The Water Pump with OEM number 8-94376863 / 8943768630 is a verified direct-fit replacement for Isuzu C240 and C240PKJ diesel engines, commonly found in Komatsu, TCM, and Hyster forklifts as well as Isuzu Elf trucks and Journey buses. This centrifugal pump is the core of the cooling system, responsible for circulating coolant through the engine block and radiator to maintain optimal operating temperature.
- Quality Process Verified: 100% leakage tested before shipment, based on the manufacturer's standard QC protocol.
- Material Durability: Cast iron housing construction provides reliable heat resistance under continuous diesel operation, verified by industry-standard material specification for C240 applications.
- Interchange Coverage Verified: Cross-referenced against multiple OEM and aftermarket numbers including 5136101690, 5136101693, 8973798070, and 5-13610-169-3, confirmed via multi-source parts catalog matching.
- Fitment Confirmation: Direct bolt-on replacement for C240 series engines without modification, based on catalog compatibility data across forklift and truck applications.
- Coolant leakage at the pump weep hole or seal area
- Rapid engine temperature increase during normal operation
- Abnormal grinding or whining noise from the front of the engine (bearing wear)
- Coolant level dropping without visible external leaks
- Fan rotates but coolant does not circulate (impeller failure)
| Feature | Benefit + Verification Signal |
|---|---|
| Cast Iron Housing | Withstands high-temperature diesel cycles without deformation, verified by material specification for C240 heavy-duty use. |
| 100% Leakage Tested | Reduces risk of premature coolant loss after installation, verified by the manufacturer's stated end-of-line QC process. |
| Multi-Port Flow Design | Ensures consistent coolant circulation under prolonged operation, verified by standard C240 pump configuration. |
| Wide Interchange Coverage | Replaces multiple OEM numbers, simplifying sourcing for mixed fleets, verified against cross-reference catalogs. |
| 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 that primarily appear in Mitsubishi Fuso brake booster catalogs. This product is primarily intended for the ISUZU FSR 6HE1 application; the numbers above 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 your VIN/chassis number for verification. Do not rely solely on cross-reference numbers.
| QC Item | Verification Method |
|---|---|
| Leakage Test | 100% individual testing before packaging |
| Housing Integrity | Visual and dimensional inspection per ISO 9001 process (manufacturer claim) |
| Bearing Rotation | Manual rotation check for binding/noise (per Isuzu service manual guidance) |
| Material Hardness | Cast iron specification compliance (ASTM/industry standard for C240 pumps) |
Allow the engine to cool completely before removal. Use a new gasket (if included) and never over-torque mounting bolts to avoid cracking the cast iron housing.
- 1Drain coolant and remove the drive belt.
- 2Remove the fan and pulley from the old pump (retain hardware if reusable).
- 3Unbolt the old pump; clean the mating surface on the engine block.
- 4Install the new pump with a fresh gasket; torque bolts in a cross pattern to manufacturer specification (refer to the Isuzu C240 service manual).
- 5Reinstall the pulley and fan; check belt tension and alignment.
- 6Refill with the correct coolant; run the engine and check for leaks.
- Inspect coolant level and condition every 250 hours or monthly for industrial use.
- Replace coolant per Isuzu interval recommendation.
- Check the pump for weep/leak and bearing noise at every major service.
