single action cylinder with a 606

JAsher452x · May 17, 2015

at an auction this weekend i picked up a wagon and a gear with hoists on them. they need some work but i was wondering is there any way to use the my 606 with these single action cylinders on the hoists or will i need to convert them to dual action cylinders?

You can use it with single action cylinders. If you want a slow controlled drop you will move lever only part way and this will put the system on high pressure but that is not a big deal breaker. For a fast drop, just put valve in float and let it go down. We used to hook single action cylinders on that style hydraulic valve, like on a tail wheel on a plow, so that we raised the cylinder by moving lever forward which would normally be the lowering position. Then when we lowered the plow, we pushed lever all the way forward into float and left it there. When raising at end of field, pulled lever back to again to what would be the normally lowering position. Doing it this way worked out really good with less total lever movement.

thanks for the info Pete, but what i am confused about is float? my two valves do not have a float position. both valves on my 606 are currently hooked up to my 2000 loader. the inner valve is a detented valve hooked the the load sense check valve and hooked to the lift cylinders on the loader. the out board valve is a non-detent valve hooked to my tilt cylinders, before it is plumbed to the loader, it is plumbed into a diverter valve on the rear so i have a set of remotes to use if needed with out having to unhook the loader.

So if i am understanding what you are saying is to to hook up the one line for lift but when i lower hold the valve and and allow the pressure relief valve to open which will allow the down pressure to go through the relief, and the lift to return to tank through the valve?

I have not seen any factory valves of that style that do not have a float. I looked in parts manual and it shows the same detent sleeve in a 606 , on both 1 inch and 7/8th in spool valve that is used on 66 series tractors. That sleeve is what determines if you have a float or not. Tractors do have float lockout's but they are on the outside and just block total movement of the spool and easily moved off to the side.

A two way cylinder while being operated has pressure on one hose and return on the other. It how they work,you pull the lever up and the valve puts pressure on hose A and return on Hose B... the cylinder extends. Now you push the lever down and the valve puts pressure on hose B and return on hose A... the cylinder retracts.

When you hook up your one way wagon hoist cylinder to the 2 way valve and pull up on the lever the valve puts pressure on hose A and return to Port B (which does absolutely nothing in this case) But the vent on the cylinder allows the air out of the backside of the cylinder. The cylinder extends and the hoist raises. Now push down on the lever and the valve puts pressure on port B (which does nothing but bleed off the pressure through the relief valve) and port A goes to return. The oil from the cylinder is pushed back in by the weight on the cylinder. Air enters through the vent on the cylinder to allow the piston to go back in.

Basically hook up your 1 hose and use your wagon

thanks for the insight. i just wanted to make sure it would work or not. I know that i have to replace the cylinders on both wagons, and single action with save me a few dollars. only paid $25 for the pair of wagons.
