    2009 Komatsu D39PX-21A E03

    Have a 2009 Komatsu D39PX-21A dozer throwing a E03 code. Only turns on after about 1-3 minutes of operating. Won’t turn on when it’s in park no matter how long it runs. Machine runs strong and doesn’t go into to limp or bog down.

    Komatsu dozers and hystat issues

    Do komatsus seem to have more hystat issues versus either brands? iv got a d5g and it a great little machine? the machine I’m looking at is a 39px said it I’m assuming is swapping fluid from a final to a hystat or something like that. is this a common issue? can it be fixed relatively easily...
