A: It runs stably within ‑42℃ to 102℃ under normal construction working conditions.

Q: Which mechanical position is this seal kit designed to fit?
A: It is mainly installed on rotating axle shaft assemblies of road roller machines.

Q: Does this full repair kit include backup rings and auxiliary small gaskets?
A: Yes, matched backup rings and auxiliary gaskets are supplied for complete overhaul service.

Q: How does this seal perform when exposed to gear oil and heavy‑duty lubricants?
A: Nitrile rubber keeps stable dimension, it resists swelling against mineral‑based lubricating fluids.

Q: What observable condition tells us that seals should be replaced?
A: Persistent hydraulic oil seepage around pump shaft housing, mixed with mine rock powder and tiny metal fragments around leak point.

Q: Can this oil seal kit fit torque converter assemblies of multiple wheel loader series?

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.
