Hi All. I have been trying to track down this issue with the 75xt for a few days now. I lost all controls to the bucket and boom. Its not a traditional interlock issue, i have a green status light, the bucket controls will move, and the machine will move forward and reverse. Just no response from the bucket. Ive made sure the aux pedal is centered, and took out the main relief valve on the loader control valve to inspect it. it was clean with no debris. When i lost the ability to lift and tilt the bucket, it was not under load at all. i parked the machine lifted the bucket about half way, then lowered it, and it would not come back up after that. any advice is much appreciated!
Is the hydraulic gear pump for the loader in the back? As in the parts lookup LINK . ( powertrain> pump, gear mounting) Might be the pump coupler
Thanks for the suggestion. By the time i found a 12 point 10MM socket (what the heck!?) and got the bolts out, a storm came through. Hopefully i can wrestle it out this week and report back.
Thanks ozarkag and alrman ~ the coupler was pretty rounded. New part is on order!
