transport until scribed lines are 3.2-3.9
mm (1/8-5/32 inch) apart. Adjust
transport stop to hold control lever at
this point on quadrant. If stop adjust
ment is impossible, lift cover internal
linkage may be incorrectly adjusted,
damaged or binding Check linkage
through right side opening. Also check
relief valve operation through this
opening.
On pressure control models, move in
ner quadrant lever into "CONSTANT
PUMPING" range at "PRESSURE"
control side of
transport
stop, then scribe
a line CL-Fig. 183) across lift
arm
and
lift cover hub. Move inner quadrant
lever
to
"POSITION" s1de of transport
stop, firmly against stop pin. Measure
distance between the scribed lines.
If
not
within 3.2-3.9
mm
(1/8-5/32 inch), loosen
control quadrant mounting bolts and
m
o
v
e only the inner quadrant to correct
the setting.
198. DRAFT CONTROL. Adjust draft
control
as
follows: Disconnect top link,
but leave weight or implement attached
to
lower links. Run engine at idle speed.
Move inner quadrant lever to "TRANS
PORT" position and move draft control
l
ever downward until weight just begins
to fall. Position draft lever so weight re·
mains suspended in approximately mid
position, then note location of lever. If

and relocate quadrant until sector
marks are correctly located. Tighten re
taining screws, then recheck adjust
ment.
199. PRESSURE CONTROL. To ad
just pressure control, proceed
as
follows:
Implement or weight must be attached
to lift links and pressure gage connected
to lift cover as shown in Fig. 176. Run
engine at low speed and move draft. con
trol lever fully "UP." Move inner
quadrant lever forward as far as possi
ble, then move lever rearward into
"CONSTANT PUMPING" and note
pressure gage reading.
If pressure is not within 17240-17930
kPa (2500-2600 psi), move inner lever
fully down and acljust pressure control
valve tube (accessible through response
cover opening). Turn tube clockwise to
increase, or counterclockwise to decrease
pressure to recommended setting.
When pressure is within limits, lurn
pressure control acijusting screw (5-Fig.
181) clockwise until vertical lever
Ill
begins to pulsate, then turn sere\\
counterclockwise until pulsating stops
and pressure does not fluctuate more
than 700 kPa (100 psi).

(R)
down,
then retighten set screw to hold
rod m
place Move the response control lever
to "FAST" position, then remstall
response side cover (without outer cover)
onto housing. Move response control
lever to place it about 6.4 mm (1/4 inch)
from "SLOW" position. Remove access
plug from side cover. Insert a wrench
through access opemng and loosen set
screw to allow plunger to release and
contact response lever shaft. Retighten
set screw. Install access plug and outer
cover.
Fill housing
to
full mark on dipstick
with recommended oil. Start engine and
raise and lower lift links several times
using draft control lever to purge air
from dashpot. Check for proper opera·
lion of hitch.

MASTER
CONTROL
SPRING.
To acljust master control
spring <7-Fig. 185), disconnect upper
link control beam from spring head (10).
Position draft control lever fully down.
Check for end play in spring by pulling
and pushing on spring head. If end play
IS
present, loosen set screw (3) in s1de of
lift housing and pull back rubber boot
(9) to expose adjusting nut (8). Turn ad
JUstmg nut into or out. of lift cover until
end play is just eliminated.
NOTE: End
play will be
present II

Justlng nut Is either too
loose or
too tight.
If end play cannot be eliminated by
turning adJustmg nut, it will be
necessary to remove control spring
assembly and check internal acijustment
of spring as follows: Unscrew acijust.ing
nul and withdraw spring assembly from
