5. FAQ

Q: What are the core material traits of oil seal kit part number 455513?
A: Part number 455513 adopts nitrile‑butadiene rubber sealing lip and red‑coated treated steel shell. This material combination delivers good grease resistance and stable structural rigidity under long‑term road shock and hub rotating friction.

Q: What visual features do sealing components inside part number 455513 exhibit?
A: For part number 455513, rubber sealing lip presents smooth deep black surface, and the metal shell shows special reddish‑brown anti‑corrosion coating without extra paint spraying.

Q: Where is this oil seal kit installed on motor grader?
A: This seal kit fits into the clearance between rotating wheel hub and stationary axle spindle at the chassis wheel end position.

Q: What installation advice should mechanics follow during on‑site replacement?
A: Clean and polish shaft surface to remove fine burrs, spread thin uniform grease before pressing‑in; avoid sharp edges cutting sealing lip working surface.

Q: What real‑world benefits does Redicoat treatment bring for steel shell?
A: This coating improves shell bore‑fitting performance and rust resistance, adapting to muddy construction sites with mixed digging and travelling operations.

Q: How will this sealing kit interact with construction‑site lubricants?
A: Nitrile rubber keeps stable dimensional property and low‑swelling rate against transmission gear oil and conveyor bearing grease.

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.
