300CX Problem

[MikeyB]

Hi all,

I have a 3320 with 300CX loader. Man has it been a lifesaver here in Colorado this year! Out moving snow again tonight for the 5th week in a row. Anyway, the hydraulic hose retainer on my loader keeps breaking. This is a plastic clamp and zip tie that attaches to the loader frame via a pin to keep the hoses from rubbing the side of the hood. I replaced this previously and it has now broken for the second time. Anyone experience this or have any advice? I did reroute my hoses the correct way with the quick connect fittings pointing up as I believe is correct after reading a previous post.

Thanks for any help,
Mike

Mikey, if you are continually breaking the heavy cable ties that hold the hyd. hoses to the boom there has to be some sort strain on them. In other words when you are working the loader the hoses are pulling and snapping the ties. Here's how I rerouted loader hoses on my 300CX. I moved the metal clamp to a lower loader hinge pin and removed the hose pin altogether. Set up this way it keeps the hoses farther away from the hood. Hope this helps. Sincerely, DIRT

I am not intending to hijack this thread, but I have a similar problem with the 300CX hydraulic routings, except mine is at the lower output lines. When I turn the front wheels fully to the right, my R4's are rubbing on those lines. Does this happen with yours too?

The tires shouldn't rub on the hoses even when the wheels are cut all the way to the right or left. You probably need to reconfigure the hoses so the 90 degree fittings are turned up. In this position there will be less slack in the hoses at the quick connectors and should clear your tires. The 300 loader manual has a pic of the hoses in the correct set up.

Dirtworks,

Do you have any more pix of your hose and clamp routing? My fittings are facing up and I thought I had the problem taken care of. I can see how moving that metal bracket might help. I think thats where my hangup is. The loop created towards the top is pulling on that metal sidehorn on the frame bracket at times (hope that makes sense) creating stress I think.

I don't have my loader on at the moment. I do have some more pics,but I'm not sure they would help. What is it that you need more detail of? Maybe you just need to slide the hoses within the clamp so that when you work the loader its not pulling the hoses. I can take some more pics if you need me too.

Thanks for all the replies. I guess I will detach the hoses yet again and adjust the top fittings to get a nice straight run and then reclamp and keep my fingers crossed. Glad I bought a spare hose retainer when I fixed it last time.

So these 90Deg output fittings should be facing upwards?

Champy, on the 3000 and 4000 series. Yes,up.....Actually the 300 loader manual has a pic of the quick attach hyd fittings for a 790 without a 90 degree fitting on it. It shows a straight fitting running into the two x two connectors. I assume the 990 would be the same as a 790. And just when you thought you had it figured out. It looks like the straight fittings would work better than what you have in the pic.

FYI - For those of you who may want this later, here is a link to the online version of the Deere Manual for the 300CX. I cannot verify if this is the absolute latest revision or not.............

Hi all,

To update you. I disconnected all my hoses, laid them out straight, and adjusted the fittings on the loader arm so they would all point correctly. This made a huge difference and I'll cross my fingers that problem is now solved since I'm on my last plasitc hose retainer.

Thanks for everyone's help,
Mike

Its all up to the guy at the dealership who set up the loader. If that guy follows the directions you shouldn't snap any cable ties, nor should any of the lines rub.

Don't assume that yours is correct just because that is the way it was when it was delievered. I used to set these up myself. There is plenty of room for error. I watched some of the other techs do it the wrong way once and a while. Of course I was just the punk kid who didn't know anything at the time.

 

[Champy]

MikeyB - Did you have any issues moving the fittings? I was concerned that trying to move them would result in dumping fluid everywhere.....if not then it must be a retainer nut to loosen then rotate the fittings? (I'm not able to look at mine right now)...except now that I think of it I have a problem with the lower fittings and yous was the upper ones.... anyone have input?

Thanks

Champy,

I loosened the fittings on the loader arm that connect the hose to the hard lines going down the loader arm to the hyd cylinders. With all the hoses laid out and the fabric sleeve pulled back you can turn each hose to get the qd fittings pointed in the right direction (up). The only problem is you really need a helper or 3 hands. Two fittings on the hardline and a third swivel type or similar that can be turned after the fittings are loosened to adjust the hoses. But, when you tighten everything up again its hard to hold the swivel hose fittings in position. Hence a helper or third hand is really helpful.

Regards,
Mike
