Almost all the following works require certain experience and more exacting service and
diagnostic equipment. That's why we recommend to do the works at specialized or authorized
workshops.
Adjusting valve clearance
Adjustment of the engine valves must be performed by an authorized service.
Flat belt drive tension of accessories
Bleeding the front drive axle brake system
C18N095
Bleed the front axle brake system with a minimum of 10 bar with the engine running and the operating air
pressure in the system.
Perform the following steps:
1. Check the level of brake fluid in the buffer tank (A). Fill the amount of brake fluid if any missing. Check the
amount of brake fluid in the reservoir for the entire duration of the bleeding of the front axle brakes and, after
the bleeding is complete, top up the brake fluid to the maximum height (3/4 of the tank contents).
Use only the Titan ZH LHM PLUS hydraulic oil as the brake fluid in the front axle brake
system .
2. Remove the caps on the brake discs of the front drive axle (the screws are located on the upper surfaces
of the reducers).
3. Place the hoses (B) on the screws. Dive the other end to the bottom of the transparent bottle partially filled
with brake fluid. Place the container at least 300 mm above the vent screws. The screws must still be under
pressure so that air does not get through their threads
4. Bleed the left and right brakes at the same time
5. Loosen the bleed screws by a maximum of 1/4 turn
6. Depress the connected brake pedals and pull the breather screws only after pulling the venting screws
release the brake pedals
7. Repeat as long as the air bubbles continue to run out of the hoses
8. After the brake system has been bled, the throttle screws tighten to 0.8 - 1.2 Nm and replace the two
screws of the cap (C)
Flat belt drive tension of accessories ( A ) does not need to
be adjusted. The belt is tensioned automatically.
*Tensioning the V-belt of the AC compressor
If the V-belt (B) is properly tensioned - its deflection must
be 5.5 mm when the belt is subject to the force of 50 N.
Tension the V-belt to the prescribed value after releasing
the fixation screws of the AC compressor.
