I was just thinking about that..... Dan

Hungry little buggers 😀 Didnt even wait for it to cool down. Think I have the temps for the new oven figured out but may need a few more tests to be sure..... Dan

You are making something simple complicated. Bucket raises and lowers tells you NOTHING about whats happening at the motor. Take the hoses off the motor and operate the controls to rotate the motor both directions. You should get oil flow from exactly one hose in one direction and the other...

First of all I was thinking electrical cintrol not mechanical. Are you using a third function valve? I looked at the Parts diagram and rotation is by a hydraulic motor. If you are using the bucket spool with a diverter you will get pressure on BOTH hoses and the motor will only rotate in one...

How can you have flow and no movement? Dan

Pop the hoses off the cylinder and see if youvare getting flow. My guess is the diverter is not diverting..... Dan

I think uou need to run a few diagnostics before you start throwing parts. Based on the problem description I would be wondering about the port relief valves on the boom.... Dan

You are going to like your new lathe. Grizzly, PM, Birmingham, etc are all rebadged asian imports. The actual manufacturer varies by model and importer. Dan

OK - found it. Loader Control System (LCS) ERGODRIVE Loader control valve by ALO. Thats a sophisticated device and above my pay grade. You might want to purchase and read this: https://www.ebay.com/itm/364996070411 Dan

What sort of "issues" are you having with the control valve? Thats essential information for determinijg how and where to test it. I dont know what "open lcs " means. . Case and Massey often have closed center load sensing (CCLS) hydraulic systems. Can you provide a link to the parts diagrams...

Not that paricular valve but many of their other models. The hydraulic pump on your tractor produces 8.7 GPM max. OOPS - I see that hoe has a dedicated pump - either Cessna or Fenner. If the pump has a dataplate with model number we can lookup the size. Dan .

Get a circuit diagram, a test light/DVM and trace the power circuit. Usually pretty easy to find the point where power disappears. Dan

Adjust the feedback rod NIWM illustrated. With engine running raise hitch to top. Loosen lock screw on the rod and adjust length until squeal stops. Dan

Factory remotrs are certainly the best integrated. Looks like two OEM valves cost ~$1500. A third party kit will be as much if not more and if you roll your own from scratch you might save $700. Neither will be nearly as well integrated and many wind up being ugly warts. You are going to have...

Skinny fingers but stupid small and twitchy mobil keyboard. Add in auto-complete and auto-correct and you get symptoms of a stroke :devilish: Dan

I dint know much about your tractor but you fill through the opening with the cap. It sounds like the squeal may be the pressure relief valve in the hydraulic system. We can work on that. Dan

Correct the oil level but your "squeal" is probably unrelated. Dan

No stroke 😀

Put a drain pan under the loader hydrsaulic putlet block and trmove ths hose connected to the pump port . Set engine speed to idle, start the tractor, and you should immediately get a stream of oil out of the block. Shut the tractor off to prevent pumping the tractor dry. Of no oil the pump is...
