FAQ

Q1: Is this idler gear a direct replacement for the Doosan 65.04505-5008A?

Yes, this part is manufactured to match the OEM specifications of 65.04505-5008A. It is a direct drop-in replacement for Doosan D2366 and DE12 engines. No modifications are required, but we recommend verifying the tooth count and bore size against your original gear.

Q2: What are the signs of a worn idler gear that needs replacement?

Common symptoms include excessive timing gear noise (whining or rattling), visible tooth wear or pitting, metal particles in the engine oil, and potential engine timing drift leading to poor performance or hard starting. If you notice any of these, inspect and replace the idler gear immediately to avoid catastrophic engine damage.

Q3: Do I need to replace any other parts when installing a new idler gear?

Yes, we strongly recommend replacing the idler gear bearing/bushing and the timing gear set (camshaft gear and crankshaft gear) if they show signs of wear. Always use new bolts and gaskets for reassembly. Proper torque specifications (refer to the engine service manual) are critical for correct gear alignment and engine timing.
