[QUOTE="thetool, post: 23622, member: 1534"] I'll tell you how I remove it-but I'm always better when I can see it.....=). Raise and lock the boom. Lift the cab. Have caps and plugs available, or drain the tank. Have the area around the valve clean. Remove the panel with the steering levers. You need to mark and remove the bolts hoolding the linkage bars together, then remove all the bolts holding the panel to the frame. Remove the throttle lever and red knob for the manual boom lowering valve. If it's a G-series, remove the fuse box cover. Unplug harness attached to levers and back-up alarm if you have it, and lift out the panel with the steering levers. It also helps to jack up the machine, remove the right side wheels and the cover between. Remove all the hoses and tubelines attached to the valve, unbolt the valve from the frame and lift it out. You may have to remove some fittings from the valve to get to all the hoses and tubes. You may not need to pull the valve if you only have spools leaking, they can be re-sealed without pulling the valve, get back if you need more info on that. When you put it back in, leave the valve mounting bolts loose until you can start and/or tighten the steel tubelines, or you will be cursing. You're going to be cursing anyway.....=). There are a lot of connections, don't forget to mark any that you may have trouble remembering when you go bavck together. You never know what comes up between pulling it and putting it back in, and memory often fails. A woring hook-up can cost big time trying to get it figured out. There's more to it than that, but that's the basic idea. If you have foot pedals, you have to undo linkage. If you have hand controls, you have to remove actuators, but all that you'll see when you get the boom and cab up and get the steering panel out. Don't even try it without raising and locking the boom. If your valve is inoperative, there are ways to get it up with a hoist or another machine. Good Luck and keep us informed......=). [/QUOTE]
