6410 big hyd leak?

DairyFarmerInMA · Oct 13, 2014

Our 6410 with cab & 4 wheel drive & 640 loader had a major hyd leak as it finished running the mixer wagon the other night.
the leak seems to be coming from 1 of 3 hoses.

left side behind the fuel tank inside the frame rail.

there looks to be 2 hoses about 3/8 diameter and 1 hose 1/2"-5/8" diameter they go up around the clutch mechanism and continue forward towards the front (I think- hard to follow at that point) I'm guessing they are return lines and wondering if anyone can tell me what and where they go. Also if we'll likely have to tip the cab. I thing it maybe the larger hose that is leaking but can't tell for sure though.
any help or insight'd be great
Thanks

This old thread may be of some help.

IIRC (but maybe I don't) the larger line is "return" from the steering and clutch valve area, and the two smaller lines operate the brakes.

The return runs high up behind the cab to the main hydraulic pump area.

By chance are these the lines?
