FAQ

Q1: How can I be sure this D1803 crankshaft will fit my engine?
A: This crankshaft is manufactured to standard OEM specifications for the Kubota D1803 engine. To ensure a perfect fit, we recommend checking the part number cast into your existing crankshaft (e.g., 1G865-23010) against our cross-reference list. Additionally, verify the number of main bearing journals and the flywheel bolt pattern on your old part.

Q2: What maintenance is required when installing a new crankshaft?
A: Installation of a new crankshaft is a major engine overhaul procedure. We strongly recommend replacing the main bearings, thrust washers, and connecting rod bearings at the same time. Ensure the crankshaft is properly lubricated with assembly lube before installation. All bearing journal surfaces must be perfectly clean and oiled. Torque all main bearing cap bolts to the manufacturer’s specifications using a calibrated torque wrench.

Q3: What is the weight and how is it packaged for international shipping?
A: The net weight of this crankshaft is approximately 15 kg. For export, it is first wrapped in a protective oil paper or plastic bag, then placed in a sturdy inner box, and finally packed in a heavy-duty carton with foam padding. This multi-layer packaging protects the precision-ground journals from damage during transit.
