FAQ

Q1: Is this kit a direct replacement for the Kubota D905 engine without modifications?
Yes, this kit is designed as a direct OEM replacement. The pistons (16224-21110), rings (15901-21052), bearings, and gaskets match original Kubota specifications. No machining or modifications are required for installation on a standard D905 engine block.

Q2: Does the kit include all gaskets and seals for a full engine rebuild?
This kit includes the cylinder head gasket, but it is considered a partial overhaul kit. It does not include a full gasket set (e.g., valve cover gasket, oil pan gasket, front/rear crankshaft seals). We recommend purchasing a separate upper or lower gasket set for a complete seal replacement.

Q3: What is the recommended installation procedure for the piston rings?
When installing the piston rings, ensure the ring gaps are staggered at 120-degree intervals around the piston circumference. Do not align gaps with the piston pin bore. Lubricate the rings and cylinder bore with clean engine oil before assembly. The top compression ring is typically marked with a dot or “TOP” – install this facing upwards.
