Hi all, if I may ask I have purchased a D31-16 s/n 25645 in Australia, seems like a good machine. Can anyone help with a year of manufacture.

 

[John C.]

My sources don't track the overseas machines. What I do have shows serial numbers with no prefix starting in 1977 and ending in 1988.

 

[Aaron N]

Do you kmow the year for a D20P-6 SN:72005?

 

[John C.]

My sources only show up to Sn. 71300 which states it is a 1990 model.

If it's a D31A-16 it will be a 1977... If it's a D31P-16 then it's a 1978...

Hello everyone, I am trying to determine the year this Komatsu D21-A dozer is and engine make, this is stamped on the left rear by the final drive in a vertical orientation. The machine is power shift although this stamping is for a straight drive if I understand correctly. Thanks in advance.
Here is the tag from the valve cover on the engine. The valve cover has Komatsu on top.
. This tag is at the operator station entry

My serial number is 72157 and was told its a 1991 so my guess yours is a 1990 possibly a 1989 model

Sorry to hijack the thread but I need to know the year of my Komatsu D20A-7 dozer with serial number 77216. Hoping Darinray is still out there.
