1.3 CLEANING THE GEARBOX
Cleaning the gearbox
Observe the following when cleaning the gearbox:
1. Only use weak acidic cleaning products. Do not use alka-
line cleaning products.
2. After cleaning, the gearbox must be thoroughly rinsed
with clean water.
3. The water temperature during cleaning and rinsing must
not be greater than 70 °C.
4. The water pressure during cleaning and rinsing must not
be greater than 70 bar.
5. When spraying the gearbox, maintain a minimum dis-
tance of 50 cm between the gearbox and the sprayer
nozzle to avoid damage to the gearbox.
6. Plug the bleed openings and do not spray directly at the
bleed openings.
7. Do not spray directly at electrical components and elec-
trical connections.
8. Do not aim the spray too long at the same place, because
this can result in the penetration of moisture.
Comments
• Give special attention to the strengthening ribs on the top
of the gearbox because water could remain behind them.
• Make sure no water that contains cleaning product is left on
the gearbox.
Avoiding damage to the paintwork
The ZF gearboxes used by VDL Bus & Coach have a paint
layer applied to them during manufacture. This layer of paint
is intended to prevent corrosion of the gearbox housing.
Corrosion to the gearbox housing may eventually lead to
holes in the gearbox housing, which will allow water to pene-
trate. This will, in time, lead to the gearbox no longer working.
To prevent corrosion of the gearbox, it is extremely important
that the layer of paint remains in a good condition.
An incorrect cleaning method can result in damage to the
paint layer and eventually lead to the paint peeling off.
Repairing the paint layer
If the gearbox’s layer of paint is damaged or begins to peel
off, then it must be repaired. A two-component polyurethane
(PUR) paint must be used.
