Will a 37 loader off a 920 fit a 1020?

Hotflashjr · Jun 11, 2020

I have found a 37 loader for sale locally that came off a 920 diesel which is relatively the same size as my 1020 gas and same vintage. My main question is will the hydraulics work? I can't find much info if the 920 is an open or closed hydraulic system. I do believe the loader was plumbed into the transmission and not off hydraulic outlets in the back. How difficult would it be to plumb this into the transmission on a 1020?

My second question is can a number 37 loader lift 1000 lbs.

According to JD parts 920 has open center hyd pump. 37 loader control valve may be convertible to closed center. According to Tractordata 820 with 37 FEL should pick up 1050#s at bucket pins

So I confirmed and the loader does not hook into transmission but into the hydraulic valves at the back of the tractor. The loader has its own separate controls. My 1020 does not have factory hydraulic hook ups. It is plumbed into the transmission but it has a loader type valve on it already.

Does this play into the difference between open and closed center? I am less sure now I can make this work.

If your 1020 has a double spool valve already attached all you need to do is attach the 4 FEL hoses to your tractor's existing valve & you'll be good to go.

I do not have a double spool valve, only a single. The loader comes
with a double spool valve hooked in already. Could I just plumb that
into the two lines going to and from the transmission that exist
already?

Open center valve attached to closed center hyd system will not allow closed center hyd system to function as designed!!!

OC valve can only be successfully utilized on CC system if valve is designed to accept a CC conversion plug & plug is installed with correct inner seal.

Don't be dorking around with la oader supply and return plugged into the SCV. This topic has been beat to death for years here.
The dual control valves on the loader have to be "re-plugged" from open center to closed center.
Install a supply "T" and a quick connect fitting on the high pressure line between the priority valve and the SCV valve.
Install a ported transmission filter cover to return the loader oil into .

B&D - the tractor has a set of after installed scv’s on it including a
single spool single lever valve body. There is already a ported
transmission cover For the return and a line tapped into the
transmission which I assume is the high pressure side. My question
is if I get an open center double spool valve can I hook it up for the
loader and remove the single spool valve that is on there? That
seems to be what you are saying.

I have read some of the old threads about plumbing loafers and it all
might as well be Chinese to me. I haven’t ever messed with this
before and I don’t want to buy this loader if I cannot make it work.

An open center valve attached to a closed center hyd system WILL NOT ALLOW closed center hyd system to function as designed????

Looks like from jdparts kit AT58789 would change to be used on my 1020 from the 920 the loader is on. Seems that kit is nla so using the existing valve in the loader is not an option.

Won't be hard at all. IMHO, I'd plumb it into your hydraulics like this:

Leave the rear hydro outlets alone for other functions. Get a joystick with closed center plug and you're done. Here's some to look at, https://www.surpluscenter.com/Hydraulics/Hydraulic-Valves/Joystick-Valves/. You'll be money and time ahead by doing it the correct way and not trying to cobble something together, trust me. My 1020 is a 66 model, and had a 37 loader on it when I bought it. I've since replaced the 2 spool valves with a joystick and all the hoses and fittings. Best money spent in quite a while. The loader will pick up 1000#. Hope this helps.

Hotflashjr · Jun 15, 2020

Jim - 100% understand that. Just trying to get an idea of the parts I
need to make it all work and the cost so I can make an appropriate
offer on the loader. Any chance you may have an idea of what I
would need to replace in terms of the correct valve or JD part
numbers?

Hotflashjr · Jun 15, 2020

Thanks! That is currently how the rear remotes are plumbed in as
they are not original and someone added afterwards on a aftermarket
valve. The valve is mounted next to the seat on the fender. I don’t
use the rear remotes at all so I would be fine with deleting them. I
need a good functioning loader way more than the valves. With the
correct closed center plug installed would it be as easy as hooking up
the connections from the loader valve to the connections like shown
in your picture? My 1020 is a 67.

Tx Jim · Jun 15, 2020

Are your sure 37 control valve is original? Can you post a photo of RH side of 37 valve? Yes you can attach a 2 spool closed center similar to current valve on 1020

buickanddeere · Jun 15, 2020

As butt ugly as the home brew SCV system is . I would be tempted to keep it . I hope they used a closed center valve on it ?

Hotflashjr · Jun 15, 2020

So I have used it a few times and it does work. So I assume it has to
be closed center.

Hotflashjr · Jun 15, 2020

Here is the best photo I can get of the valve. I am going to see it in
person tomorrow night and can get better pictures then.

Tx Jim · Jun 15, 2020

That photo is sufficient for me. Does valve have any readable numbers or brand name?

I have a 37 on a 1020, so yes they will fit. It should lift 1000 pounds, but the weak point on these loaders is the single cylinder bucket tilt. This is especially true if you put forks on it. You will also want weight on the rear of the tractor. I broke the "eye" off the tilt cylinder rod a couple of times, so I finally converted it to dual cylinders like other loaders.

" With the correct closed center plug installed would it be as easy as hooking up the connections from the loader valve to the connections like shown in your picture?"

I don't know specifics about the spool valve your pic shows. The spool valve on mine got replaced because it was leaking internally. It looks like the one in your picture, and the mount looks the same as well. Wanted to clean up the installation and replace the hard, cracking hoses that were probably original. Might have had a little mission creep show up, but I was happy with the end result. Relocating the joystick to the fender took a little planning and fabbing up a bracket. All the hoses were stock length from Surplus Center. The boom cylinders were rebuilt by a local hydro shop.
Here's my original spool valve, probably original, who knows?

Here's my "upgraded" joystick.

Here's the right side tower mount with quick connects for the bucket circuit. I take the loader off when haying and not needed supported by a set of stands, only takes 4 pins and a couple of minutes. The hoses were all rerouted under the floorboard

Like Richard in Bee, my single bucket tilt cylinder was converted to two cylinders. Also got them from Surplus Center.

Will a 37 loader off a 920 fit a 1020?
