I have a series 1 D-17 Allis and I have a loader on it. Pressure from my transport valve goes to a 4way spool that reduces the pressure for low pressure implements. It will run my loader but I do not have enough pressure to pick up over 800 lbs. When the 4way spools hits a certain pressure it will open up and bypass to the reservoir. I shimmed the spring but didn't help. What can I do to increase the hydraulic pressure to my loader. When pressure comes out of the transport valve it is single acting. When it goes through the 4way spool it changes to double acting. My loader is double acting.
