Hello;

I just bought a JD 322 with a 44 loader, rear PTO and 3 pt hitch.

Everything works but the hoses coming from the control valve to the lift arm cylinders are pretty ratty (some of the protective rubber layer is coming off).

I have access to a local supplier who can make me new hoses at a reasonable cost but I am not sure what fittings are used to terminate the hoses. It looks as if one end is fixed and the other is a swivel, both female.

Are they JICF? O Ring?

Any help would be appreciated.

Jim

Take the hose off and hand it to the tech. He can then either match the hose terminations or supply the correct adapter fittings to make it work.

Mine are made up while I wait. It only takes a few minutes.

I redid My hoses;; Had a hydraulic shop re do them, put them on the Loader it raised but would not lower.. After fighting it for 2 days , I found out what was happening ,was/is The couplers that I bought new from the Hyd. shop had a different pressure spring in them,. So I had to buy the Stock over the John Deere shelve. To make them work.. Over the years I have found John Deere does things a bit different ..

Just call You Local JD dealer they can tell You the fitting size I just don't remember the exact size

I was at my local JD dealership this morning and the guy didn't know what fittings were needed.

I am trying to determine the type/size because Princess Auto (in Canada) often has factory made hoses on sale a lot cheaper then having them custom made.

So, if I could say (for example) that I need some 2ft 1/4" hoses with JICF female swivels on each end, I could pick those up this week for about $9 each (Canadian). The last time that I had custom hoses made up, they were more than $30 each.

Thanks for the help so far!

p.s. I haven't taken them off myself because if they are NPT, I believe that they are only good for 1 or 2 tightenings. Bear with me, I am still learning hydraulics.

Hi Jim, I can't speak to your tractor and FEL like the other guys here can but, I can speak to pre fab hoses from an auto parts dealer.
Have you compared ( with a tape measure) the hoses at the store to yours? Im aware you haven't removed yours. I ask because, I've never seen a made hose that wasn't made for a plow Fischer, Myers, etc. at an auto parts store, at least in New England.
I would think (not my strength) that if one of those fit, the guys here would be all over it.

Chris;

Thanks.

The prefab hoses come in common lengths (e.g. 2ft, 3ft). The store also offers a free cutting and crimping service as long as the parts are theirs.

So worst case, I should be able to buy a longer hose and chop it to get 2 pieces with exact length (maybe even losing a bit). The, could put a simple non-swivel fitting on the end for maybe about $8.

So my thought was, let's say I needed a 36" hose and a 46" hose. So the total is 82".

If the hose had NPT fittings, I could buy an 8ft hose with fittings for $14. Chop the 2 ends to length and chuck the little bit extra from the. Have the store put on 2 $8 fittings to get exactly what I need. Total cost = $14 + 8 + 8 = $30 for 2 long hoses.

It would be even better if I just used hoses that are little too long. I have already noticed that the hoses from the control valve to the lift cylindera are a little too short for my liking.

I just don't know what the ends are.

Worst case, I suppose I'll pull a hose and if I can't immediately identify the fitting (I have O-ring and NPT stuff at home but haven't used JICF that I've heard JD likes), I'll run down and have a hose made from the sample while I figure out a better long term strategy.

I have to believe that someone on this forum with more experience with the '44 can tell the fitting types in their sleep.

Makes perfect sense Jim. I haven't seen that before. Pretty cool idea though. Not sure if it helps but all our larger JD stuff (backhoes, dozers etc) use either JIC or NPT everywhere except pump connections. Or where there's a LL disconnect. Post a pic of each end if you can. Not a lot of guys are in the cool kid club with a FEL (jealousy talking) but a bunch of people, like myself, have hydraulic experience.

Changing the hoses because the abrasion cover is ratty is for aesthetics, not function. The aviation industry gets hydraulic hoses without the rubber cover to save weight.

PAL can make the hoses from scratch, or you can buy re-useable hose terminations and the hose in bulk and make them yourself. It comes in 60' lengths maximum, but PAL will sell it in whatever length you want. The crimped fittings are a little less bulky than the reuseable fittings.

Hint: Decent hoses last 20-30 years and more. It's hardly worth the effort to try saving a few bucks on each hose. I buy the ones for my loaders in pairs, one for now and a spare for later, just in case. They invariably go south on a Saturday for me. Usually when I really need the loader. I don't have PAL handy to get a new one on Sunday.

Thanks all.

I think I'll pull one off so I can see what the fittings are. I'd like to replace at least all of the ones from the valve as I think they are a bit short.
