5. FAQ

Q: What construction machine does part number 07440-68730 oil seal apply to?
A: Part number 07440-68730 oil seal is specially produced for bulldozer hydraulic steering motor shaft overhaul and hydraulic oil leakage fixing.

Q: What raw materials are used to make the 07440-68730 oil seal?
A: 07440-68730 oil seal uses heat and oil resistant FKM rubber sealing lip together with metal stamping shell, keeping good sealing elasticity under continuous rotation and pressure cycling.

Q: What core function does this oil seal undertake?
A: It seals the gap between rotating steering motor shaft and motor housing, retains hydraulic oil inside the steering motor and blocks fine dirt from damaging internal rotor components.

Q: Where is this oil seal installed on the bulldozer?
A: It fits into the shaft bore on the output end of bulldozer hydraulic steering motor and surrounds the rotary power shaft.

Q: What working load and environment can this oil seal withstand?
A: It maintains stable sealing under frequent steering rotation and temperature changes when bulldozer adjusts direction repeatedly on dusty construction sites.

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.
