Ark 550 loader on a John Deere LA

Recommended Posts

Exlr82fast

I bought a 1941 John Deere LA that has a Ark 550 loader that someone has put on it. I was told the loader was off of a WH D250 there is some red paint here and there.  I fell in love with it as soon as I seen it. I've never jumped on the team GREEN band wagon. But here we are.  I hope even though it is not red you guys might still help me out. I'm in the process or rebuilding the cylinders the seals were shot. I have read that it's a good idea to put a filter on the system. So was curious if anyone has done this? Also to trouble shoot I hear of people saying to put a gauge on it and so forth. What sorta pressure or psi will this system produce? Gauges range from 0-100psi 0-300psi ect. So what is appropriate? The pump pulley is slipping but I think I can engineer a better bracket to tighten the belt but I'm a little worried it may be going out but I have my fingers crossed. I may have more questions as I dig into this any help would be great.

:text-welcomeconfetti:That,s a neat setup, even if it is green.

John Deere copy rights there manuals, so they are hard to find free online.  They are for sale online, that would be a good place to start if you don't have one.

I'm not familiar with an LA model, but a John Deere B All Fuel Model has 70 PSI and Gas Model has 110 PSI compression.

This set up is using the hydro pump that came with the loader I assume. The LA doesn't have any hydraulics of it's own. I wish it did I'm a bit concerned that the WH D250 had 20hp rpm of 3600 is a bit different from the JD LA 14hp 1800rpm.

I think he”s talking hydraulic pressure for the pump?

How I put one on my D200.  Could have been simpler plumbing but I used what I had lying around.  Filter set up came from Northern Tool

:WRS: Really nice looking LA!! You even have the hard to find lower nose piece on the front.:handgestures-thumbupright: A lot of the lower nose pieces are missing from the LA's. It had to be removed in order to attach some implements and was often times never put on again.

I don't have any Green in my barn, but if I did it would be a LA for sure.               :text-coolphotos:

As of now I have the hood off...and i made a new adjustable bracket to tighten the pump. The old one had the bracket welded to the same piece that the pump was mounted. So if I begged down it would flex the unit as a whole and the belt would slip. I think I will have it right now. I'll post pics when I get it all mounted up. Thanks for the replies guys I'm really proud of this machine.

They are cool little tractors, even if they are green & yellow :ychain::D. Just wondering if by chance the serial number tag is still there? It was a brass tag that was riveted about center on the rear axle. This were prone to getting knocked off, most times all you will find is the rivet holes.

 

I will have to see if I can find a picture of my dad's LA to share with you.

It dose have the tag I cant remember what the numbers are but it is there. I'd like to see it. I live in Broadway Va there are 2 good sized tractor shows here and several parades around. I've only seen one that I know of little rare in these parts.

Love pre-1960 Green and Yellow!  I don't care what you guys say, about  JDs, the sound of that 2 cylinder working  hard brings tears to my eyes and that hand clutch!  WELL! what can I say? Both my grandpas and my uncles had  model "A" when I was growing up. Care to guess what I was driving back then?

Here's a couple shots of what I did to the pulley. First pic is what it came with. Was a piece of 3/8s all thread going threw a bracket that was welded to the bracket that holds the pump. Under load the whole thing would rock to where it slipped the belt. Second was what I made. I made the assembly so I can take it apart easier and it is attached to the fan pulley bolt. No more slipping that's for sure.20190515_160528.jpg.2e458cab92cd0fb1416dfeee1817d982.jpg20190519_194602.jpg.70dba49eafcfb6ed38dde6d9f0441dc0.jpg

That looks a little tiny bit more robust!  :handgestures-thumbupright:
