- HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily intended for ISUZU FSR 6HE1 applications; 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" and "long" pushrod variants exist within the MC828264 family.
- Always provide your VIN/chassis number for verification. Do not rely solely on cross-reference numbers.
| QC Item | Verification Method |
|---|---|
| Overall length | Caliper measurement against OEM drawing |
| End radius / ball geometry | Visual and gauge check for wear or deformation |
| Straightness | Roll test on flat surface — reject if bent |
| Surface finish | Visual inspection for pitting, corrosion, or scoring |
| Weight consistency | Batch weighing (target: approx. 0.06 kg) |
- Disconnect the battery negative terminal. Remove the valve cover and associated components.
- Remove the rocker arm assembly (if required to access push rods).
- Carefully withdraw the old push rods — keep them in order by cylinder position for inspection.
- Check each push rod for straightness (roll on a flat surface) and wear at both ends. Replace any that are bent, pitted, or worn.
- Clean the push rod seats in the cylinder block and rocker arm sockets.
- Install new push rods in their original positions, ensuring proper seating in the lifter sockets.
- Reinstall the rocker arm assembly. Adjust valve clearance to workshop manual specification.
- Function test: Crank the engine by hand to verify smooth valve operation before starting. Run the engine and listen for abnormal valvetrain noise.
Push rods are not a routine maintenance item. Inspect them during any valvetrain service or if abnormal engine noise develops. Keep engine oil clean and at the correct level — contaminated oil accelerates push rod and lifter wear.
- Neutral carton / pallet / wooden case (per supplier standard)
- Suitable for: engine rebuild shops, wholesalers, fleet maintenance
