Product Details
24V Isuzu starter solenoid switch
,OEM 8970256770 solenoid for NPR
,4HF1 NKNP engine solenoid switch
The Starter Solenoid Switch with OEM numbers 8-97025677-0 / 8970256770 is a direct-fit replacement for ISUZU NKNP / NPR trucks equipped with the 4HF1 diesel engine. This solenoid engages the starter pinion with the flywheel ring gear and closes the high-current circuit to crank the engine, serving as the critical interface between the ignition switch and the starter motor.
- OEM Cross-Reference Verified: Replaces 8-97025677-0, 8970256770, and cross-references to Hitachi 2240-4701, AS-PL SS2059, WAI 66-8179, Cargo 234868.
- Verified Specifications: 24V voltage, 3 terminals, 2 mounting holes, outer diameter approx. 52mm, net weight 0.78kg — confirmed against supplier technical data and cross-reference catalogs.
- Fitment Confirmation: Confirmed for ISUZU NKNP / NPR with 4HF1 engine — verified against multiple parts listings.
- Pre-Delivery Function Test: Each unit undergoes pull-in/hold-in coil continuity check and terminal insulation verification before packing — per in-house QC records (standard: 100% inspection before shipment).
- Single "clack" from the starter area when turning the key; engine does not crank.
- Starter motor spins but engine does not start (pinion not engaging).
- No sound at all from the starter when ignition is turned (open solenoid coil).
- Intermittent cranking — works sometimes, fails other times.
- Burning smell or visible damage at solenoid terminals.

| Feature | Benefit + Verification Signal |
|---|---|
| 24V coil rated for diesel applications | Correct pull-in force for 4HF1 starter engagement — verified by voltage specification. |
| Hitachi-compatible design | Direct interchange with Hitachi 2240-4701 — confirmed by cross-reference catalog. |
| 3-terminal configuration | Matches OEM wiring layout — verified against ISUZU NKNP/NPR application. |
| Sealed coil construction | Resists diesel engine bay heat and vibration — confirmed by supplier specification. |
| OEM-matched fitment | Direct bolt-on OEM hole pattern — no drilling or modification required. |

| QC Item | Verification Method |
|---|---|
| Pull-in coil continuity | Multimeter resistance check per unit |
| Hold-in coil continuity | Multimeter resistance check per unit |
| Terminal insulation | Megohmmeter test between terminals and housing |
| Mounting hole spacing | Caliper measurement against OEM specification |
| Plunger movement | Manual actuation check for smooth travel |
- Disconnect battery negative. Note terminal positions on old solenoid.
- Disconnect main battery cable (B+), starter control wire (terminal 50), and motor feed (if separate).
- Remove mounting bolts/screws securing the solenoid to the starter.
- Remove old solenoid; inspect plunger and contact disc for wear.
- Install new solenoid; reconnect terminals to original positions. Tighten B+ and motor terminals securely.
- Reconnect control wire and battery negative.
- Function test: Turn ignition key — verify a single firm engagement and engine cranking. Check for unusual noise.
Inspect solenoid terminals for corrosion at every oil change. Keep battery terminals clean and tight — low voltage is a common cause of solenoid failure. If intermittent cranking occurs, test control circuit voltage before replacing the solenoid.
| Brand | Model | Engine Code | Notes |
|---|---|---|---|
| ISUZU | FSR / FSR 500 | 6HE1 | Primary fitment per OEM number |
| ISUZU | FVR / FTR | 6HE1 (verify) | Some cross-applications reported; confirm by VIN |
- HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily fitment-oriented for ISUZU FSR 6HE1; the above numbers are listed for customer cross-comparison.
- If your vehicle is a Mitsubishi Fuso FK/FM with MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. The "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.
- Neutral carton / customer-specified packaging.
- Suitable for: wholesalers, repair shops, fleet maintenance.
