OPERATION No. ID. 3 12 - 3 :
Overhauling a clutch assembly ID 19
PARTICULAR POINTS
Dismantling.
Mark the position
of
the clutch driving plate on the toggle carrier plate.
Assembly.
Reface the clutch driving plate by grinding, if this is not possible a facing tool may
be used.
Minimum thickness after rectification
L 12
mm;
replace
the driving plate if the thickness is less than I2 mm.
On assembly, compensate
for
this loss
of
thickness by fitting steel washers to the springs, equal in thickness to the amount removed from the clutch
driving plate. (original thickness = 13 0
-0.3
mm
Spring characteristics:
6 springs marked white, length 29' 7 mm, under load
of 52
+ 3.5
kg.

3 springs marked green, length 29.7 mm, under a load
of
64 + z. 5 kg.
When assembling,$t
one
spring with green markings between two springs with white markings and each group
of
three springs
between
two toggles.
The clutch can only be adjusted when in the operating position. Use the$xture (170/-T, see PI.39 or MR.3457-100, see Pl.40); dimension "a"
= 37 mm between the toggle
and
the driving plate
and
"b" =: 17.8 mm between the driving plate and the toggle carrier plate (see Pl.39, fig. 2).
TOOLS
DISMANTLING (see Pl .38)
Using a centre punch, mark the position of the clutch driving plate on the toggle carrier plate (2). With a saw blade
remove the metal of the nuts (3) from the slots of the screws (4).
Remove the toggles (5) by unscrewing the adjusting nuts (3) . . . . . . . . . . . . . . . . . . . . . . . . . . . .'i . . . . . . . . . . . . . . . . . . . . . . . .
Withdraw the clutch driving plate (l), the springs (6) and the spring cups (7).
Remove the toggles (5) and the toggle springs (8).
Clean the parts.
ASSEMBLY (see Pl. 38)
Reface the clutch driving plate (1) on a lathe (it is preferable to carry out this operation with a grinding wheel, but
in an
emergency
a facing tool can be used).
NOTE - Each time the surface of the clutch driving plate is refaced,
there is a resultant decrease in the pressure
exerted
on
the clutch disc. This reduction in pressure must be compensated by fitting washers cut from sheet
metal equal in thickness to the amount of metal removed during refacing.
