Hi guys,
I need help with some issues iam having with my 1997 CAT 950F II loader, first off i cannot stop the engine after i have finished working with the machine by simply turning the ignition key to the off position! instead i have to either raise the boom to the max or lower it to the ground and keep pushing on the raise/lower lever! this issue started few days after i removed and rebuilt the engine, before that it would crank and shut off normally using the ignition key.
The second issue happens when i raise the boom for the first time after i start the machine, once i let the lift lever go the boom instantly drops about a foot and then it holds position, also when i fully raise the boom with an empty bucket and shut the engine off, it would start dropping down slowly without noise til it hits the ground but it happens within 8-10 hours, and in both cases they happen regardless if the machine is cold or warm.
The third and last issue is that this machine was used to load Sulfur prior to me purchasing it, and so the frame is covered with an inch thick of Sulfur, as well as all the wires and cables/electrical connections are covered with this stuff, which caused lots of rust on the lower cab area and cab filters access doors, and I've had to replace many bad wires due to this issue, my question is what's the best way to clean this stuff off? needless to say that i had few sore eyes nights and went through few types of goggles until i finally realized it's not gonna happen the easy way.. any eyes-saving tips ppl :bash

Thanks in advance for this great Place.
