B2601/LA434 Quick Coupler Leaking

[ovrszd]

When I say quick coupler I am talking about the hose coupling. One end female. One end male. FEL end has hose attached that runs forward to the loader.

Is that what's leaking??

When I say quick coupler I am talking about the hose coupling. One end female. One end male. FEL end has hose attached that runs forward to the loader.

Is that what's leaking??

Yes. But on the 435 all four hoses are attached to two common plates. The lower plate has the four male connectors. The top plate has the four female. There is a cam lever that connects them all at the same time.

Because they are all connected simultaneously and actual connections are covered by those plates, it's hard to tell which one is leaking. If you look the third page of this pdf you'll see what I'm talking about. Couldn't find an independent image.

Okay. So it's a quick coupler leaking. Which one doesn't matter.

Almost all quick couplers will leak when all pressure is released. They require some pressure to seal. Your previous comment about parking the machine and then later it drips on the floor is acceptable. I have never heard of a fix for this.

It's losing about a cup to a pint. I think that's excessive.

Yes, that's excessive for sure.
