FAQ

Q1: Is this crankshaft a direct fit for my Kubota D1803 engine?
A: Yes, the 1G790-23012 and 1G790-23010 are the standard OEM part numbers for the D1803 crankshaft. It is a direct replacement. We recommend checking your engine serial number to ensure the correct variant is selected.

Q2: What is the installation procedure for this crankshaft?
A: Installation should be performed by a qualified diesel mechanic. Standard procedure involves removing the oil pan, connecting rods, and main bearing caps. The new crankshaft must be lubricated during installation, and all bolts must be torqued to the manufacturer’s specifications. New main and rod bearings are highly recommended.

Q3: How should I maintain the crankshaft after installation?
A: After installation, the engine should be run at low RPMs to ensure proper oil circulation. Regular oil changes with the correct viscosity grade (typically 15W-40 for diesel engines) are crucial. Always use a high-quality oil filter to prevent contaminants from scoring the crankshaft journals.
