Cross Compatibility & Important Notes
D1105 vs D1105-T Are Different Engines
The naturally aspirated D1105 produces 18.5 kW while the turbocharged D1105-T produces 24.5 kW with different internal components and injection settings.
Suffix Determines Fuel System Type
EF02, EF09, ET03, E3B, B, BE, K and CR-T variants indicate different emission and control systems. Early builds use mechanical pumps while D1105-K features electronic control for EPA Tier 4 compliance.
Cylinder Count Identification
Kubota model codes begin with cylinder count: Z for two cylinders, D for three cylinders, V for four cylinders. These are distinct engine families with different specifications.
