Specifications
Problem:
The belt is very noisy, wears quickly and exhibits signs of abra-
sion. The tensile member and ribs can be torn out of the belt by
edge contacts. This can lead to serious engine damage if the
timing belt jumps of a pulley.
Cause:
The V-ribbed belt on older vehicles has six ribs (6PK1748).
The new belt has only ive ribs (5PK1750) to increase the
distance from the ancillary units. According to Renault,
this new belt should generally be installed.
Solution:
Position the 5-rib belt only on the outer grooves of all belt
pulleys; the inside groove must remain free on all pulleys. In
this connection, the generator’s overrunning alternator pulley
should also be checked to make sure that it is functioning per-
fectly and the hydraulic steering pump checked for axial play
(misalignment). Before mounting the belt, remove any abrasion
ines from the grooved pulley using a soft wire brush.
