I have a d4h lgp that has some roller frame problems and needs new bushings on the dead axles, possibly line boring also. Is there a way to adjust the roller franes if we don't get the machine work perfect? I've been having problems for some time with tracks wanting to come off and am starting to wonder if there is also an alignment problem
Look at track frame pivot and see if has slop. Equalizer beam badly worn on my machine also.
