FAQ

Q1: Is this crankshaft a direct bolt-on replacement for my Doosan DX130 excavator?
Yes, this crankshaft is designed as a direct replacement for the original Doosan 150107-00542C or 150107-00957 part. It is manufactured to OEM specifications and requires no modification for installation. However, we recommend confirming your engine model (Doosan D34) before purchasing.

Q2: What maintenance procedures are recommended during installation?
Ensure all bearing journals are cleaned and oiled before assembly. Use new main and rod bearings, and torque all bolts to the manufacturer’s specifications. After installation, prime the engine oil system before starting to prevent dry start damage. We recommend professional installation by a certified diesel mechanic.

Q3: How does this aftermarket crankshaft compare to the original Doosan part in terms of durability?
Our aftermarket crankshaft is manufactured from high-grade forged steel, similar to the OEM part. It undergoes rigorous quality control, including dynamic balancing and magnetic particle inspection. While it is a cost-effective alternative, its performance and durability are engineered to meet or exceed the original part’s lifespan under normal operating conditions.
