Komatsu D-21A Need some advice ?

Post by dillon45 » Sun Apr 30, 2017 5:52 pm

Can't get no help on other forums. Maybe someone can help me here, this is the problem.
Komatsu D-21A I heard a bang on the left. Problem, I have no power to the left track, the right track is ok.
Can anyone give me an idea as to what could have broke ? Everything else works as it should. I would really appreciate
some ideas as to what might have happened. Thank you all in advance, sorry to post on a JD forum but can't get no help anywhere else.
This is my neighbors dozer and I'm trying to help him with what ever info. I can obtain, thanks again.

Have you tried Heavy equipment Forums? In the dozer forum there is a subsection for Komatsu D20 and D21 dozers.

I would also suggest the Yesterday's Tractors bulletin board- they discuss a wide spectrum of heavy equipment.
(1) JD Straight 450 crawler dozer with manual outside blade; (2) JD 2010 diesel crawler loaders; (1) JD 2010 diesel dozer with hydraulic 6-way blade; (2) Model 50 backhoe attachments, misc. other construction equipment
