Deutz 4006 Hydraulic System

sammi21 · Nov 29, 2016

We've got a Deutz 4006 that we've just started working on. We are going to replace the starter, but we have to remove a metal hydraulic line first in order to remove the original starter. One end of the metal hydraulic line is connected to a Bosch hydraulic pump, while the other end runs to the rear of the tractor (in front of the shift) and is connected there. My questions:

1. Is this hydraulic line under any pressure?
2. Do we need to prime the hydraulic pump after reconnecting?
3. Do we need to bleed the hydraulic lines after reconnecting?

Does anyone know of any manuals pertaining to the Deutz 4006 hydraulic system? We just haven't found very much information on it. Any help or advice would be appreciated.

With the engine off, and any implements resting fully on the ground, there won't be any pressure on the line.

But if there were, you should get a lot of oil coming out with the nuts loosened, long before the line is completely disconnected. If the line is below the oil level in the reservoir, there may be some gravity drainage. You can either drain the level down, or catch the oil in a container.

No bleeding or priming necessary. Once reconnected and running, cycle any hydraulic accessories through a few times, that will self purge any air. There may be some jumpy, spongy movement at first, but once the air is out, it will return to normal.

The one thing you want to be careful of, for the tractors sake, keep the fittings as clean as possible. If there is potential for dirt to get in the exposed fittings, you can wrap them with plastic bags and tape while working on the starter.
