The Crankshaft Gear with OEM numbers 8-94394342-4 / 8943943424 is a verified direct-fit replacement for ISUZU LT132, FSR, FTR, FVR, and 700P trucks equipped with 6HE1T, 4HK1-TCS, 6HK1, and 6HH1 diesel engines. This gear (GEAR; CR/SHF) is the crankshaft timing gear, installed at the front end of the engine crankshaft. It engages with the timing chain or idler gear through 42 teeth to drive the camshaft and injection pump, ensuring precise synchronization of engine valve timing and fuel injection timing.
The crankshaft timing gear is continuously subjected to alternating loads and high-speed rotation. When gear teeth wear, pit, or fracture, it causes engine timing misalignment, leading to power loss, hard starting, and even severe valve-to-piston interference. Timely replacement restores proper engine timing system operation.

Crankshaft timing gear replacement involves engine timing system disassembly. Professional installation by a qualified technician using specialized tools is recommended. Thoroughly clean the crankshaft front end and gear mounting position before installation, ensuring no old gear residue or contaminants. A dedicated gear installation tool must be used, applying even pressure; never hammer the gear directly.
- Remove timing system: Remove timing chain/belt cover, disassemble timing chain or belt.
- Remove old gear: Use a gear puller to extract old crankshaft gear, taking care not to damage crankshaft front end.
- Clean mounting position: Thoroughly clean crankshaft front end and gear mounting position, removing old gear residue, oil, and rust.
- Install new gear: Use dedicated installation tool to press new gear evenly onto crankshaft front end, ensuring gear is fully seated.
- Install timing system: Install timing chain/belt per workshop manual method, aligning timing marks.
- Check timing: Confirm crankshaft and camshaft timing marks are aligned, timing is correct.
- Road test: Start engine, check for smooth operation, absence of abnormal noise, and confirm proper timing system operation.
- Every 50,000 km: Check timing system operation for abnormal noise.
- Every 100,000 km: Inspect timing chain/belt and gear wear; replace if necessary.
- When engine timing abnormality, power loss, or hard starting is detected: Inspect gear and timing system promptly.
