If pump timing is incorrect, adjust as
follows: On 1500, 1700 and 1900 models,
remove radiator, hydraulic pump and
timing gear case. On 1710 models, re-
move pump drive gear cover plate from
timing gear case. On 1910 and 2110
models, remove radiator, hydraulic
pump and pump drive gear cover plate.
On all models, loosen cap screws at-
taching pump drive coupling (3-Fig,
123) to pump drive gear (1), then rotate
coupling counterclockwise to end of slot-
ted holes in drive gear. Make certain
that crankshaft is positioned at correct
setting as outlined above. Turn on fuel
and observe fuel fiowing from No, 1
delivery valve holder. While applying
counterclockwise pressure on pump
drive gear to remove backlash, slowly
turn pump drive coupling clockwise to
locate exact point at which fuel stops
flowing. At this point, tighten drive
coupling retaining cap screws to 25-29
N-m (19-22 ft.-lbs,) torque being careful
not to disturb timing setting.
Note that pump drive coupling to
drive gear timing marks (S-Fig. 123)
should be aligned when pump is cor-
rectly timed. If timing marks are not
present, or if they are no longer aligned,
use a chisel to mark the coupling and
gear for future timing reference.
Reinstall delivery valve and spring.
Tighten delivery valve holder to 30-35
N-m (22-26 ft.-lbs.) torque.
ENGINE SPEED ADJUSTMENT
Models 1100-1110-1200-1300
65.
To adjust engine speed, first start
engine and operate until warm. Move
throttle lever to slow idle detent posi-
tion. Engine speed should be 750-850
rpm. If low idle speed is incorrect,
loosen locknuts and turn throttle control
rod turnbuckle (3-Fig. 125) as required
until correct speed is obtained.
Move throttle control lever to max-
imum speed position and observe engine
rpm. Maximum no-load speed should be
2750-2800 rpm for 1100, 1110 and 1200
models, or 2900-2950 rpm for 1300
models. To adjust maximum speed.
loosen locknut and turn stop bolt (Fig,
125) as required until correct maximum
speed is obtained.
Models 1210-1310-1500-1510-
1700-1710-1900-1910-2110
66. To adjust engine speed, first start
engine and operate until warm. Move
throttle lever to slow idle detent posi-
tion. Engine speed should be 750-850
rpm on all models. If low idle speed is in-
correct, loosen locknuts and turn throt-
tle control rod turnbuckle (Fig, 126) as
required until correct speed is obtained.
Move throttle control lever to max-
imum speed position. Maximum no-load
speed should be as follows:

To adjust maximum speed, turn con-
trol arm stop screw (1-Fig. 127, 128 or
129) as required until correct speed is
obtained. Be sure that foot throttle
pedal does not travel below the upper
surface of foot step plate.
