Al, the belt tensioner bags should hold air. If they're not there's a pressure regulator mounted behind the engine start panel in the engine compartment. The maintenance manual recommends rebuilding the regulator every two years. Few do this. If you choose not to then the usual operator behavior is to let the engine idle until you see 60 psi on the dash gauges, at which point the tensioners should be inflated and you can then press the fast idle button. They are part of the accessory system so pressurizing your accessory tank should inflate the tensioner. Remember your air hose color coding: Red: Secondary Green: Primary and Delivery Yellow: Parking Brake Blue: Suspension Black: Accessory Brown: Trailer Brake RE: Thomase On Board Air - cubeman - 02-21-2019 11:07 So your saying those springs are filled by the engine or compressor and when you shut down there is a regulator that should hold the air. Again this depends on the regulator and air springs holding air . RE: Thomase On Board Air - travelite - 02-21-2019 11:15 Al, there's a check valve there too. RE: Thomase On Board Air - cubeman - 02-21-2019 19:38 sounds like a plan . |
