Refer to Fig. 162 for an exploded
view of starting motor and solenoid. Pin-
ion clearance (C-Fig. 159) should be
0.2-1.5 mm (0.008-0.060 inch) with
solenoid engaged. To check clearance,
disconnect and^ insulate field wire from
solenoid terminal. Engage solenoid by
attaching jumper cables (1, 2 and 3) to
locations indicated. Push pinion back to
remove slack and use a feeler gage to
measure clearance between pinion and
stop collar. Clearance can be adjusted by
adding or removing shims

ADJUSTMENT
All Models
100.
Clutch pedal free travel should
be 20 to 30 mm (% to
1-1/16
inches).
Free travel is measured at pedal pad as
indicated in Fig, 165 or 166. To adjust,
disconnect clevis (2) from bellcrank and
lengthen or shorten rod (1) as required
to obtain recommended free travel.
On models equipped with dual clutch,
adjustment of pto clutch release bolts
can be checked after removing rubber
cover from side of clutch housing.
Clearance between head of bolts
(3-Fig. 167) and pto pressure plate (4)
should be between
1.6-1.8
mm
(0.063-0.070 inch) for 1500, 1700, and
1900 models or 0.9-1.0 mm (0,035-0.039
inch) for 1310, 1510, 1710, 1910 and
2110 models.
Check adjustment of safety start
switch (3-Fig. 165), if so equipped, as
outlined in paragraph 93 after clutch
linkage is adjusted.
