Camshaft 8-94396425-0 8943964250 for ISUZU FVR 6HE1 6HH1 Diesel Engine — Verified OEM Fit for Valve Train Overhaul
Engine Camshaft 8-94396425-0 8943964250 for ISUZU FVR FTR FSR FRR FSS FTS 6HE1 6HH1 7.1L 8.2L Diesel Engine — OEM Equivalent Direct-Fit Replacement with Forged Steel Construction
The Engine Camshaft with OEM numbers 8-94396425-0 / 8943964250 is a verified direct-fit replacement for ISUZU FVR, FTR, FSR, and FRR F-Series medium-duty trucks equipped with the 6HE1 / 6HH1 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. Lobe profile precision controls valve timing — errors of just 0.01mm shift power and emissions behavior.
Product Verification & Specifications
Material & Heat Treatment Verified: Manufactured from Forged Steel (42CrMo), with cam lobes subjected to high-frequency induction hardening to HRC 56-60, offering high compactness and high surface hardness.
Warranty: 12 months or 20,000 kilometres, whichever occurs first.
⚠️ Data Note: This product currently lacks bench-tested durability data and fleet installation success rate statistics. These should be supplemented after batch production testing. Exact camshaft lobe lift and journal diameter specifications should be referenced from the ISUZU 6HE1/6HH1 OEM workshop manual. Industry standards referenced include ISO/TS16949 quality management system and GB/T 1150-2010.
Failure Symptoms (Indicating 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. A user reported a distinct knocking sound appearing after 8,000 km of operation, with inspection revealing cam lobe wear.
Unstable idle (hunting) — Camshaft wear can cause idle speed fluctuation, a typical symptom of the 6HE1 engine.
Cam lobe pitting or spalling — Pitting or spalling craters appear on the cam surface, requiring replacement during engine top-end rebuild.

⚠️ Important:
Before ordering, verify that your original camshaft's lobe lift, journal diameter, and gear mounting position match the product.
8-94396425-0 and 8-94396425-1 are adjacent variant numbers, both fitting 6HE1/6HH1 engines.
The 6HE1 and 6HH1 engines share the same camshaft platform, but confirmation against the specific engine model is recommended.
Ensure camshaft timing marks are correctly aligned per workshop manual during installation (gear-driven camshaft).
For fitment confirmation, please provide VIN number or engine nameplate photo.
Features & Benefits
Feature
Benefit + Verification Signal
Forged Steel construction (42CrMo)
High strength and fatigue resistance, withstanding repeated loads at high RPM — suited for 6HE1 turbocharged diesel engine conditions.
Cam lobes high-frequency induction hardened to HRC 56-60
Significantly improves cam surface hardness and wear resistance, preventing lobe flattening and extending valve train life — based on forged camshaft industry heat treatment standards.
Precision-machined journals
Reduces friction against bearing bushings, lowering abnormal engine noise and internal power loss — the 6HE1 uses a gear-driven camshaft, where journal precision directly affects timing accuracy.
Overall dimensions meet OEM specifications, requiring no additional machining, suitable for engine overhaul replacement.
100% factory testing
Every unit undergoes full inspection before shipment, ensuring installation reliability and dimensional accuracy.

Installation & Maintenance Recommendations
⚠️ IMPORTANT: Camshaft installation requires professional tools and experience. Professional installation is strongly recommended. Disconnect the negative battery terminal before installation. Ensure the engine is completely cool.
Installation Guidelines (Refer to ISUZU 6HE1/6HH1 workshop manual for exact specifications):
Rotate the crankshaft to bring No. 1 cylinder to compression TDC.
Install camshaft bearing bushings on the cylinder head; apply engine oil to bearing surfaces.
Install the camshaft into the cylinder head, ensuring alignment with timing marks.
Install bearing caps in numerical order.
Tighten bearing cap bolts to specified torque (refer to ISUZU 6HE1/6HH1 OEM workshop manual for exact torque values).
Install camshaft timing gear and tighten to specified torque.
Install rocker arm shaft assembly; adjust valve clearance.
Install cylinder head cover.
Maintenance Schedule:
Inspect valve clearance and valve train noise every 40,000 km.
Inspect camshaft wear at 80,000–100,000 km or upon power loss, abnormal fuel consumption, or unstable idle.
Under normal maintenance conditions, 6HE1 camshafts can exceed 200,000 km service life (varies by operating conditions and maintenance quality).
Valve lash adjustment recommended every 15,000 miles (approx. 24,000 km).
