Lift one of the front wheels of the vehicle, and
engage’ 4th or 5th gear so as to rotate the crank-
shaft,
by means of the raised wheel.
1) Vehicles /itted with n torqee ronrwrter :
Two methods are permissible to rotate the crank
shaft :
- feed the starter “iota from (I &volt battery,
or remove the protective plate under the
converter casing, and rotate the converter
using a screwdriver.
1. Remove :
spore wheel,

The stopscrew for 3rd gear can be adjusted SK the vehicle.
Carry this out as follows : Slacken locknut ( 1 ) and stopscrew (2 ). Engage 3rd gear. Bring stop-screw i 2 1 into
contact with the selector shaft. and tighten l/2 a turn, which affords a clearance of a.4 to Cl.7 mm.
Tighten lockfiut ( 1) and disengage gear.
NOTE : Adjusting the stop-screw for 2nd gear
con only be carried out with the gearbox removed
from the vehicle. To adjust it, proceed in exactly I
the same manner as for 3rd gear. Checking and adjusting the contacts :
1.
Remove cover ( 3) from the switch unit controliinq
the electro-valve. 2. Check adjustment of contact gaps :
Proceed in the same way far each of the 4 contacts.
a) Engage a gear.
WARNING In order to obtain correct opening
of a contact, the corresponding gear must be
fully engaged. otherwise the adjustment would
not be correct.
b) Check the contact gap corresponding to the
gear engaged, using a set of feeler gauges : Contact gap :
2nd
and 3rd gears 0.8 to 1.1 mm
1st and Reverse 1.3 ? 0.2 mm
c 1 Adjust the contact by slackening screw ( 5)
on the fixed contact (4 mm Allen key ) and
move this contact along its slot.
Tighten screw ( 5) from 0.35 to 0.4 doNm
( 2 l/2 to 3 ft.Ib ).
IMPORTANT : This adjustment must be carried
out with precision, otherwise, the clutch might
disengage at times without the gear lever
having been touched.
