Anyone know what causes a track to favor the inside of the squirrel cage? I took the tracks off and checked for alignment of the cage and motor and it looks great (started the machine and spun the cages around with the motors...checked for wobble too). It's chewing up the inside corners of the lugs. Same machine seems to have weak motors (doesn't want to turn on pavement...top speed is only around 5 mph), so I pulled tracks and wheels to check for issues....found none. Am trying to get a hold of a pressure tester for the pilot block to see if the pump is up to snuff. Service manual doesn't give me a pressure reading. Anyone know what it might be? I know the auxilary should be in the 3000 psi range. Do the motors tend to just quit or do they die slowly?
