Identifying hydraulic parts

[Jay4200]

I am going to add a couple of remotes to my L4200 using my PB circuit (previously backhoe only) to run my snowblower hydraulics, but have been having trouble identifying the existing parts to which I have to connect. My backhoe and snowblower have the same male quick-couple connectors on their hoses. All of the remote connectors that I have ever seen look the same too - a guy at the dealer called them 1/2" something. What I need is a link to drawings of the common connectors, so I can measure what I have and compare, I guess.

Also, I was looking at valves at that Surplus on-line place - it looks like I can get a suitable 2-spool DA valve set for ~$140. There are also lots of valves with no handles that all seem to be ~$40. Do the handles cost $100? I really wanted a joystick, which seems a perfect match for chute control, but they are a bit pricey. OTOH, dual sticks would be better for future universal use.

What do folks typically do for mounting brackets? I have to re-mount my existing PB connector bracket (will interfere with 3pt hitch when hoses are connected) and have to mount whatever new valves I end up getting.

Lot of question Jay...Have you searched at all?

Here are some quick answers:

Here is a thread chart I use Hydraulic Warehouse - Size Chart to identify fitting styles.

The $140 valve is all you need, making your own handle is a PITA, and yes-they can be expensive if you can find them. Joystick valves can be bought for $180-$220, so they are not that much for in the grand scheme of things.

I welded a plate to my ROPS crossmember, some use U-clamps to clamp a mount to the ROPS.

Yes, quite a bit, and still can't find anything that has measured drawings.

I think you posted that link for me before. Doesn't help in this case - am not matching threads. I don't have any threaded ends - all of my hoses are connected. I will have to get new hoses and threaded connectors eventually, so I'm sure I'll need that sort of information, but for now, I am trying to figure out what size female connector hooks up to my existing piece of equipment (w/ male QCs). I don't know what they are called, don't know what size they are, etc. I have existing quick-connect fittings, and have been trying to find out what size/style they are for over a month. I can't bring them in to a shop since they are connected to 1500 pounds of machine. I have measured them, so I can produce a rough mechanical drawing of the connector - which should make identification trivial, but I have yet to see a chart that shows measured drawings of the fittings. For example, using a link out of the chart that you posted, there are 3 kinds of quick-connects shown that look like mine: Ag Interchange, 7241 Series A, and 7241 series B. Which one do I need? Don't know - they all look alike to me.

Yes - it's not so much the cost, but I don't really want a float feature, and I don't think I can get a joystick w/o float. I still might go with one though - I joystick seems the perfect control for a hydraulic snowblower chute.

What makes things really hard is that I have to mail-order my supplies, so I have to make sure I know what is going on 100%. It would be awesome to be able to go to a hydraulic supply house and browse around and ask questions and learn about the jargon and . There is one about 20 miles away, but I can't go there during their operating hours because I have a job. It has been very frustrating, especially since my last foray with local 'experts' yielded bad information and steered me wrong for a while (never take advice from someone who wants to sell you something). I did finally learn enough to understand the basic systems, so now I just have to figure out the fine details.

Those QD's are removable, so take one of them off and send it to a hyd supply company, or someone like Northern Tools, of Surplus hydraulic. If you look at the number on the QD that you have, it can be matched up. I have posted charts of different manufactures part numbers.

Just tell them what you want and ask them to give you an estimate for the parts.

Here is a QD interchange. Hope this helps.

Just because the valve has float, does not mean you have to use it
