I just got an 800 case ih planter and cant build but about 3 pounds of air psi. I know I need 8-9 psi but she won't do it. 540 pto, bands on 4 rows of the drum not being used. New filter on return line. also the drum doesn't turn smoothly some times it stops then re starts again. Please help as this is getting to be not so good of trade.

Check supply hose to the P.T.O. pump for signs of collapsing while the pump is running.

look for air leaks.. have had failed rivets where ther fiberglass hoppertop fastens to the steel on your seed hopper... have used sickle section bolts in place of rivets to repair ..aslo is your lid fastened down with all 4 clips? very important..ended replacing hopper top on my 900 couple yrs ago
#1 check gasket on Lid!
#2 check gasket on Drum!
These 2 items will wither make or break your air volume.
Put graphite around the drum gasket. Check all grease bushing and drive shafts, the drum is driven off of the gauge wheels it should turn smoothy. It it is jerking there is a reason!
Make sure the 2 guage wheels are the same, Make, Size, Pressure, EQUAL in all respects, Check drive chains!!
The PTO runs the pump, the gauge wheels run the drum, 2 different systems and drive sources.
If the gaskets, and seals are good then the pump us the problem or possibly the oil level.
If the drum is jerking, odd tire, size, pressures. Or dry bearings, bent shafts, Drive chains have sticky spots!!!! it doesn't flow around the sprockets uniformly!!!!! This can be easily over looked!! Hope this helps!

I have had to replace a faulty guage several times. Could be the air problem.

Last year the pto pump on my 800 gave up, it was a slow death. Pressure just dwindeled away.

This planter has to be getting some age, if the other posts advice dont help check with soapy water on tank lid, firewall seal, hopper half seams for air leaks, it will cause bubbles, also the fan impeller shaft has 2 sealed bearings that may be dry or lube poorly, replace them. They started making them about early 80s, the 900 series came out in 1987. If the airleaks show up reseal with tube silicone. Also check the speed of IPTO, clutch discs in pto on IH tractors will trip you up also. Good luck

Jerky drum action is probably the clutch being worn. We replace ours every 2-3 years.
