At the beginning of srandard production, manufac
turing methods made ir necessary to build about
120 transmissions without an undercur at the end
of the spline on the drive shaft for the torque con-
vener. This meant that 4. 5 mm had to ground off
of the face of the coupling.
The distance A = 36 r 0.5 mm as mentioned on
page 3Y 49 musr not be applied m the shortened
coupling.
Total length of coupling = 130. 00 mm
Total length of shortened
coupling = 125.50 mm
When installed shortened end faces torque convw
ter.
When using the shortened coupling, procedures
for measuring the drive shaft are as follows.
1. Measuring without coupling:
Distance "B" must be 30 i 0.5 mm
2. Measuring with coupling:
Distance "C" mutt be 11 + 0.5 mm.
Disrallce B = 30 2 0.5 mm
Distance C = 17 t 0.5 mm
ivote
The distances 30 + 0. 5 mm and 11 + 0. 5 mm
apply to all couplings.
The protrusion can be corrected slightly with light
raps from a plastic hammer against the face of
the drive shaft.
