C160 Loader Project

[Dieselcowboy 210]

Axle is from a plain old 210 JD. I did weld a longer arm on where the tie rod attaches. Matches the w.h. length. Like having power steering. It's just a hair wider than the rear wheels. In person looks kinda bad a#*.

I hardly run the engine on this thing very hard. Only enough for what I need. So hopefully a smaller pulley will make up for the lack of R's. If not I'll set back and tell myself I should have listen to those guys.

This is my first Hydro W.H. and I am scared to death that it won't last / hold up anyway. Always had 4/8 speeds.

You will need to run that engine at near to max rpms, the engine is designed to run there for adequate cooling and the transmission fan is designed to run at those revs as well.

Are all of the John Deere 210's front axles forward swept axles?

[Dieselcowboy 210]

The JD axle is really swept back on the Deere but swap the spindles left for right and now it can be swept forward. I understand the cooling thing as I keep of around 75 commercial zero turns running where I work. We mow 1800 acres of grass weekly there.

For those interested in the JD axle swap there are a few pictures on here:

A few of us have done it (mine's not finished yet), and Kevin (Kpinnc) has one on a 518.

once again really good info here

Finally an update and pics to come. Made it into NAPA with the tractor and made the hoses custom to the machine. Works really well except I did not listen to some of you and got too small of a pulley on the pump. No problem ,easy fix. The pump chattered a lot when I tried to use the loader. I idled the engine way down and the pump got quiet and the loader just worked perfectly and quick. Almost killed the engine though. Try to get some pics of hose routing and locations in a day or two.

cool stuff, what a great filling when the time you spend on something works out.

Need Help ! Pump is still chattering with a 5in pulley on it. Works really good with engine at low idle. More throttle and more chatter /slower hyd. Any ideas? Maybe someone has experienced this before.

I experienced something similar with my FEL pump.  Turns out that I did not have one of the quick connects seated all the way, and it wouldn't allow flow.  The pump chattered like crazy.  Might be that you have restricted flow in the system?  Just throwing out ideas.

Keep us posted, I'd like to know how you resolved it.

BTW, what kind of pump are you using?

[Dieselcowboy 210]

Useing a webster pump I had laying around. May have to switch to something else?  I'll Let you guys know what comes about.

I think you are going to have to do some research to see what the optimal RPM's are for that particular pump.  Mine has a Cessna pump which I believe are the most common type used on the Ark loaders.

Also, given that it 'works really good' even at the low RPM leads me to think that you may be overpressuring the system at the higher RPM's and/or you have a flow restriction that is causing high back pressure.

[Dieselcowboy 210]

I may have a return restriction. The return hole on the back of the tank is very small. It is the factory hole for this but with the experience in hyd I don't think it is really big enough. May need to drill a hole at the top of the tank and put in a bigger return hose. A smaller return hose can really slow things down correct?

Before you start drilling, it might be worth asking; what exactly causes the pump chatter?  It has been my experience that an incorrectly coupled quick connect caused it.  It is not necessarily the case here.  There may be (probably are) other things that cause pump chatter:

 

Flow restriction (clogged filter if you have one?)

Not enough feed to the pump

Not enough back pressure

Bad pump

 

As always, start with the simplest things first. 

BTW, any chance you can T in a pressure gage somewhere?  Putting it in right after the pump will tell you right away if you are overpressuring the system.

These problems can be tough but one thing would be to isolate the pump from the system an run the pump. Use a gallon jug that you can run into and out of with the hoses on the pump and see if the chatter goes away. Gear pumps are positive displacement and will slip the belt if they are not happy. The hydraulic fluid is another place to look too. Just some thought.
