Man TGA - Step-by-Step Guide for Bleeding Gear Lever in MAN TGA Truck

Hello. I need step-by-step instructions on how to bleed the gear jack in a Mana?

What has changed in the layout that you want to vent?
Is the selector covering the cover dry?
Do you have O-ring on the right side of mechatronics?
Check if all valves are turned on - on mechatronics.
Is liquid leaking from under any valve? - it is loose from the inside, if so.
Of course, it is flooded with the correct non-dot-hydraulic fluid.
You need to connect under the external nipples in the mechayronics to the liquid tank (the same method as you bleed the clutch pump) you give the pressure 1.5-max 2 bars, unscrew one nipple from the top of the mechatronics and you give the jack with as much as I remember correctly - you look for slack - you need to feel how the fluid overflows the jack - if it gets stiff it is ok.
Now, aside to the left, unscrew the rear nipple and look for gear 1 -2 with the jack - you do everything at a slow pace.
And ready you are enjoying your further ride.
More pressure will overflow your fluid and you will not bleed the system.
Of course, you give the fluid under pressure from the mechatronics side

At one time, when I was looking for information, I came across such a document. Here from a Mercedes, but if I associate it correctly, it's analogous. As a colleague wrote, remember the right fluid. If you are not sure, enter the original number from the selector - we will check.


And description taken from another forum:

Easiest and fastest? Two hoses from the fluid reservoir to both cylinders. Connect the ventilation hose under the hood with the liquid collection container. Set actuators in neutral position, release all vents 0.5-1 turn and introduce fluid under 2-2.5 bar pressure. During this time, move the jack to each end position until the outflow of air bubbles stops. set jack to N, close vent,
drive in all directions for pressure compensation. End.
With a large bank, after such a refurbishment as you wrote, you should have a supply of 3-4 liters of fluid for the procedure. If you run out and release a bit of air, you have a job from scratch.

Here you typically have ZF'ki, Titan liquid for Mana, if DOT / DOT + was mistakenly flooded, vain venting - seals burst ...

thanks Colleagues for help but I still have a question if there is a difference if I can connect the air hose to the expansion tank or do I need a vent from below? Regards

Hi, of course there is a difference you only push from behind.

The air is connected to the container with the liquid, i.e. to the tool you will use when bleeding the system.

I added a link with illustrations (maybe not the latest ones), you can see everything nicely, take a look
