High-strength alloy steel Idle Gear with case-hardened HRC 55-60 and precision-machined bore for Isuzu GXZ360 6UZ1-TCS Engine

The Idle Gear (OEM Numbers: 8-97430603-0 / 8974306030) is a premium-quality timing component designed for Isuzu GXZ360 heavy-duty trucks equipped with the 6UZ1-TCS diesel engine.

Idle gear transfers rotation between the crankshaft gear and the camshaft gear (or injection pump gear), maintaining correct timing direction and gear train tension. Ensures precise valve and injection timing for Isuzu 6UZ1-TCS engines.

• OE Quality: Manufactured to Isuzu dimensional and material specifications for perfect fit and reliable timing
• Precision Gear Teeth: Hobbed and ground for accurate tooth profile, quiet operation
• Case-Hardened: Surface hardness HRC 55-60 for exceptional wear resistance
• Precision Bore: Accurately machined for proper fit on idler shaft or bearing
• Restores Engine Timing: Eliminates timing noise, incorrect valve timing, and power loss
• Direct Replacement: Matches OE gear dimensions - simple bolt-on installation
• Cost-Effective: Affordable alternative to genuine OEM gears

This idle gear is specifically designed for Isuzu GXZ360 trucks with 6UZ1-TCS engine.

• ISUZU GXZ360 (heavy-duty truck, 6×4 or 8×4 configuration)
• May also fit other Isuzu models using the 6UZ1 engine (e.g., CYZ, CXZ) - verify compatibility

• 6-Cylinder, Inline Diesel, Turbocharged
• Displacement: 9.8L (approx. 9800cc)

Installation steps overview for timing gear train:

1. Remove front timing cover and any components blocking access
2. Remove the old idler gear (may require pulling the gear off the shaft)
3. Inspect the idler shaft and bearings - replace if worn
4. Clean the shaft and gear bore
5. Lubricate the new gear bore and idler shaft with engine oil
6. Install the new idler gear onto the shaft, ensuring alignment with crankshaft and camshaft gears
7. Install any retaining bolts or washers, torque to specification
8. Check timing marks alignment - rotate engine to verify correct timing
9. Reinstall timing cover and associated components
10. Start engine and listen for abnormal gear noise
