,OEM hub inner seal 4208040740
,JAC N75/N80/N120 inner seal
The Rear Wheel Inner Oil Seal with OEM number 4208040740 is a verified direct-fit replacement for JAC N56 / N75 / N80 / N120 light truck models. It is a critical sealing component positioned on the inner side of the rear hub assembly, responsible for retaining bearing lubricant and preventing contaminants from entering the inner hub and bearing area.
How It Works: The inner seal is press-fitted into the hub or axle housing on the inboard side of the bearing. Its lip maintains contact with the rotating surface to retain grease or oil while excluding dust and water. A failed inner seal causes lubricant loss toward the axle or differential side, leading to bearing starvation and eventual hub damage.
- Real Bench Test Data: Seal lip contact pressure and operating temperature range verified via in-house bench test against OEM specification.
- Proven Durability: Rated for extended service life under normal operation, based on fleet tracking data.
- Installation Success Rate: 100% direct press-fit installation confirmed across repair orders for JAC N56 / N75 / N80.
- OEM Cross-Reference Verified: Directly replaces OEM 4208040740.
- Material Verification: NBR lip with steel case, verified by material test report.
- Oil or grease leakage visible on the inner side of the rear hub or axle area
- Differential or axle oil level dropping faster than normal
- Grinding or humming noise from the rear hub bearing due to lubricant loss
- Contaminated lubricant (metal particles, water ingress)
- Premature bearing wear requiring hub disassembly

⚠️ Important Fitment Notes:
HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily oriented toward ISUZU FSR 6HE1 fitment; the above numbers are listed for customer cross-comparison.
If your vehicle is a Mitsubishi Fuso FK/FM with an MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. Both "short" and "long" pushrod variants exist within the MC828264 family.
Always provide the VIN or chassis number for verification. Do not rely solely on cross-reference numbers.

| Oil resistance test | ASTM D471 standard |
| Visual inspection | 100% factory check for lip defects and case damage |
⚠️ IMPORTANT: Use a proper seal driver to avoid lip damage. Lubricate the lip with clean bearing grease before fitting.
- Clean the hub bore and shaft surface; remove the old seal and inspect for scoring.
- Apply clean lubricant to the new seal lip and hub bore.
- Position the seal squarely and press in with a seal driver until fully seated.
- Reassemble hub and axle components per manual torque specifications.
- Check lubricant level and inspect for leaks after a short test drive.
Inspect the rear hub area for leakage at regular service intervals. Replace the seal if leakage is detected; do not reuse a removed seal.
- Individually packed in plastic bag and carton; custom packaging available (MOQ applies).
- Suitable for auto parts wholesalers, repair shops, and fleet procurement.
