Dozer track problem

[professor]

I have a Mitsubishi BD2F dozer with pyramid track pads. I put new chain,rollers and sprockets on the machine however the left track chain rolls up on the front roller and slips off. /forums/images/graemlins/confused.gif What is the problem and remedy? Thank you for the help.

Heres a site that maybe someone has experience on a Mitsubishi. It sounds like the front roller is out of alignment and you will need to reposition the shims or add-subtract some to bring it back in line. I have no experience with the Mitsubishi, so I cannot advise you on the correct procedure. I would strongly advise you to get a repair manual so you are not working blind. Good luck!
