Yanmar LX Rear Remote Kit Install

[Katahdin]

I have no illusions that Yanmar and my dealer made a little profit off this kit sale, at least I didn't get dinged for labor too! I would have liked to cobble together my own kit from cheaper parts but I just wasn't comfortable. My only other hydraulics experience was replacing a chaffed snow plow hose and I was worried about jeopardizing my tractor's warranty or worse. Do any of you remember reading about the John Deere owner who got his hydraulic lines crossed in a mishap, the engine wouldn't start because the hydraulic pumps were now put a load on it, the dealer couldn't figure it out, a whole new engine was ordered, installed, and that new one wouldn't start either because the hydraulic lines were still crossed? Well, I remember reading about it and I didn't want to be that guy too. :confused2:

The extra downtime involved to fabricate and fit the parts was another issue. I needed the tractor to plow snow on a moments notice, and since I am neither a pro mechanic or fabricator it takes me a lot longer to figure out and do things. Due to my job my only shot at working on this stuff is on weekends. I am really happy the weather cooperated and I was able to fit the install into one weekend, the kit and the instructions helped with that.

I know JJ's comments are well intended and he is extremely helpful with DIY kits and troubleshooting hydraulic issues. I've read a few of JJ's posts, I don't yet understand most of the technical jargon, but some day I hope to. This kit installation was a good exercise for me, I did learn a lot and the factory instructions and parts were a good safety net to prevent me from screwing up the tractor. If and when I add any auxiliary remotes, or a loader third function, I will very much consider cheaper alternatives and feel more confident about it now that I have this experience under my belt.

FYI, I paid for the kit with some inheritance from my Dad that I've been sitting on for the last 5 years or so. My father was never good with money. I mean...really not good with money...I'm surprised he had any left over, and what was left had to be split between 6 kids. Everything being said and done, I think he would have approved how I chose to spend his money.

In any event, if you get done reading about my rear remotes kit installation and come away thinking Yanmar put together a quality kit and that I wasn't a complete idiot at installing it, then great. If the knowledge is helpful to you to install your own kit, either from Yanmar or from alternative cheaper parts of your own choosing, I'm fully supportive of that too.:thumbsup:

And now you're ahead of me, I haven't ordered my TNT kit yet.......

Since Brian has all the LX top and side link measurements now this should make buying a kit easier for you!

I'll post some pics and video after I get it installed.

Just following up with an answer to a question: Yes one of the spools has float, this picture shows which one.

If you have the time doing it yourself will give you more satisfaction and may save yourself a little bit of money, but I could make more running my business for the time it would take to fabricate all this crap to work correctly, chasing down parts etc.. If I were retired it would be no question that I'd do it myself but no way in **** I'd do it now unless it was a "fun" project for me. Those lines are probably bent by machines BTW! I like the 450, size is just right. I have an ex3200 and wish it were just a bit bigger. How does the transmission work on those?

Reviving a thread from the dead....

Buddy has a LX4900 with what yanmar calls the rear auxiliary hydraulics...(not remotes). They are simply the backhoe connections that when backhoe is removed there is a line that loops them together.

One line comes from the loader valve (the line you show removing in post #6 first pic). And the other line goes to the top of the trans under the seat. I assume thats the 3PH and the other end of that line you show removing in post #6.

He is wanting a toplink cylinder and wanted to just put a valve on the backhoe connections. But I told him he cannot do that as NO power beyond on a 2-hose setup would blow the seals in a new valve. And that those two hoses can be re-used for P and PB but would need to add a tank line teed into the system.

Seems like a well though out plan until I looked at the sticker where the backhoe hooks up. One is labeled return and one is labeled OUT (as in out to backhoe or supply). Problem is the one labeled return is the hose going to the loader and the one labeled out is going to the 3PH.

I would assume this is backwards. And that the supply for the 3PH (and now the backhoe) originated from the loader valve, and that hose you removed was the PB hose going on to feed the 3PH.

Either the coupler bodies were installed in the wrong positions on the bracket, or the sticker was upsidedown or something.

I havent looked at the backhoe yet to see which hose is ACTUALLY going to the P port on the valve and which is the T. I would think if it were actually plumbed backwards and it was supplying the T port on the backhoe valve that it would be a leaky SOB by now with 900hrs and probably 1/3 of that with the hoe in use.

In any case....if this is plumbed like MOST tractors with the PB coming off the loader.....the plan is as follows:

Take the hoses off the backhoe supply couplers and plumb them to a new valve.
Get a TEE and tap into a return for the tank port of the new PB valve.
Two new hoses to supply the existing backhoe couplers.

Thats it. I know it wont be standard ag remotes....but the ONLY thing this will be used for is the new toplink and the backhoe (using for the backhoe would be why I dont want to change couplers).

The valve would be a 4th position detent valve for when using the backhoe.

So basically just looking for confirmation that the the flow does indeed originate at the loader valve and its not backwards. The loader valve ports are NOT labeled
