Re: Smog Pump???

an alternator, a steering pump, water pump, then a thing that looks like an air compressor--with piping leadding to your first air tank. is it diesel or gas? crawl under and trace the lines (pipes). no one around here has ever talked about a smog pump, so i assume it's the air compressor. needless to say, don't remove it until you know what it is.

Re: Smog Pump???

Do you have catalytic converters? If so then there is a possibility that it is an air pump. Look for an A.I.R. port somewhere on the injection. A simple test would be to remove that belt and start it up with the tanks at 0 psi. If the pressure climbs you'll have your answer.

Re: Smog Pump???

gas bus with air brakes..has to have a compressor somewhere, typically it would be a bendix 2 cylinder compressor with coolant lines to the head and cylinders, belt driven with either a single 3/4 belt or a pair of 1/2" belts.
If you want me to take a look send me a pm, I'm at Sibley between 75 & Telegraph.
