IH-1000 loader update/ new question

First of all thanks to all that helped me figure out the pump heating up problem. Anyone new this is a Farmall Super A with an IH-1000 loader.

ok back to the loader, the tractor's HYD pump doesn't get hot now that we un-plugged the orphice. The problem we are having now is the tractor will not lift much. Is there some adjustments to get it to lift more weight? I am talking it will only lift 200-300 pounds maybe a few feet off the ground and quits lifting. Is the touch control the problem is could it be the spool for the loader?
any thoughts?

If it holds when up, under the load it will lift, it is probably the pump, or the relief valve spring too weak. Were it mine I check the relief by seeing if it lifts well very cold, then gets worse as it warms up. If it does that I would put in a heavier Hydraulic oil (ISO 46) might make it perk up. Running it hot may have taken its toll. Jim
 
There are adjusting screws on the loader on each spool valve that adjust the bypass pressure.

You should install a pressure gauge inline between the pump and the control valves on the loader. Run the loader up to the stop and observe the pressure on the gauge. It should be somewhere around 1150-1200 PSI. Adjust the pressure relief screws to achieve this pressure. Perform this procedure for the main loader arm valve and the bucket control valve.

Don't keep the valve open against the stop, but just hit it momentarily to view the pressure and then let off.

There is a link to the manual on farmallcub.com in the manuals section. I guess I can't post a link to the manual on here.

All of the info you should need is in there.
