    we bought a D20A komatsu, but we do not know what series it is. the serial number tag is hard to read because it has been sand blasted but the best i can tell the number is 15837. the strange thing about it doesn't have lever or joy stick steering, it is on 2 pedals the have a common center, it makes kind of an "s" between them but you can still hit both pedals with 1 foot. other than that, it is identical to the one below.

    what do ya'll think it is?
    thanks

    Nothing in my serial number book that goes that low. :( You shoudl be able to read the serial number on the very back part of the body on the left side by the final drive. It will be perpendicular to the ground. Let me know and I'll run the serial number for you.

    Good deal. The serial number states it is a 1979. Hope this helps and enjoy it. Take care. Darin

    thanks darin, also have questioned the local dealer and awaiting his reply also. Don't know if this would help but the M/N and S/N infor were taken from data plate that was actually attached to the blade. The M/N was DDR 031 2D, don't know if having this would better pin point the year, but again, my thanks for your time.

    hey Darin, would you have a line on where to purchase/find service/maintenance/parts manuals for the Komatsu D31E? Also, while doing some research on same, I often see a dash number after D31E-??. Can you tell me what reference this dash number is? It seems to make a difference in what manuals.

    Hey cropduster,

    With a 40000 s/n this should be a D31E-18. I have a copy of the service manual that you can download, no parts manual at the moment. The link below takes about 10 minutes to download over DSL.

    http://www.megaupload.com/?d=735TXE8W

    If I find a parts manual I will let you know.

    No prob cropduster, hope it helps. You can use www.komatsupartsbook.com for parts in the meantime, just choose the D31P-18 dozer, most parts should be the same. I believe the main difference in the D31E and D31P is that the D31P has a longer roller frame, the roller frame is mounted farther back on the case.

    Think E's are standard width pads, probably 18" and P's are wide tracks probably 24". On D39's that is the way it works ,anyway.
