Key Features and Market Reference
1. Performance Features
- High tooth surface hardness and strong wear resistance, reducing the risk of timing chain skip
- Built-in bushing/bearing structure, low rotational resistance, reducing noise in the timing system
- High dynamic balance accuracy, less prone to vibration at high speeds
Purchase and Installation Notes
- Code Verification: When purchasing,务必 verify 897112-6071 + 60311924. Distinguish idler gears for 4HK1/6WG1 models (different number of teeth and hole diameters).
- Replacement Recommendation: When performing engine overhaul or experiencing timing chain skip, abnormal noise, it is recommended to replace the idler gear shaft, bushing, and timing gears simultaneously to avoid timing deviation caused by wear.
- Installation Requirements:
1. Before installation, check tooth surface wear, pitting, and ensure smooth rotation of the bushing without jamming
2. Tighten the idler gear shaft bolts to the manufacturer-specified torque (approximately 50-60 N·m) to prevent loosening
3. After installation, recheck the timing to ensure alignment of gear marks at top dead center of cylinder one
- Fault Diagnosis: Engine abnormal noise, reduced power, timing chain skip are often caused by idler gear tooth surface wear or loose bushing, requiring timely replacement.
