Tools for Ford and Volvo elastic belts 8 & 9
It is not possible to mount the elastic V-belt on these Ford and
Volvo models (generator belt) using the universal tool. The problem
comes from the water pump pulley that does not have an edge and
because of this the belt is not withheld and therefore would slip off
continuously.
Belt assembly tool No.8 is secured to the water pump by means
of the clamp. When applying the tool you must pay attention to
position the tool's 4 holes on the 4 heads of the screws of the water
pump pulley so that the tool adheres flat. (Fig. 6&8)
Turn the belt application tool at least 180° using the hexagonal
drive.
Aluminium tool No.9 is placed on the crankshaft pulley to keep
the elastic belt in place. In this manner you avoid passing over the
external position of the double pulley. (Fig. 7&8)
You can replace the second belt, the shorter one, depending on the
type of vehicle, for the air conditioning compressor or the power
steering pump, using the aforesaid assembly tools.
