TO30 HDY lift falls to ground

Forget the relief valve, everyone thinks about the relief valve and blames that...it may leak but it wont cause anything other than the lower links to leak down faster than usual. The Relief Valve is to the rear of the Pump and if as you say the leak is over the Pump then it isn't the the Relief Valve. Drop the level of the oil so you can see the Pump more easily and you may find the leak that way. It will be easier to drain some oil through the drain for the rear axle which is under the diff, being smaller you can control the flow more easily. as long as there is about 2"/3" in the Pump chamber it will work. Don't drop the Pump until you find the leak. If you email me at: fergusontractors(at)tiscali.co.uk
and I will send more info to you about looking for leaks, but do try dropping the oil first and then tell me at the same time what you find and I may be able to tell you more of what it is from the information you give me. When you say it wont lift when it gets hot is this with an implement on the linkage, do you have the correct grade of oil in there NOT hydraulic oil. Let me know what you find by email plz.....John
