Mahindra 3510 loader float valve

[Mattyboy936]

I have a Mahindra 3510 with a ML108H front end loader on it. The little picture on the loader control valve shows that it has a float function if you push the lever forward all the way.. mine won’t allow me to push it all the way. It’ll only go as far as dropping the loader. There’s no extension that would push it into float “mode” per se. Does anybody have any insight on how to get my loader float function to work?

It will click forward in a detent mode and stay there
It may take a stronger push to do this, also I would pull up the lever boot and lubricant the linkages on the valve assembly

Right. I know it’s different brands but the John Deere I use at work does the same thing. You push it forward and it’ll somewhat click in and stay there. I have pushed forward with some decent pressure and it doesn’t want to move any further past the bucket drop position.

The float assembly on the valve can fill with crud Depending on age of machine and how the valve is mounted. I believe some and maybe most valves have a drain hole in the cover over the centering spring and detent assembly. If this accessible possibly try spaying some penetrating lube in the drain hole to see if that loosens the detent assembly up.

If cable operated from joystick to valve confirm the cables are adjusted properly allowing detent operation.

Well, I believe it’s a 2004 so if it’s been sitting outside for most of his life, I would assume that could be an option. I will have to take a look into that a little bit.

Does anybody have a manual for the Mahindra ML108H front loader? I was curious to see if there was an exploded view of the control valve for the loader

I have complete manual but it has ML112 Loader. Not a ML108H

I wonder.. would the control valves are the same?

 

[DiskDoctr]

Mine is Nimco 10373-2s (CV 112)

What is it you're looking to see? Maybe I've come across it?

 

[Offroadtek]

I didn't know the 3510s came with the ML108. Mine has the ML112 and doesn't have the float option.

If you haven't found this site, it's good for diagrams.

Here is my loader control valve. The loader is a ML108H and the little diagram shows a float function on it.. and to push upwards past the loader down. If it’s like the other tractor I use.. I’d assume it “clicks” into the float position

 

[oldnslo]

Does the curl dump have detent on it.? If not I don’t believe that valve has float since the spring caps or covers appear to be the same length while detent option the cover is usually longer

 

[Offroadtek]

I'm thinking the same thing from the equal cap lengths.

Just wondering, is that a Mahindra 2810 or a 3510?

 

[kneedeep]

The lever on my 3510 is pulled back to float the boom.
I have to hold it in float, it stayed in detent many years after purchase but everything wears after 20+years

 

[Mattyboy936]

Yeah, it’s on Mahindra 3510. I attached a photo of the little diagram attached to the control valve. It shows to push it forward almost in a detent manner, but it won’t allow me to push it past the loader drop

 

[Offroadtek]

OK, those caps are the same length because you should have the detent setting to the top and to the right.

If it does not want to go into that position it may have something loose inside the springs or they are seized up in the valve.

I was wondering about it being a 2810 because I have only seen 2810s with a dash and levers like that. But I have not seen many 3510 hydros.

Try this site and search model "ml108h". It's got a lot of exploded diagrams of your valve.

Here’s some questions. Maybe a dumb ones but if I unplug the loader quick connects and take that cap off the bottom of the valve to see if it’s stuck or something. Will hydraulic fluid be pouring out or not much since the pump isn’t pressurizing the system? I assume if I take it apart.. I will have to bleed the system? Or is it self bleeding?

 

[oldnslo]

There should not be any pressure or flow under those caps. Just be careful since there might be some spring loaded parts that will want to be escape artists. Depending on lever or joystick is oriented it might want to push the valve spool so be prepared to control that movement also.

Try pulling lever rearward to detent
