Mackdaddy2030 Posted November 21, 2014 Share Posted November 21, 2014 I use the Johnny Bar especially when I'm in the paver. I like on my '98 that I can set it at 10-15PSI and it will hold. I recently bought a '12 CHU and the Johnny Bar dose not stay in position. It has that stupid safety on it.Does anyone know of a way to make it so it will stay at the desired PSI?

6368 Posted December 6, 2014 Share Posted December 6, 2014 Johnny bar? Never heard of that one before. must be a regional thing. around here( PA) we call it the trolley valve or the spike. now olde time dozers have a johnson bar to control the blade.

theakerstwo Posted December 6, 2014 Share Posted December 6, 2014 You will have to change to a older valve.I have done tried this for a dump trucker.I know of a few guys that wish they had the newer valve that would not stay in place. What I mean is they spent a lot of time and money for parts trying to fix the stop lights for staying on. but this was on a bobtail truck.

fifth wheel Posted December 8, 2014 Share Posted December 8, 2014 I only know it as a trolley valve. An older crawler equipped with a johnson bar is the additional lever in the transmission for forward and reverse, which gives you all gears in forward and reverse.FW Quote Link to comment https://www.bigmacktrucks.com/topic/37803-johnny-bar/#findComment-269569 Share on other sites More sharing options...
