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 features do the sealing assemblies inside the kit show?
A: Rubber sealing lips are matte black, and outer steel shell presents special amber‑brown anti‑corrosion coated surface.

Q: Does this kit carry all sealing components for one complete hydraulic pump overhaul?
A: Yes, it contains matched oil seals, high‑tension garter springs and anti‑extrusion backup rings for single pump overhaul work.

Q: What temperature scope can these sealing assemblies maintain normal sealing function?
A: Reliable sealing effect ranges from ‑24℃ up to 168℃ under harsh mine operating environment.

Q: What important installation suggestions should mechanics bear in mind?
A: Protect rubber lip from sharp shaft edges; do not distort or squeeze stamped steel shell while pressing seals into housing.

Q: How should warehouse operators handle long‑term stock preservation?
A: Keep goods in cool dry storage zone, avoid heavy stacking and thermal radiation to prevent rubber early deterioration.

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.
