The tractor should be fine running right with out being connected ?

Just to be real clear - Until you get a loopback hose installed you can't start the tractor to drive it over near the plow.

If the tractor and plow are still close enough to re-attach the plow's disconnects back onto the tractor - then in that case the fluid would have a return path, and you could test the pump.

Don't start the engine without some sort of a loopback path for the fluid.

Great! Thanks for clearing that up! After I dropped the plow I did drive it around some. I didn't know

will be interesting to see what if anything you broke by doing this. Looking at your pump, I don't see where a key would go.. Hoye may have been able to answer this for you

No doubt there is a key there. Dollar to a donut says yours is sheared. HYDRAULIC PUMP: Yanmar Tractor Parts

The pump was dead headed so key will be sheared. If it isn't the pump probably copped it and may not pump properly.

Today I will take the pump back out and look for the key. I will take pics.

I see the key on that 1 winston.. Maybe the way he took the pic of the shaft

The other thing that is weird is that I do not see the o ring or the gasket from pump to motor.

I see the key on that pump as well but there is no slit on that nut for a key.
