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 different seal colours will I receive inside this repair package?
A: It includes black sealing lip, silver‑grey metal shell, tan backup rings and milky‑white auxiliary sealing components for hub installation positions.

Q: Does this kit contain all sealing pieces for full motor grader wheel hub disassembly service?
A: Yes, all matched oil seals and auxiliary sealing parts are prepared for field overhaul of motor grader wheel‑end hub assembly.

Q: What lubricant can these sealing assemblies work compatibly with?
A: It works steadily with high‑viscosity axle gear oil used for heavy‑duty motor grader travelling hub system.

Q: Are heavy‑duty mud‑proof wiper seals included within this repair set?
A: Wiper seals are supplied, blocking road mud, grit particles and splashing rainwater from invading internal hub cavity.

Q: What field working situations will speed up seal wear and aging?
A: Long‑time travelling on unpaved site roads, degraded gear lubricant and continuous mechanical vibration will shorten seal service life.

Q: Is this oil seal kit suitable for wheel hubs of multiple motor grader variants?
A: It is designed for dedicated shaft and bore dimensions, please verify dimension data before you confirm purchase orders.

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.
