Well I'll tell you a story that skytrack mechanics might not believe. I spent 24 hours working on a 8042 this summer. I wont go into all the gory details but every time the boom went above 40% then came back down it would lock up, slow to extend, no steer, all the functions affected. The only way to fix it was to shut the engine off and restart. After many hours, flow meters, and pressure gages installed I found the problem in the rear axle stabilizer cyl. I completely disassembled it and couldn't see a thing wrong. Since the machine was on a demo and we wanted to look good we air freighted a new cyl in and I installed it, problem never returned. I'm still not sure what was wrong in that cyl. but it was not an electrical problem, it was a lock up off hyd pressure in the valve block on the cyl. I know this because disconnecting the wires from the coils didn't fix it, you had to shut the engine off to relieve the pressure. Then restart and everything would be fine. If you put your ear close to the cyl you could hear oil whistling thru it. Unfortenently for you that cyl ain't cheap, upwards of 2000$ I think and I'm not sure what components to tell you to change because I couldn't find anything wrong with mine. If any other track mechs ever heard of this they can dive in. If they don't believe that a problem in the stab cyl could cause a problem in the rest of the machine they can dive in and tell me i'm crazy that's ok to. If you have no locale dealer that you can work with we are a dealer. wes
