Northern Illinois | If this thing is RTO or a RTX there is a insert valve on the back of the trans. that commonly gets plugged especially if you have all this air contamination issues with this truck. If all of us experts on here can't help you go to Roadranger.com, they have a very helpfull website. As far as your air issue of course drain you tanks on a regular basis. You air dryer should be serviced but before that take the air pressure line off the compressor. Take a stiff piece of cardboard and hold it near the fitting, start the truck and see how much oil is blowing out. Make sure the air tanks are empty so the gov. is calling for air. Bendix had a crazy test, you draw a 1" circle on the cardboard and hold it 2" away from the fitting and when you ran it, if the oil spatter did not go outside of the circle the compressor was considered good. Good Luck. | |
