46 To fit the rear pipe assembly (see Pl. 55) :
a) To determine the number of shims fitted on the outer cylinders.
1. (Cars produced before March 1957 see fig. 6).
Put the 4th speed cylinder together with its adjusting shims (59), on the edge of a surface plate. Using a depth
gauge, check the dimension “r” (see fig. 8). Carry out the same operation to check each of the outer cylinders,
for these cylinders, a dimension ‘s”. The difference of the height is : r – s = t.
This last dimension “t” is reduced by the thickness of the retaining plates (each retaining plate is 0.3 mm thick),
in order to obtain the thickness of the shims placed on the cylinder.
NOTE - In the case where “t” = 0.3 mm, replace the shim by a retaining plate.
2. (Cars produced since March 1957 see Pl. 55, fig. 3).
Put the 4th speed cylinder together with its adjusting shims, on the edge of a surface plate. Using a depth
gauge, check the dimension “r” (see fig. 8). Carry out the same operation to check each of the outer cylinders,
for these cylinders, a dimension “s”. The difference of the height is : r – s = t. Select a shim from those sold by
our Spare Parts Department, in order to obtain a difference of between 0 and 0.3 mm.
b) To fit the pipe assembly and cylinders.
1. (Cars produced before March 1957 see Pl. 55, fig. 6).
On each of the outer cylinders, fit the height adjusting shims (58) and their retaining plates (57). Fit the

Carry out the same procedure as in paragraph 46.
49 To fit the clamp on the rear pipe assembly (see Pl. 55, fig. 3):
a) Put the rubber protectors (98) on the pipes, the slot towards the top. Position so that the dimension “u” =
15 to 20 mm as indicated on fig. 3.
b) Open the triple collar slightly, then put in position on the rubber protectors. Fit the tightening screw, the nut
from the left side. Tighten the nut (spring washer) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 mm box spanner
