6420 hyd lines under cab???

Anonymous-0 · Feb 23, 2014

I have some oil leaking under the cab of my 6420 and I think I found the culprit. It looks like a line that seems impossible to get to without taking the cab off. Is it possible to remove the seat and the bottom plate to access these lines under the cab? Thanks.

I've got a 6410. There's a plate under the floor mat on the left side (setting in the seat).I'm not sure where those lines are,but I used this hole to get to a leak on top of the fuel tank.

There is a plate in the floor under the mat about 16" x 24"in front of the seat.
I have not had to move the cab for any hyd. line changes on these tractors. BTW they tip them sideways to the right for transmission removal.

There's a removable floor plate AHEAD of the seat, under the floor mat, that allows SOME access to the stuff cleverly hidden under the cab. But behind there, removing the seat simply gives you access to the HVAC system!

I just repaired a similar problem with a 6420, it was the brake valve return line. Some quality hose coming from up front is spliced to some thin/crappy hose with a plastic barb, and the leak was in that area, in the LH upper frame area behind the fuel tank.

Once I put ALL dignity aside, and removed the plastic fuel tank and laid there with oil and debris falling in my face, the leaky splice was (almost) access able through a teardrop-shaped hole in the framerail.

I wonder if you are having the same leak?

Doesn't leak much, but puts a quart or so of oil on the ground if he tractor sits in on place for a week or two!

Post back and let us know what you find!
