Hydraulic Relief Valve Adjustment for Bx2230 and Bx1830

The shims arrived from Messicks, USPS First Class mail. Order 5/25 arrived 5/29. Pretty good shipping, of course they're tiny, and it was "mystery shipping" until it arrived. USPS First Class is supposed to be trackable and 3 days, but you don't get a tracking #. And my calculations at the USPS show that it should cost about 91 cents to mail, but I paid $14. I know there is some "handling' involved, but c'mon, $13.09?

I have documented the shim specs for those interested, and basically confirm what Tractor Seabee said above. They are 12mm diameter, and look like this:

I put them side by side with some common objects for comparison. Three shims are on the right. I think somebody clever could find a way to jury rig their own shim if they wanted to. The biggest challenge would be to get it thin enough, evenly across the surface.

It takes a lot of work to put those in an envelope.:confused2:

apparently they never heard of a priority mail $5.95 flat rate box through usps also that could hold 1000 of those shims.

Yeah. It's just bad public relations to ding people on shipping charges.

I get it. It costs money to stock stuff, to send a person back to pick it, to packaged it, ship it, and to track the process. But when you try and tell us it's a shipping fee, it just makes the vendor look bad.

I suggest something different, like a "minimum order fee", or such. Heck they could use that to upsell so that we buy a couple of other products to get the total higher.

Wait...Is that really the way you pop in and ask for help?
In a thread where we're talking about different tractors?

Man, if anybody treats me that rudely and expects me to help, they'd better be paying me well.

We all have problems we need to fix with our tractors, sometimes in a rush. But so long as you're just dropping a question in the wrong forums, why not write a polite one just once, and copy and paste it?

Here, I'll even help you. Copy and paste, starting with this:

Hey guys, lots of good information here. Thanks for sharing some of your valuable time to help each-other out. Love these forums!
I'm having a bit of a problem right now, and was wondering if somebody out there would be so kind as to help me.
Insert your problem here

Your welcome.

I apologize for my rudeness , I have never done this or asked a question. I would llike to thank all for heading me in the right direction. AJR

I've been following this thread for a while now and thought I'd add my .02 cents worth. I upped the relief pressure on my BX22 with 1300 hours on it from 1700 psi to a tic over 2000 psi with three .02 shims. At this point its too early to tell if there will be any adverse effects but we shall see. I have not seen anyone post anything negative about having upped their relief valve pressure.

The only thing I can say about working on these little tractors is DO YOUR HOMEWORK before you start pulling wrenches on them. It will save ya some heart ache. Forums such as this can tell you anything you need to know REAL WORLD and not from some tiny hands engineer thats never pulled a wrench in their life!!

I am starting a thread on shipping charges so watch for it. Get that subject away from technical matters.

T SeaBee, I already can see a difference in what the loader will lift with the arms. I have an older Miller Bobcat welder that the FEL would not lift before I shimmed the relief valve. It lifts it easily now. Now, if I dont have the backhoe mounted on the tractor I need to be be even more mindful of what I am attempting to lift.

Like many, I've been looking for a way to increase the lifting capability of my front end loader.

I've researched adding larger hydraulic cylinders and while this is more than doable, the shim change is a lot quicker, easier, and much less costly. I see the stock setup is configured with one solid flat shim and one flat washer. Knowing that by adding a shim simply changes the preload on the valve spring slightly therefore increasing the fluid output pressure. Instead of spending a lot of dough on the item + shipping, I'm wondering if adding a 12mm x 0.5mm flat stainless washer on top of this stack would result in the same performance change?

Comments are greatly appreciated!
