I am in need of a shop manual for a Komatsu D20-6A. I have a Service Manual, doesn't help. I am about to tackle steering clutch / brake problems. Any suggestions?
 
Right track will not move while running. Towed home in neutral. Was pulling to the right last time I ran it. Seems like brakes were at the end of adjustment. I really need a manual to tell me how to tear it apart so I don't mess something up!
 
Before you tear anything down the first rule is to establish what's wrong,having no drive to the right track could be several things,the final drive could have stripped a gear,the steering clutch could be adjusted too tight,the clutch could be slipping or the cross shaft broken,I would remove the drain plugs from the clutch compartments and see what is in there,drain the final drive and check the oil for metal,check the clutch adjustment,if all that checks it look like you will be removing the offending clutch,diesel tank off,disconnected linkage,cover over clutch off,brake band out,bolts removed from both the clutch drum and hub,lift out the clutch,you will have to improvise and make a tool up to compress the clutch springs to get the clutch apart,you need the manual.
