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 materials make up this oil seal repair kit?
A: It consists of nitrile rubber sealing lip and cold‑rolled steel shell, delivering good compatibility with high‑temperature hydraulic oil and asphalt‑mixed dust on paving sites.

Q: What color can I see from these sealing assemblies?
A: The rubber sealing portion is deep black, and the outer steel shell shows natural silver‑grey metallic finish without extra paint coating.

Q: Which key assembly of the machine does this kit apply to?
A: It matches hydraulic pump input shaft assembly, preventing hydraulic oil leakage at the rotating shaft end of asphalt paver main pump.

Q: Are these seals suitable for long‑time continuous paving working conditions?
A: Yes, it resists sustained vibration and frequent pressure fluctuation generated during continuous road paving operations.

Q: Does this kit contain all sealing pieces needed for one hydraulic pump overhaul?
A: Yes, it includes complete oil seals, coil garter springs and anti‑wear backup rings for single pump maintenance service.

Q: What temperature range can these sealing components keep stable sealing performance?
A: It maintains reliable sealing capacity from ‑26℃ up to 132℃ under outdoor high‑temperature road construction environment.

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.
