FAQ

Q1: How do I confirm if this camshaft fits my specific Doosan engine?

A: Please verify your engine model (DB58 or DB58TIS) and the original part number on your existing camshaft. The numbers 65.04401-0018A and 65.04401-0018B are the direct OEM replacements. If you have a different number, please contact our sales team with your engine serial number for cross-verification.

Q2: What is the recommended installation procedure for this camshaft?

A: Installation should be performed by a qualified diesel mechanic. Key steps include: (1) Ensuring the engine is at Top Dead Center (TDC) for cylinder #1. (2) Carefully removing the old camshaft and inspecting cam bearings. (3) Lubricating the new camshaft lobes and journals with clean engine oil or assembly lube before installation. (4) Torquing cam bearing caps to the manufacturer’s specifications. (5) Re-timing the injection pump if disturbed. We recommend consulting the official Doosan service manual for your engine model.

Q3: What is the typical lifespan of this camshaft compared to the OEM part?

A: When installed correctly with proper lubrication and maintenance, this aftermarket camshaft is designed to meet or exceed the lifespan of the original Doosan part. In standard excavator applications, a lifespan of 8,000 to 12,000 hours is typical. Regular oil changes with the correct viscosity oil are critical to maximizing camshaft and overall engine life.
