L3400 change hydraulic pump inlet hose

[nhinze]

I have a hydraulic oil leak on my L3400 that I tracked to a cracked hydraulic pump inlet hose.

It seems fairly straightforward to switch out as it is only held up by clamps and easily accessible.

However, how much hydraulic oil will I lose? What's the best way to minimize hydraulic oil loss? Can I park the tractor uphill/downhill a bit? Or with the ride side up? Would that help?

Depends on where the hose enters the hydraulic tank, top. bottom or side. If it enters the bottom or side you will lose oil. Better off to drain the tank first than to have a big mess!

Don't get that part, there is a newer part, and almost all of the time the newer part is a better part.

The hose is located between the hydraulic pump and filter. It's fairly high up. Here is a picture (not my tractor).

If I remember correctly when I changed mine, Pretty sure, you will not lose any fluid. Let me know if I'm wrong!?!?!

Setting on level ground, you will loose a cup or less of hydraulic oil.

TC220-33332 I think. The original part number is NLA, superceded to TC402-33332 (I think that's the right number--going off of memory). It is a different material that isn't as likely to crack. There was a bulletin at one point.
