0 Freightrain Posted May 23, 2019 Share Posted May 23, 2019 Yup, when I had my original 673 pump rebuilt they told me that was included. Quote Larry 1959 B61 Liv'n Large......................

0 Freightrain Posted May 22, 2019 Share Posted May 22, 2019 So, removing the governor line from the compressor does not make it build air? Has the coupler broken and the pump not turning? Remove the intake line, spin motor with starter and see if you feel any suction. Quote Larry 1959 B61 Liv'n Large......................

I just checked and there is no suction at all so I think I might have bad air compressor here thanks Quote Link to comment https://www.bigmacktrucks.com/topic/57324-air-not-building/#findComment-423398 Share on other sites More sharing options...

They are phonelic composition and if not renewed with the compressor change, are highly suspect.
