Replacement Loader valve for a V-tek Loader?

[Scotty Dive]

My BLB valve that came on with V-tek FEL took a dump today....literally. I posted over in Hydraulics, but have any of the Yanmar guys replaced their loader valve with a drop in replacement?

Hi Scotty-

Sorry to hear about your loader.

I don't think it would be a drop-in replacement, but I did replace my loader valve recently. It turned into a fiasco because I was trying use a front-mounted pump and separate tank. I couldn't get that to work so I ended up back with the standard setup. You can read the whole sage here if you want. But the upshot is the Brand valve I purchased (about $200 if I remember right) works nicely. I've got a couple leaks I need to fix by tightening things but haven't gotten round to it yet. Otherwise it's a big improvement- curl, dump, regen, and float. I suppose I could get demanding and as for more speed, but it's bearable.

Might try here for identical or maybe you don't want identical. Welcome To Vntractor

Good idea Winston - I will check in with them to see what they are using as a replacement. I have found this one that might do the trick:

What's wrong with your valve? Not familiar with "took a dump".

 

[careyo63]

I believe he said the Tilt. I'm Guessing the bucket. So Tech You can't Dump it. That would be a good one.

 

[Scotty Dive]

What I will call "the tilt rod attachment point" broke off. I really didn't even consider fixing it because I want to get PB and float in a new loader valve.

Normde - I was being silly when I said "took a dump" which I meant that it crapped out and was trying to be funny since the spool that was affected was the tilt down (dump) and up of the bucket.

You can see where it broke in this picture:

Heck that looks like a welding shop could make a better replacement for that broken part.

But I agree, if you're lacking float then replacing that with a competent valve is worthwhile. Another optional feature is Regeneration, I think that re-routes dump fluid into the dump side of the piston to dump faster. I didn't pay the extra $100 for that on my replacement.

Here's a thread where I asked all the dumb beginner questions re choosing and installing a new loader valve. Over 100 replies. Maybe something there will help you get yours set up. That thread includes a link to a similar discussion, there's more info as you read through that. Also note in those threads the back n forth between purists saying 'you can't do that' and others saying 'its worked like that for 30 years, what's the problem'. I decided to set up the replacement like the original and skip adding PB, after considering all the opinions. It works fine.

 

[normde2001]

Missed that link. BLB Control Valve distributors are everywhere. Find one that has your valve.

Just an interim update. And Thanks California for that thread - It is a good read and full of great info. I plan on running my new loader valve with PB to the 3pt. I have the Hoye power steering kit installed and when I went through that I found multiple places that can be used as a return to the tank on my tractor.

So, BLB is primarily in Italy, there are three distributors in the US- I called Beieler who is a BLB distributor and who I have worked with before and they told me that they dont even stock the parts so it all has to be ordered and then shipped overseas. I am more comfortable buying something that is off the shelf and more common. So I am not going with a BLB replacement. I did call VN tractors - twice - the parts guy was not available and the person taking messages struggled with taking my phone number down correctly. I doubt I will get a call back in any event.

So I puled the trigger on a Brand Joystick loader valve with regen, float and PB kit. I think it might be the same one Wooly purchased.

More details to follow.

Are you thinking on using the PB to run your power steering?

 

[Scotty Dive]

That's an interesting idea. The power steering usually takes priority in a system and is the first in the series because the logic is that if something fails you don't want to lose steering. That might makes sense at road or highway speeds on a car but don't think it matters much on a tractor. I will have to think about it but I am sure interested in any thought to doing it that way.

* Current plumbing: 9cc Pump to Power Steering. PS to loader Valve, Loader Valve out to 3pt. Both the 3pt and the steering dump to sump. The 3pt does it internally? and the power steering has a separate hose to the top of the transmission. In this configuration - it all works but I have a Gauge on the in side of the loader valve and if I am working the bucket and if the 3pt raises itself, I have seen spikes that buries my gauge (probably 4500 PSI or more)
* What I was thinking before Todd's comment was : Pump to PS, PS to Loader Valve, PB of loader Valve to 3Pt. Power steering and 3pt go to sump. Loader valve will have to dump to sump as well. I may have to find another plug ( I know of one I can use) or T into the one the PS uses.
* Per Todd's Comment - Plumbing might look like this: Pump to loader valve, PB to PS, PS to 3Pt. STill would have to have the loader valve dump to sump. Not sure what that would gain me. Maybe the loader would be more responsive and the steering not so much? Thoughts??

That does appear to be the same valve I have. It hasn't gotten a great deal of use since I installed it, but I like it. After working the loader a few times, the regen really started showing itself. Nice when dumping a load of dirt or firewood. The float is also nice for clearing the drive of snow- what little snow we had this year. I hope you like this valve. What metal work will you have to do to make this fit? There were lots of comments in my other thread in Hydraulics about how the docs were wrong, or mis-leading. In the end none of that turned out to be the problem. I simply plumbed it like it says in the manual on page D-21.

Let me know if you have any questions. I'll do what I can to help, though I don't seem to be getting notifications to changes in the thread despite being subscribed. Notifications hasn't worked for me for a long time. I just try to check in periodically.

I didn't mess with PB on mine, though maybe I should. Pressure comes from the pump to my loader valve and then on to the 3PT. There were discussions about how/when this can cause problems, but it's the way Yanmar initially plumbed it so I left it. If you're plumbing the PB it will no doubt be a bit different.

You don't wanna hear my thoughts....:confused3: I have no idea if the PB would work for the PS...imagine not because i haven't seen anyone do it. Here's what i think you should do. Figure out a way to mount a power steering pump to the tractor, add an extra pulley to the motor somewhere, figure out all the bugs, and then tell me the clean and easy way to do this:thumbsup:

Wooly - I just got the valve today and no instructions with it. Online shows a schematic, but the pages dont jibe with what you referenced so I am wondering if there is an installation sheet that I am not privy to. Any Chance you still have a copy of what you referred to as page D21?

 

[kenmac]

no reason why the PB wouldn't work for the PS

 

[California]

I don't know much about this, maybe someone can explain.

A PS kit includes a 'proportioning valve' so the PS gets fluid before the loader will. I think this causes the slow loader response at low rpm, in contrast to a non-PS tractor where loader hydraulics work about the same at any rpm.

Anybody know more about this?

 

[kenmac]

I know My loader has little flow to loader at idle.. Need about 1500 rpm for good loader operation, and mine is factory PS.. I can't comment on the PS kit//
Wonder if the proportioning valve is adjustable ??
I once had a drag car that had a adjustable proportioning valve for the brakes.. I could adjust for more or less brakes on the rear of the car

I don't think my valve came with any install instructions either. Here's what I found and used when I installed my valve. Just make sure you're using the section in there that match the actual valve you purchased. I'm not sure how the power beyond will change things if at all. I'm on the road today and tomorrow but Saturday I could take some photos of my setup and post them. I've been meaning to do a post here in the Yanmar forum, just haven't got around to it.
