Ford tractor leaking coolant (pics)

[maxamillion125]

I have a 1710 Ford with only 550 hrs on it and I noticed green coolant leaking out at a pretty good rate today. I ran it for about 3 hrs and hopefully caught the leak in time before it caused any other damage. Engine temp was normal. Anyway can you guys tell me what parts I need to replace? Is it just a seal? Thanks

i can't even see the leak. have you checked core plugs, block plugs/petcocks and bypass hoses/drains.

The fluid was spewing out of the connection just below the silver thing in the first pic. Exactly where the bottom of the silver thing connects to the thing below it. Sorry I don't know what either on of those parts are. You can see where it's still wet with green fluid.

i'm not familiar with your new tractor.. but the silver thing looks like a hyd pump to me.

i can't pull up the exploded diagrams from the NH parts site on my phone.. but I suggest you go there and pull up the engine exterior details and exploded diagram... see whats behind that area on the block.

that or wait till rickb wanders in and tells you.

he's the resident NH expert.

Looks like two leaks to me, the silver thing is the hydraulic pump, the blue thing under it is the valve feeding the power steering, looks like the o-rings are way past due for changing (see pic below)
If you're really seeing antifreeze, I'm betting the bypass hose off the water pump is leaking, it's right above and behind the pump. I'd do a good degrease of the whole engine side and front and see what is going on.
If the waterpump and hoses haven't been changed, I'd at least do all three hoses, that waterpump best I remember was about hundred dollars

Thanks very much I'll clean it up real well and take a few more pics. Hopefully I just need to replace those o-rings? Is this something a person with moderate mechanical skills can do alone? I can change the piston on a two stroke dirt-bike and fix minor issues with my car. I definitely saw some green fluid coming out but it also seemed a little greasy or slippery so maybe it was mixed with hydraulic fluid? Like you said might be two different leaks.

So after some research I think the problem might be fixed by replacing seal #5 and #6 in the priority flow valve like joe recomended. Thanks.

 

[maxamillion125]

Ok so is this a pretty simple repair? Easy as taking it apart and replacing the o-rings then adding some hydraulic fluid when i'm done? Thanks for the help guys.

Are you sure of even what type of fluid you're leaking? It looks like it would be hydraulic fluid but it may something behind and above and running down masking it as another leak. If its coolant I'd be looking at that rubber hose that tracks behind that pump and goes towards the radiator along the frame.

I think you are correct.

 

[maxamillion125]

I think you are correct.

Is there anything I should know or look for when taking it off to replace the o-rings? Is there a shut off valve for the fluid or is it just going to all drain out? Anything I should know about replacing the hydraulic fluid?
Thanks

 

[maxamillion125]

I cleaned up the area and took some more before and after pics. Do you guys still think its the o-rings? Its power steering fluid correct? and how hard is it to replace those parts or should I just take it to a shop? Its only leaking from that one spot
Thanks

It looks like you'd just drop the bottom lines off, undo the valve and drop it straight down. Doesn't look like much, but I bet it would be a couple of hundred at the dealer! I guess it would depend on your confidence level, and your wallet!

It also looks like water contamination in the hydraulic fluid. I'd change it and filter too.

The oring change looks simple, give it a rip. Plenty here to guide you if you get stuck.

 

[maxamillion125]

I ended up driving it to the hydraulic shop just up the road and they replaced all the o-rings and now its good to go. Cost me $120. Thanks everyone

Well guys the leak returned a few weeks ago. Should I even bother replacing the o-rings again or do I need a whole new priority flow valve unit?

Just curious, have you priced a new valve?

 

[Soundguy]

depends... are the areas the orings seat pitted?

was it loose?

was the wrong oring material used and they disolved?

 

[maxamillion125]

4 of the frame bolts that go into the engine were loose. After tightening them down the leak slowed way down. It still leaks but very very little, a drop every few minutes. I think if I replace the o-rings again and with the bolts tight I should be ok? Thoughts?
