On vehicles with air conditioning/automatic climate control, the belt pulley (13) was installed with a hub with rubber part (38, damping part) with ball bearing (40) up to December 1984.
The uneven running of the crankshaft, particularly at low engine speeds and during cutin surges of the A/C compressor, are damped by the coupling so that the V-belt runs practically slip-free on the belt pulley.

Effective 12/84 the belt pulley with vibration damper has been fitted as standard for all versions.
In order to provide greater clearance for the top shock absorber of the poly V-belt tensioning device, the shape of the vibration damper has been modified.
Size "a"=133.1 mm dia., was 145 mm dia.
Production breakpoint 10/1987

With the introduction of the double roller chain
the spacer ring on the crankshaft was made
3.65 mm narrower.
