratching sealing lip working surface.

Q: What performance improvements does zinc‑phosphate treatment bring for steel shell?
A: This surface treatment enhances shell wear resistance and rust‑proof capacity, adapting to narrow‑space working sites full of dust and muddy debris.

Q: What early‑stage abnormal symptoms indicate oil seals need to be replaced?
A: Watch for slow gear oil seepage at shaft end and intermittent low‑pitch buzzing noise when skid‑steer loader turns sharply or switches forward‑reverse direction frequently.

Q: What installation reminders should field technicians keep in mind?
A: Clean shaft surface thoroughly and remove micro burrs, apply thin uniform grease film before pressing‑in; avoid sharp tools damaging the working edge of sealing lip.

Q: What warehouse storage tips for unopened seal kits?
A: Keep in cool dry indoor zone. Avoid heavy stacking extrusion, sharp scratches and long‑time exposure to heat sources and ultraviolet rays.

Q: What practical working sign tells technicians to replace seals promptly?
A: Gradual grease seepage mixed with street sand and dust particles around brush‑drive housing indicates seal abrasion and gradual aging performance drop.
