Are the handles of both valves close to the QD fittings (left front of vehicle) aligned with the fittings/hoses?Question about the front loader. I finally got the truck running and the front bucket will curl up and down perfectly. Although, the boom on the front loader will not come up. I checked the travel lock pins to make sure they were not locking anything in place. I previously greased all the zerk fittings. I checked the level of hydraulic oil in both tanks and it appears to be fine. I’m still not able to raise the boom on the front loader. Am I missing something?
Both of those valves are open. Parallel to hoses.Are the handles of both valves close to the QD fittings (left front of vehicle) aligned with the fittings/hoses?
There is a safety relief valve on the cross member close to the hood. It connects the hard lines for raising and lowering. If that is stuck open, you will not get pressure on the loader cylinders. The rubber hoses will move slightly if you are building pressure against the pistons of the loader cylinders.Both of those valves are open. Parallel to hoses.
It's working now. I had to move the boom up and down 1 inch at a time for about 20 minutes to loosen it up.There is a safety relief valve on the cross member close to the hood.

If the loader cylinders are stuck you will hear a hissing/squealing sound from the pressure limiting vale behind the cab when you move the Up-Down lever.
Or to get the air out of the system, maybe?It's working now. I had to move the boom up and down 1 inch at a time for about 20 minutes to loosen it up.
It had a big arrow painted on the side showing one way fluid transfer. The hydraulics shop guy took the valve apart and compared it to several different types of Parker valves, which is what this is. He showed me the shuttle valve and how it was not the correct one. It was designed to only allow fluid to go thru one way, and not both ways as required for the loader arms to go both up and down. He said it was a completely different model than what was listed in the TM.If it was installed backwards, which it sounds like, did you try turning the check valve around?
