Just behind the lift handle is a small plate held on with 2 1/2" headed bolts,you may or may not have a dump valve knob sticking out from here,if you do check that it has not been left up.Unscrew and remove the valve,remove the plate,under it are 2 plugs with screw driver slots in,or just one and a hole where the dump valve came out of.The plug on the right is the by-pass valve,unscrew it ,there is a spring behind it,remove the spring,you will now see a hollow plunger,pull this out,it may be stuck,if it is whittle a piece of wood down till it almost fits,knock it in,and pull out the valve.Unscrew the plug inside it,clean the orifice plate and nylon screen and plunger,the plunger should slide nicly in and out of the bore.
On the left is the hold valve,remove that,remove the retainer and very small ball,clean all the parts. While the valves are out,set the stop control to stop so the engine will not start,crank the engine for a few seconds,and allow the oil to flush out any dirt,replace the valves and check the system operation. The I&T manual covers all of this. Good luck.Dont forget change the paper element and clean the gauze and magnetic filter underneath the tractor
