just bought a yardman 998 tractor with a kwik way loader. pto on tractor seems to be working but no power in the loader. won't move. Can someone tell me how to test to see if its the pump or any other suggestions? No leaks found and fluid level is good.

Thanks

I would check and make sure the shaft is spinning on the pump. If it is then next thing I would do is a pressure test on the output side of the pump. Is there an oil filter on the loader?

I'm not familiar with Kwik Way. However, hydraulics are hydraulics no matter what.

Oil comes from the tank to the pump to the control valves to the cylinders which picks up the load.

Make sure the key that drives the pump isn't sheared. I'm assuming there is one.

You can tee in a gauge onto a pressure line to see if you are getting pressure out of the pump.

Is there a filter on the tank line, "suction line", feeding the pump? Could that be clogged?

If you take a line loose at a cylinder, does any oil come out?

Are your control valves 1 lever you control (pilot "joystick" style) or two levers you work back and forth (forklift style)

Does it have a pump, or is it plumbed to the tractor's hydro? Kwikway offered them both ways, sometimes, both ways for the same model tractor. For example, on the Legacy's, you can tap into the Sunstrand, or to the pump provided with the loader. Take a look at your lines and make sure they are hooked up one way or the other. No telling what a PO may have detached.

Thanks guys. Don't see a filter on the lines. Front pto spins and the chain coupler spins connecting to the pump. Where can I get something to test the pressure coming out of the pump. Where can i find out what thepressure should be.

Not sure about Kwik-Way, but some I've worked with had a filter built into one of the upright tubes/braces near the bottom where the hose couples up. If it sat and was dirty could be plugged there.

Don't see anything on the upright post either. Will check it out when I pull the pump and look for the key. Hope it's a simple fix as it is cold as heck her in Michigan. it would be nice to use the loader on the snow. Has a 3 point and a grader blade on the back but can't do much with a dead loader dragging around on the front of the tractor. I do appreciate all the help and will keep you guys updated.

The relief valve would of been set at 1500 psi from the factory. If you get a gauge to test the pressure, make sure you get one rated to handle at least 2200 psi, or the gauge will become the relief port.

The filter should be on the bottom of the loader upright support, in front of your legs, opposite of the one that has the loader control valves.

Welcome to GTTalk , tuff question without being there , at least for me lol , I would try the easiest thing that you can check on that tractor without doing a lot of work if possible . Maybe follow the output line of the pump to make sure someone didn't install some type of spliter ( I used one to switch from my fel to backhoe on my Ford ) , it might be a different lift for your grader blade idk without seeing it

If you check pressure, make sure gauge is on a 'T' in line and not just connected to output line, that will blow out the pump seals.

Just thought of this , if the loader pump is seperate from the working rear lift and the tractor is outside, it could have gotten moisture in the hyd system and froze

Ok guys it's working. Pto connects to the pump and two bolts gulf the two shafts together instead of a key. Bolts had warn down to the point where the pto would spin ant the pump would turn slow and loose but not enough to do anything. Thanks for your help. I will post pics once I put the front end of the tractor back together
