Engine Camshaft 8943916760 8-94391676-0 for ISUZU FVZ FVR FTR FRR 6HK1 Diesel Engine — OEM Equivalent Direct-Fit Replacement with Induction-Hardened Cam Lobes
The Engine Camshaft with OEM numbers 8943916760 / 8-94391676-0 is a verified direct-fit replacement for ISUZU FVZ, FVR, FTR, and FRR vehicles equipped with the 6HK1 diesel engine. The camshaft is the core component of the engine valve train system, responsible for driving the intake and exhaust valves with precise timing, directly affecting intake efficiency, exhaust efficiency, and power output.
- ✓ Material & Heat Treatment Verified: Manufactured from Alloy Forged Steel, with cam lobes professionally quenched and hardened. Camshafts are induction-hardened to HRC 58-62, effectively preventing lobe flattening.
- ✓ OEM Cross-Reference Verified: Replaces ISUZU OEM numbers 8943916760 / 8-94391676-0; adjacent variant number 8-94391676-1 / 8943916761.
- ✓ Fitment Verified: Direct fit for ISUZU FVZ, FVR, FTR, FRR models with 6HK1 / 6HK1-TC diesel engines — cross-verified against ISUZU OEM parts catalog.
- ✓ 100% Factory Testing: All products undergo 100% testing before shipment.
- ✓ Installation Torque Verified: Camshaft gear tightening torque 142 N·m (14.5 kg·m / 105 lb ft); bearing cap bolt torque 27 N·m (2.8 kg·m / 20 lb ft) — per ISUZU 4HK1 & 6HK1 OEM workshop manual.
Indicating when camshaft replacement is needed:
- Insufficient engine power — Worn cam lobes reduce valve lift, decreasing intake air volume and combustion efficiency.
- Excessive fuel consumption — Camshaft wear causes valve timing deviation, misaligning fuel injection with intake air.
- Engine noise and valve knocking — Severely worn cam lobes or journals increase valve clearance, producing metallic knocking noise.
- Hard starting or unstable idle — Abnormal camshaft position sensor signal or valve timing misalignment prevents the ECU from correctly controlling ignition and injection.
- Black or white smoke from exhaust — Abnormal valve opening and closing timing causes incomplete combustion.

- Before ordering, verify that your original camshaft's lobe lift, journal diameter, and gear mounting position match the product.
- The 6HK1 and 6HK1-TC camshaft specifications are largely identical, but confirmation against the specific engine model is recommended.
- Ensure camshaft timing marks are correctly aligned per workshop manual during installation.
- For fitment confirmation, please provide VIN number or engine nameplate photo.
High strength and fatigue resistance, withstanding repeated loads at high RPM — suited for 6HK1 turbocharged diesel engine conditions.
Significantly improves cam surface hardness and wear resistance, preventing lobe flattening and extending valve train life.
Reduces friction against bearings, lowering abnormal engine noise and internal power loss.
Overall dimensions meet OEM specifications, requiring no additional machining, suitable for engine overhaul replacement.
Every unit undergoes full inspection before shipment, ensuring installation reliability and dimensional accuracy.

| 100% factory testing | Piece-by-piece dimensional and visual inspection |
Refer to ISUZU 6HK1 workshop manual for exact specifications:
- Rotate the crankshaft to bring No. 1 cylinder to compression TDC.
- Install camshaft bearing lower halves on the cylinder head; apply engine oil to bearing surfaces.
- Install the camshaft into the cylinder head, aligning the "•" mark (6HK1) with the upper face of the cylinder head.
- Install bearing caps with front marks facing the front of the engine, in numerical order.
- Tighten bearing cap bolts to specified torque: 27 N·m (2.8 kg·m / 20 lb ft), working from the center of the cylinder head toward the outside.
- Install camshaft gear and tighten to specified torque: 142 N·m (14.5 kg·m / 105 lb ft).
- Install rocker arm shaft assembly; adjust valve clearance.
- Install cylinder head cover.
- Inspect valve clearance and valve train noise every 40,000 km.
- Inspect camshaft wear at 80,000-100,000 km or upon power loss or abnormal fuel consumption.
- Under normal maintenance conditions, 6HK1 camshafts can exceed 200,000 km service life (varies by operating conditions and maintenance quality).
