Q: Which machine assembly is this seal kit designed to repair?
A: It matches brake shaft assembly, preventing lubricant leakage at rotating brake shaft joint of wheel loader.

Q: Can these sealing components adapt frequent braking and start‑stop on rough job‑site ground?
A: Yes, it can handle repeated friction heat and impact vibration brought by frequent loading and unloading cycles.

Q: Does this kit contain all sealing accessories for one complete brake shaft overhaul?
A: Yes, it includes matched oil seals, garter springs and dust‑proof auxiliary washers for single‑unit service work.

Q: What temperature range can these sealing assemblies maintain stable sealing performance?
A: Reliable sealing effect from ‑24℃ up to 155℃ under high‑intensity outdoor operating environment.

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.
