Mort Posted May 14, 2012 Share Posted May 14, 2012 On our old R600 we are having issues with the start tank not refilling properly. What valve am I looking for that controls this?

mowerman Posted May 14, 2012 Share Posted May 14, 2012 well theres generally only 3 valves on then... delivery valve,, start engine valve,,and tank fill line check valve,,,all 3 of them are pretty inexpensive,,if you have a leak,,,i would just start by changing all 3,,and new air lines...but if you dont wanna spend too much,,i would start by changing the inlet fill tank check valve,,try that first,,if that dont do it,go to engine start valve,,and listen for air leaking.oh,,also sometimes the factory installed a seperate shutoff valve to air tank control waqs on dashboard,,,from what i remember,,it was a big chrome toggle switch..good luck bob 1 Quote Link to comment https://www.bigmacktrucks.com/topic/25103-air-start-tank/#findComment-119358 Share on other sites More sharing options...
