0.3 mm.
If the distance "c" is less than 12 mm, the plate cannot be refaced any more but must be renewed.
To test the springs (use fixture 2420-T, see Pl.

NOTE - If the calibration test fixture is not available, the springs must be renewed each time the clutch is overhauled.
Hook the springs (8) on to the toggle carrier plate (2).
Put the clutch springs (6) on the bosses of the clutch driving plate (l), with one spring with green markings between
two springs with white markings, each group of three springs being fitted between two toggles.
Place a cup (7)

Tighten the nuts (3) to bring the toggles (5)
in contact with the underside of the central
pivoting lug of the fixture (see Pl. 39, fig. 3).
In these conditions (clutch in the engaged position) the dimensions obtained should be:
"a" = 37 mm between the
toggles and the clutch driving plate and
"b" = 17.8 mm between the clutch driving plate and the toggle carrier
plate (see P1.39, fig.2)

NOTE - If the fixture 1701-T is not available, in an emergency the simplified device, MR-3457-100 (see P1.40)
may be used. In order to ensure that the toggles are properly located,
operate the clutch before locking
the nuts using a ratchet press.
On this device, the dimension "c" between the top of the toggles and the face plate is 57 mm.
IMPORTANT - The clutch can only be adjusted when in the operating position. The assemblies illustrated in Pl. 39
and Pl. 40 bring the clutch into this position.
The dimensions indicated can be read only on these assemblies.
When the clutch is removed from the assembly
the toggles bear on an uneven surface and no exact measurement is possible.
