Chappyjersey Posted March 20 Share Posted March 20 When lowering the bed on a Mack granite gu713 2016 the bed drops hard even when empty, worse if still loaded Quote Link to comment https://www.bigmacktrucks.com/topic/75305-bed-drops-hard/ Share on other sites More sharing options...
Joey Mack Posted March 20 Share Posted March 20 Are you able to slow it down by backing off on the lever ? Quote Link to comment https://www.bigmacktrucks.com/topic/75305-bed-drops-hard/#findComment-571676 Share on other sites More sharing options...

Joseph Cummings Posted yesterday at 02:39 PM Share Posted yesterday at 02:39 PM I'm guessing air controlled. Is the pump a Commercial Shearing C102D or a clone of it? I'm thinking it's a problem with your air control valve. You need to connect a gauge to the control and see if the pressure goes up and down smoothly Quote Link to comment https://www.bigmacktrucks.com/topic/75305-bed-drops-hard/#findComment-572719 Share on other sites More sharing options...
66dc75 Posted 17 hours ago Share Posted 17 hours ago The air control is supposed to be able to feather the body down but that's a fairy tale. I put a one way restriction valve at the pump. Full flow going up and adjustable flow going down. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75305-bed-drops-hard/#findComment-572780 Share on other sites More sharing options...
