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 color will these sealing components show when delivered?
A: Rubber sections are solid black, and metal shell shows natural silver‑grey metallic tone.

Q: What temperature range can this seal handle during long‑time site operation?
A: It can work reliably from ‑41℃ up to 108℃ under regular heavy‑load working circumstances.

Q: Which key position of machinery is this oil seal kit designed to fit?
A: It is mainly installed on transmission rotating shaft assemblies of wheel excavator equipment.

Q: Are matching backup rings and small auxiliary gaskets contained inside this kit?
A: Yes, supporting backup rings and assorted gaskets are included for full transmission overhaul.

Q: How does this seal perform when exposed to transmission fluid and heavy‑duty grease?
A: Nitrile rubber maintains stable dimension, with low swelling against common mineral‑based lubricants.

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?
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.
