realwolfdaddy Posted May 6, 2013 Share Posted May 6, 2013 Little off topic but i know ya'll can help. I have a Galion 118b with a 4-71 that hasn't ran in 7 years. I attempted to start it after all these years. bled the system, started it with rack stuck, removed the injectors loosen the racks, now it runs idles but only using the lever on the governor, but the input via throttle pedal or hand doesn't have an effect on rpms. I knows this sounds crazy me asking but the machine has been vandalized and all the gauges broken so the crazy part i haven't checked the oil pressure yet, I will replace next time I start it. The question does the throttle input require a certain amount of oil pressure to operate rpms? and how scarey is working on a detroit governor?

41chevy Posted May 7, 2013 Share Posted May 7, 2013 I would think if the throttle works from the governor than the problem would be between the linkage from the governor to the foot / hand throttle. I don't recall a limited throttle through the oil pressure switch.
