Deere 110 with BB1284 box blade, not working properly?

[Martian]

Whenever I see 'diverter problems' I'm reading 'money'.

That direct link didn't work for me, I've always had trouble direct-linking a JD parts item.

I'm going to mess around in there and hope I can find some sort of brush/debris that is blocking it and be good to go. Probably wishful thinking.

Looking more like neither of us were right!

I did pay the dealer to go through it. Checked and changed fluids and a full service. I wanted the pros to check it all out so I didn't look over something obvious, but it looks like they may have looked over something as well. My guess is they didn't know that there was the 3 spool rear and didn't try and test it. Since its difficult to get back there without the backhoe on, can't imagine they'd try with it on.

This goes on much further and I'll just take it back up there. I want to check my based for something simple, but I just don't have the knowledge or time to rebuild it.

I found the diagram, and I know why I was reading 'money'. The price of the diverter valve is... $1,549.60. Yep, ONE THOUSAND FIVE HUNDRED FORTY NINE DOLLARS AND SIXTY CENTS! If I truly need a new diverter valve, I won't be using the rear 3 hydraulics for a while. That's a lot of money...

On the other hand, a hydraulic quick disconnect is $27.50... Not getting my hopes up...

I still would change the female QC on that SCV. If the diverter is giving a solid "thunk" when you switch it, it may be ok or at least it isn't wiring. The diverter might be bad or has debris but hose QC are often the culprit. Mine will do the same thing when I don't get them seated right. I also use a neighbors baler with hydraulic tie that gives my port a fit. The way I can always tell is one hose will be super tight when valve is activated and the other will be slack.

I'll look at the diagrams tonight when I can get on the computer. I am beginning to wonder if their might be a check valve on that port. It could also be a relief valve if each SCV has their own. I'm just not that familiar with the TLB setup. I know some SCVs have switchable settings for single, double acting, and motor controls. It couldn't be something like that is it?

Martian,
I removed the links, worked fine last night with a full screen blow up of the diverter with surrounding hydraulic lines. At any rate there are repair kits and replaceable cartridges for the diverter valve. So far I don't see where a diverter would need replacement.

Have to say you may be better served to have your dealer trouble shoot this problem for you. There are so many things that need to be checked to narrow this down and it would be difficult for a person untrained in hydraulics to do this.

I mentioned on the prior page the items 65 and 66 from the Deere illustration these are directional control cartridges for each line section (six total) that screw into the bottom of the diverter valve. Check those out if you will.

Now that you say there is reaction from loader when you activate a rear SCV with the hydraulics diverted from the loader to the rear SCVs, that says the problem is in the diverter.

I would find out what parts are needed to pull it apart and clean everything. There may be a service kit or just a lot of O-Rings to buy.

I think you want 1/2" QCs not 3/4". You can get multiple types of threads (internal, external, NPT, 37* JIC, ORB, ORFS) for the QCs. I would get a female QC with external ORB or 37* JIC threads and a male QC that will thread right on. 37* JIC are same thread as ORB, just add an O-Ring.

The QCs used on my 640 loader have a black collar with a place to put your thumb (the feamle half) to make them easier to use.

You may (for the third on the loader) want to look into the MultiCoupler that uses a lever and cam system to hook up the hydraulics. I saw that set up on a JD 673 loader. The brand used by JD is Faster. Their website has a catalog of just multiCouplers.

Martain, keep plugging away. you got a steal of a deal on it.

I think I will be taking it to the dealer on Monday or Tuesday. I don't know what I'm doing. Like I've said, I'm rather new to all these hydraulics, and even newer to fixing them. If it weren't for you guys, I'd have probably had it back there already. I'll take a look at the 65 and 66, I'm out right now, so it won't be right away, though. I am hoping there's no need for a new diverter and be able to just be fixed otherwise. I would think it's a simple problem still (although possibly costly). I'm also thinking about calling the dealer where I got it and ask them WTF?!? And also see if they actually know what was wrong.


As far as the quick connects for the loader go, I would want the 3/4" because that's what I got in the back and if I ever needed to move a cylinder with the backhoe on, it would be much simpler and easier.

Martian,
Recognize that the quick couplers on the front aux work with most other skidsteer attachments. Not sure I would change these to a different type. I know I have rented a front ssqa Bobcat hydraulic auger and it plugged right in.

good luck with the repairs and keep us informed.

Will do,

I don't plan to completely change the front couplers but have a coupler that plugs into each and 'converts' them to the 3/4" if you know what I mean. That way if I want the other set-up I can just disconnect it and have the normal, plug and have the easier set up to get on and off.
