No fluid Dirty filter or sheared keyway on the pump shaft Hoye # HWK 522 Shaft key. Very rare for a pump to go bad. That's what I would look for next is the Shaft Key. Keyway/Shaft keys good Then I bet the pump went out.

This thread has progressed rapidly today. Not for sure what I am looking at in your earlier pictures but want to think those quick connects are coming off a diverter block on your three point. If so I suspect you have deadheaded your pump. Was everything working before taking those quick connects apart?

Yes everything was working. I didn't even start the tractor. I got the whole plow system off. I had to jack the front of the tractor up to pull out everything. I started it up and it didn't work.

I sure hope it's a keyway that price looks way better than the price for the pump.

If you find a sheared key or worse and repair it then don't crank again until you complete the circuit at the diverter block or it will happen again.

The diverter block is what you pictured in post #9. The lines with the quick disconnects are coming out of it.

Before disconnecting the quick disconnects to your snowblower the fluid traveled out of the diverter block and through the snowblower system and back into the 3 point at the diverter block. That is the circuit. When you unplugged the quick connects the pump or fluid was dead headed. One solution is to fab up a loop hose with a quick disconnect on each end to match the ones on the diverter block . Plug the hose on and the fluid can complete the circuit.

I apologize for my lack of word usage. Not good at explaining things.

You should have a control valve of some sort on your snowblower. Any chance of a picture of it?

I don't want to be held accountable for any bad advice I am giving here. I certainly don't have enough info on your system to do much recommending. Just based on what I am seeing I think it is dangerously plumbed. :confused3:

Here's my (previous) YM186D with a return hose connecting Out to In on its diverter block. The hose replaces a loader or something that is no longer on the tractor. You can't pump fluid against a closed quick-connect, it has to go somewhere and this return hose is the best solution.
