Spool or control valve rebuild

[In Utopia]

Was there someone here that rebuilds spool valves or whatever they call the valves that control the FEL on my L175?
It's started to bypass and the float function doesn't work properly when the fluid gets hot.

You can buy the valve from Vevor for $68. are you certain the valve is the problem? serviced the hydraulic system, test temp and flow, and the cylinders?
Can you explain what you mean by "it starts to bypass and "the float function doesn't work"?

Fairly sure it's the valve, I recently rebuilt all the cylinders, rods were all good, no leakage there that I know of. The float function has always been a little suspect, worked almost all the time, often it would disengage while back dragging. Haven't checked pump output, but it seems to be OK since I can lift the same 600lbs deer corn with the same amount of effort. Thing is when doing that while load is up it bleeds down, not much, but at about 1000rpm it does bleed down a little, never did that before.
Heck for $68 I'd take a chance on that being the problem.
Get to it soon as I can, right now trying to let the body heal from a fight me and my 640 Ford had with an Oak tree........I lost, broken clutch pedal and bent steering wheel on the Ford.

Is this the valve you're referring to? Would something like that have a float function since I like using it to back drag? Just looked at the F&Q, and it says it has float function, then couple of answers later it says no.

Thanks

The only rebuildable parts in these loader valves are the external seals and the return/detent mechanism. If it's leaking internally the only fix is a replacement. There are a lot of inexpensive valves that will work in your application. Post a picture of your old valve and I will suggest some possibilities. You can spend a lot or a little and everything in between

Please don't buy a valve for $68, just light the cash on fire and save yourself the hassle of changing the valve twice.

And your recommendation is?

The Vevor valves are real mystery boxes of unknown origin. I would not equate buying one with burning currency but you can get the sane design from known origin for not much more money. Here is one source for a true loader valve with joystick control. They offer a two stick version for a good bit less. Don't forget to buy the power beyond sleevexwhich is sold separately.

Hydraulic Directional Control Valve for Tractor Loader w/ Joystick, 2 Spool (Single Float Spool Optional), 11 GPM

FREE SHIPPING This Monoblock Hydraulic Directional Control Valve uses a Joystick, 2 Spools and has a capacity of 11 GPM. These valves are used to start and stop fluid flow into hydraulic cylinders or hydraulic motors.

Anything NOT from Vevor. They slap their label on the cheapest of the cheap products and are flooding the US market them. i swear they are an arm of the CCP. But I digress...

Prince, Bucher, Wolverine, ect
Look at the Surplus Center for some options.

Thanks for the warning on Vevor.
Started to look at Surplus Center, got very confused as to what to buy.
Also after looking at the pricing, I'll probably run till failure. Right now I try to keep the old L175 running as close to new as possible and the only reason I thought about replacing the valve was with a 300lb load it would very slowly leak down at 1000rpm. Nothing I can't live with by just raising the RPM.
The float function not working consistently is something else I'd like to fix, but it looks like pricing of a new quality valve is not in my budget.
Thanks again.

As I said you can spend a lot or a little. Picture of the old valve please.

I am not able to send a pic right now, I’m laid up from an accident I had while on my Ford tractor. Got into a fight with an oak tree, limb and lost. Spent several nights in the hospital with a collapsed lung, large hole in my left leg in, multiple sore spots on my interior. No broken or bruised ribs.
Orange tractor is 300 miles from where I’m at now, but maybe I can get my neighbor who is taking care of deer feeders and stuff to go over and take a picture of it.

 

[Lil Foot]

Wow, sorry to hear that. Hope your recovery goes as fast and as pain free as possible.

I'll try and keep this short. I was shredding an area I've done dozens of times before, crawling around in low gear.
Next thing I can remember is being doubled over still sitting in the seat, motor running, tractor not moving. Reached around shut the motor off. Hobbled to the house, called a neighbor and he drove me about 54 miles to the hospital. They inserted a chest tube for the collapsed lung the then off to the trama center in San Antonio. No bruised or broken ribs, fractured left fibula, hole the size of half dollar in the left leg, about 75% of the skin scrapped off my left arm.
Looking back, it looks like limb caught the left tire and the tractor spun around somehow bringing the about 6" limb around, came down, hit my back pinning me down continued down, bent the steering whee, then hit the clutch pedal, broke it off and kept the pedal depressed thus throwing it out of gear and kept the shredder from running.
Things happen fast, again I have no idea how it happened, and the rehab on this 80 year old body is going to take a while.

Wow, incredible story! Glad you are able to tell us about it.

 

[Henro]

Wow! Agree that is quite an event!

Hope you heal fast! We are certainly all rooting for you!

 

[Tractor Gal]

What an awful experience! Things happen so quickly and of course we don't expect them. Perhaps that's the definition of an "accident?" Like the others, I hope you heal well and quickly, too.

[D2Cat]

Sounds like you got the crap beat out of you. It's painful to see the curve in the steering wheel where you were pinned. Your ability to think clearly and use the keyboard are doing fine! Pray you heal fast!

 

[RCW]

Holy smokes….glad you’re on the mend….glad you’re here to tell the story…

Take care and best wishes for a speedy recovery.
