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 options do these sealing accessories have?
A: The main shaft seal is black rubber with dark grey metal shell, POM backup rings are off‑white, and matched O‑rings are deep black.
Q: Does this kit contain all sealing components for full final‑drive disassembly maintenance?
A: Yes, all matched sealing pieces are prepared for bulldozer onsite final‑drive system overhaul work.
Q: What grade of gear oil is suitable for these sealing assemblies?
A: It works reliably with high‑viscosity final‑drive gear oil widely used for heavy‑duty bulldozer equipment.
Q: Are heavy‑duty external dust‑excluding wiper seals included inside this set?
A: Wiper seals are supplied, which block mud, rock dust and grit from invading final‑drive internal cavity.
Q: What harsh site conditions will reduce the service lifespan of these sealing parts?
A: Long‑time muddy construction operation, degraded gear lubricant and sustained high drive‑housing temperature will accelerate seal deterioration.
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.
