FAQ

Q1: How do I confirm this idler gear fits my Isuzu 4TNV94 engine?
A: First, verify your engine model is exactly 4TNV94 (check the engine data plate). Then, compare the physical dimensions (diameter, thickness, bore size) of your old gear with the OEM size specifications. If your engine is a variant like 4TNV94L or 4TNV94HT, this gear is typically compatible, but we recommend sending a photo of your old part for confirmation.

Q2: What are the signs that my idler gear needs replacement?
A: Common symptoms include unusual whining or knocking noises from the timing cover, engine misfiring due to timing drift, or visible wear (chipped teeth, pitting) on the gear surface. If you are replacing other timing components (like the timing belt or chain), it is prudent to inspect and replace the idler gear simultaneously.

Q3: Do I need to replace any other parts when installing this idler gear?
A: Yes, it is highly recommended to replace the idler gear bearing or bushing at the same time, as wear on the bearing can cause premature failure of the new gear. Additionally, always check and replace the gear retaining bolts and lock washers to ensure proper torque specifications are met.
