DS 19 OPERATION No. DS 2131-0 Adjustments of pulleys and belts. Op. DS 231-0 144
PARTICULAR POINTS
Adjust the tension of the belts (see Pl. 35).
The leverage for tensioning the high pressure pump belt is 24 ft./lb. (3m. kg.) and the dynamo belt 29 ft./lb. (4m. kg.).
TOOLS
ALIGNMENT OF PULLEYS (see Pl. 36).
NOTE - In order to carry out this operation, it is necessary to remove the high pressure pump (see Op. DS 391-1)
and the water pump belts (see Op. DS 231-4).

Fit the gauge pin bracket (B) in place of the high pressure pump on the boss on the clutch bellhousing, using the
face corresponding to the type of assembly (1 or 2 pulleys) towards the front.
2 Place the rod (A) with the ball end engaged as far as possible in the rear groove of the pulley, the rod resting on one
or both of the gauge pins (C) in the zones “f or “g” for the water pump pulley and for the driving pulley.
3 To adjust the alignment of the driving pulley or the water pump pulley
a) Using a set of feeler gauges, measure the gap between the gauge pin and the rod.
b) The rod resting at “f”, reduce the thickness of the pulley adjusting washer by three times the amount of the gap “d”
measured at “g”. The pulley is in alignment when the gap is between 0 and .003” (0 and 0. 08 mm).
c) The rod resting at “g”, add to the thickness of the washer, twice the amount of the gap “d” measured at “f”. The
pulley is in alignment when the gap is between 0 and . 007” (0 and 0. 12 mm).
4 To adjust the alignment of the dynamo pulley (Cars produced since May 1959.)
a) Using a set of feeler gauges, measure the gap between the gauge pin and the rod.
b) The rod resting at “h”, reduce the thickness of the pulley adjusting washer by five times the amount of the gap “d”
measured at “i”.
The pulley is in alignment when the gap is between (0 and 0. 1 mm)
c) The rod resting at “i”, add to the thickness of the washer, four times the amount of the gap “d” measured at ‘‘h’’.
The pulley is in alignment when the gap is between (0 and 0. 1 mm).
