Deere 690D hydraulic leak

[Jl88]

I think it does but I’m still learning about this thing

So I’ve been doing some thinking and I’m pretty sure it didn’t start leaking this time until it was put into “fast” travel speed…

What's the machine serial number ?

I just wanted to confirm that the propel motors are only 1 speed. When in low speed it looks like the pilot pressure to the propel pedals is reduced . Still doesn't address the problem.
.
I wonder if the case drain fittings are in the correct location on the 2 motors.
Maybe the reman supplier could help with that.

Hey all, I’ve got an old 690D LC that has a bad hydraulic leak at the final drive. I was hoping maybe someone here would have some experience with what’s going on. I read in the manual that it’s not necessary to drop the track to get the propel motor off but I’ve never messed with heavy equipment before so I’m not sure what I’m getting into. It streams out fluid even after you’ve shut the machine off. I took the inside cover off and the propel motor side is all dry, the leak is right at the sprocket… and it’s definitely hydraulic, you can’t even run it for more than 5 minutes without having to add fluid. thanks for any help

Hello Sir, Just seeing this forum and I have the same problem so was hoping you had time to tell me how you made out with your repair? Thanks Ted
