- 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. "Short" vs "long" pushrod variants exist within the MC828264 family.
- Always provide VIN/chassis number for verification. Do not rely solely on cross-reference numbers.
| QC Item | Verification Method |
|---|---|
| Thread size | Thread gauge check (target: M55) |
| Outer / inner diameter | Caliper measurement (target: 92mm / 53mm) |
| Height | Micrometer check (target: 10mm) |
| Thread integrity | Visual inspection for burrs, stripping, or damage |
| Material hardness | Sample batch check |
- Safely raise and support the vehicle. Remove the rear wheel and brake drum as needed.
- Clean axle spindle threads and bearing surfaces. Inspect the bearing for wear — replace if necessary.
- Install the hub/bearing assembly onto the spindle.
- Adjust bearing preload per ISUZU workshop manual specification. Reference torque values for similar ISUZU rear hub nuts: initial seating ~68 N·m, then final adjustment per manual.
- Install a new lock nut. Tighten to the specified torque while rotating the hub to seat the bearings.
- Stake or lock the nut to prevent rotation.
- Verify the wheel rotates smoothly with no play. Check for leaks before road test.
Inspect the rear hub area for grease leakage and wheel play at every brake service or every 20,000–30,000 km. If bearing noise develops, replace the bearing and nut together. Never reuse a removed lock nut — always install a new one.
- Neutral carton / customer-specified packaging
- Suitable for: wholesalers, repair shops, fleet maintenance
