Every 1000 working hours or once a year the fan clutch is dismantled
for inspection, cleaning and lubrication.

3. Polish the two axles (C) of the core with a fine emery cloth to
remove dirt and rust.

5. Check that the discharge hole in the ferodes (E) is not blocked.
6. Lubricate the axles of the wings and inside the core lightly with
oil before re-assembling.

8. Re-assemble in reverse order.
WARNING! If the clutch is not maintained it may malfunction
and cause severe damages to the fan unit!
Every 1000 working hours - Fan transmission shaft inspection
Every 1000 working hours or once a year - whichever comes first - the transmisson shaft between pump and gearbox is
dismantled for cleaning, inspection and lubrication.

3. Detach the suction and pressure hoses and the 4 bolts holding the pump. Lift the pump away.

5. Separate the male and female part of the shaft.
6. Clean the profile tubes (inside and outside) thoroughly with a degreasing fluid (Alt. petrol, white spirit or similar)
and wipe them dry.
