Quick Connect Incompatibility?

[Newkirk]

Hey folks, I just got a nice new Salsco chipper to use with my Kubota L48 tractor. Everything hooked up fine except the hydraulic lines, which I can't get to snap in for the life of me.

I notice all the Kubota quick connects (male) have a little nipple on the end whereas the Salsco lines have a little stainless steel ball. Are both these supposed to be compatible with the Kubota female side? Or is this an Ag hydraulic vs. Series B issue and I may need to swap out the Salsco fittings?

Thanks in advance from Colorado.

I think you nailed it with the ag vs. Series B.

Sounds like you have ISO 5675 connectors on your chipper, and ISO 7241-1 series A
on your Kubota. My understanding is that you can mix them for only one or two
sizes. You may have the non-compatible size.

Or you have ISO 7241 B on the Kubota.

I have not tried it personally, as I have only had ISO As and Bs.

Have you got all the pressure off of the lines and tractor?

They should interchange without any problems. Sometimes the male ends are a few thousandths off though and for whatever reason, they just will not mate up properly. It is possible that you might need to get some new male ends.

This is correct. ISO 5675 and ISO 7241-1 Series A are interchangeable ONLY in the 1/2" nominal body size. All other sizes are not interchangeable.

Or you have ISO 7241 B on the Kubota.

Which do NOT interchange with any of the previously mentioned couplers.

I'm thinking this may be the case. Pictures of rig below and of chipper hydraulic connector. Connector on the Kubota side says PARKER SERIES 60

[ISO 7241 B connectors] do NOT interchange with any of the previously mentioned couplers.

I think HHG nailed it - I just downloaded Parker Series 60 spec sheet and it says:

"Industrial Standard: Parker 60 Series couplings comply with ISO 7241, Series B Standard"

So that seems to be the problem. Now - where to find matching nipples? I don't suppose they'd have 'em at Big R or Home Depot

Local Kubota dealer, any tractor dealer? Discount Hydraulic Hose, me?

Good luck

There are a myriad of different hose connectors and some of them look almost identical visually. You have to look at the numbers and match them. As for ball end or pointed end, those will interchange as long as the number type is correct. I broke 2 of the male disconnects on my LS FEL and looked high and low for them. The LS dealer didnt have any in stock nor did he have any old ones lying around in the mechanic shop. I finally discovered that New Holland used the same type and got ONE from stock which did me no good but ordered one and got it FEDEX to house 2 days later. The FEL connectors arent the same size as the remote rear hydraulics which everyone seemed to have a good stock of those. I had a sample female connection with me and still dealers tried to sell me the wrong one "as this is what the book calls for" but it wouldnt fit the connection. I dont recall the fittings having part numbers on them other than size which made it hard for me.

I have the same model Salsco that your picture shows and run it off a JD. I presume your Kubota PB has one female QD on the supply side and one male on the return side which you plug into the supply side when the PB is not in use. (Both 1/2 inch QD) I presume the fitting picture you show is the supply line on the Salsco (you said it had a ball fitting not a poppet). When you stated that you could not get it to snap together I and everyone have been assuming that the fittings do not match. I am on the road and do not have mine to visually compare nor due I have the catalogs to do a visual comparison of the grooves on the nipple but that looks like the one I have. My Salsco came with 7241-B compliant fittings.

Since you can not get them to snap together could it be pressure on the internal lines of the Salsco. I had it happen once when the weather was very hot that enough pressure built up in the Salsco lines that the ball could not be depressed so coupling could not occur. Did not make sense but it did happen.
I presume the Kubota has been turned off and pressure relieved on the PB as you can not plug in under pressure.

Have you tried to depress the ball on the male end of the Salsco? If it will not depress with your finger you may have pressure on the line that is preventing the hookup. If so take a wrench and loosen one of the fittings on the Salsco and relieve the pressure. It can be on the male or female end and hopefully they are not both NPT fittings but are ORB as NPT fittings can be a pain to just loosen and retighten. Have you tried to plug the Salsco male into the Salsco female and had them mate properly? That would also remove the pressure question from contention.

You will love that unit. It looks like you got the speed sensing unit as well from the picture you posted.

Yea the pressure thing happens with my FEL when I take it off outside, the sun must expand the fluid and create pressure on the lines. If I try to hook it up in the evening when it isn't in direct sun light there isn't a problem go figure! The first time I had the problem it took me like an hour to hook up the loader that normaly takes 5 minutes man was I mad I thought something was wrong, and then I was even madder when I figured it out and realized how stupid I had been, oh well thats what they make beer for!
