max 26 loader control issue

[linuxman51]

This problem sort-of existed before my previous post (about the tab breaking off of one of my spools), but since then it's been much worse. I did not take apart the valve body at any point, so I'm not sure what exactly happened with this.

I played around with the linkage a little (there's not much to play with there though) to no avail.

If you didn't watch the video, the curl valve on the FEL control has a lot of "slop" in it, in fact, the bulk of movement from the spool is nothing but slop. at the very far limit of curl you get a little resistence, on the dump side of life there's a little more to it, but it's still very slow even at full rpms. I'm not low on hydraulic fluid (I don't think, I checked the other day and it doesn't appear to leak any at the moment.. knock on wood..)

I noticed the back end of the valve body has removable caps, is there anything back inside there that could be used to adjust this out? I'm fairly mechanically inclined (I build my own engines and transmissions) but I don't really want to take a bunch of stuff apart if there's no need.

It sounds like you have a broken spool. Centering spring under cap. :thumbsup:

centering spring under which cap? Anyway, the dump action has gotten incredibly slow, soon as I finish pushing a few things around the yard I'm going to have to take it in and bend on over, since the loader only has a 1 year warranty on it. Probably going to check my agreement and start figuring out the best way to get rid of this and get something... different. I've not been pleased with the ownership experience with this max26. My 28 was a far superior piece in almost every imaginable way :-/

Resolution!

I am not what you might call a patient person, and I had work to do this morning that really needed bucket use (rains coming in, and that wrecks the yard for equipment use for weeks sometimes), so... I took the **** thing apart, and discovered that the back end of the spool assembly was falling apart, and crusty and rusty to boot.

of course, upon reassembly, the tractor rewarded my efforts by not cranking. This seemed to be related to the GFS that was created by the oem battery, that's a story that's already been told.

anyway, back to work.
