How to identify your engine - engine numbers

Engine number position on most models

Engine number position on '05 series models
Current engines details on can be found on a foil sticker on the rocker cover.
When a customer contacts us for parts we invariably need to know the model and serial number to identify the particular application from the vast range of engine models that have been produced over the years.
Kubota have Produced engines in configurations from single cylinder to six cylinders. Kubota identify their engines by a very simple system: single-cylinder engine numbers commence with 'O', 2 cylinder engines with a 'Z', 3 cylinder with a 'D', 4 cylinder with a 'V', 5 cylinder 'F' and 6 with 'S'. Following this letter there is a 3 or 4 digit number (eg Z 482) then a space followed by the engine serial number.
On most Kubota engines the model identification and serial number can be found on the machined flat face adjacent to the fuel injection pump (see right).
On 05 series engines the identification details are also stamped on the rear of the cylinder block cylinder head joint face. It will more than certainly be necessary in most cases to scrape a heavy deposit of paint off ) perhaps several coats thick) to reveal the details.

Identifying the D1105 & V1505
There are two distinct types of these 3- and 4-cylinder short motors which are not interchangeable, so must be identified before you place your order with us. The difference is in the timing gear as shown here.


Looking to the front of the timing gear -
'Type A' has FIVE gears 'Type B" has SIX gears


Looking to the rear of the timing gear -
'Type A' has THREE holes 'Type B" has FOUR holes
