4430 Hyd Leak #1

Rich.Fl · Mar 13, 2017

I have a 4430 that has 2 hydraulic fluid leaks which are bad enough they need to be fixed, and I can use some help. I will list them in separate posts. Leak #1 is where a line goes into a structure that I can not identify or find in the parts diagram.

I attached a picture. The leaking part is on the left side of the tractor just behind the hydraulic fluid filter. It is leaking where the line screws in...I have tightened this as tight as can be. Suggestions?

Thanks!

You will need part #B2762R...number 5 in the picture, it is kinda like a compression nut to the o-ring, a lot of times the line is frozen to the nut and you need to cut the line to remove it,, then buy the line #1..AR74312,,and the nut#4...R76494

It's the hydraulic filter relief valve.

There's an "O" ring in there, Key #3, B2762R.

Or, the line may have a crack or a rusted pinhole.

Bob and TimS-

Thanks for the information and part numbers and diagrams (I would have never found them.) I should be good to go with that.
Thanks so much, very helpful!
