This service manuai provides specifications in both the U.S. Customary and Metric (SI)
systems of measurement. The first specification is given in the measuring system per-
ceived by us to be the preferred system when servicing a particuiar component, whiie the
second specification (given in parenthesis) is the converted measurement. For instance, a
specificaiton of "0.011 inch (0.28 mm)" would indicate that we feei the preferred measure-
ment, in this instance, is the U.S. system of measurement and the metric equivalent of
0.011 inch is 0.28 mm.

spindle bushings (19 and 22-Fig. 1),
proceed as follows: Support front of
tractor and disconnect steering arms
(17) from wheel spindles (24). Slide spin-
dle out of axle extension (21). Drive old
bushings from front axle extension and
install new ones using a piloted drift or
bushing driver. New bushings will not
require final sizing if not distorted dur-
ing installation. Renew thrust bearing
(23) if worn or rough.
2. AXLE CENTER MEMBER, PIV-
OT PIN AND BUSHINGS. To remove
axle center member (6-Fig 1), support
front of tractor, unbolt axle extensions

To reassemble, press a new bushing
into axle center member. Insert axle
center member into front support, in-
stall pivot pin and tighten pin to 300-320
ft.-lbs. (408-435 N-m). Install retainer
(2) and tighten cap screw (1) to 75 ft.-lbs.
(102 N'm). If removed, tighten radius
rod to axle extension bolts to 130-160
ft.-lbs. (176-217 N-m).
3. FRONT SUPPORT. To remove
front support, proceed as follows:
Remove engine hood, grille, lower hood
to front support bolts and unbolt
radiator from front support. Place floor
jack under front end of transmission and
take weight of tractor from front axle.
Remove front axle pivot pin as in
paragraph 2. Remove bolts retaining
front support casting to engine and
lower front support to floor. When
reinstalling, tighten front support bolts
to 180-220 ft.-lbs. (244-299 N-m).
4. DRAG LINKS AND TOE-IN.
Drag link ends are non-adjustable
automotive type and renewal procedure
is evident. Refer to Fig. 1 for manual
steering tractors and to Fig. 4 for power
steering.
Front wheel toe-in should be V4- to
V2-inch (6.35 to 12.7 mm); vary the
length of each drag link an equal amount
to obtain proper toe-in.

6. WORMSHAFT END PLAY. To
check wormshaft end play, first loosen
locknuts (1-Fig. 2) on sector shaft ad-
justing screws (8) and back screws out
two full turns. Wormshaft should turn
freely without perceptible end play.
Shims (24) are available in thicknesses of
0.0024 inch (0.060 mm) (brass), 0.005
inch (0.127 mm) (steel) and 0.010 inch
(0.254 mm) (steel); also, a 0.005 inch
(0.127 mm) thick paper gasket is
available. Install at least one paper
gasket and brass or steel shims as re-
quired. Tighten steering shaft cover re-
taining cap screws to a torque of 25
ft.-lbs. (34 N'm). Renew wormshaft
bearings as outlined in paragraph 9 if
end play is perceptible with paper
gasket, but without any metal shims in-
stalled.
After checking or adjusting worm-
shaft end play, readjust sector shaft end
play as follows:
7. SECTOR SHAFT END PLAY.
Before adjusting sector shaft end play,
be sure wormshaft is properly adjusted
as outlined in paragraphs 5 and 6, then
proceed as follows:
Turn steering wheel to mid or
straight-ahead position. With locknuts
on both sector shaft adjusting screws
loosened and adjusting screw on for-
ward sector shaft (left side) backed out
several turns, turn sector shaft ad-
justing screw (right side) in until there is
no perceptible end play in rear sector
shaft (13-Fig. 2). Tighten locknut while
holding adjusting screw. Turn adjusting
screw on left side of unit (front sector
shaft) in until there is no perceptible end
play of front sector shaft (9). Hold the
adjusting screw and tighten locknut.
Adjustment of steering gear is correct
if a pull of 1 to 2% lbs. (0.45 to 1.23 kg) is
required at outer edge of steering wheel
to turn steering gear over center posi-
tion. When adjustment of sector shafts
is correct, reconnect drag links to steer-
ing arms.
8. R&R STEERING GEAR AS-
SEMBLY. To remove steering gear
assembly proceed as follows: Disconnect
battery and remove engine hood panel.
Disconnect wiring harness plug located
forward of fuel tank and safety start
switch. Detach proofmeter cable at front
connection. Remove steering wheel and
sheet metal covers at each side of steer-

ing gear. Disconnect throttle linkage
and remove rear hood panel. Disconnect
fuel gage sender wire and all other wires
which will interfere with fuel tank
removal. Shut off fuel supply, discon-
nect fuel supply line and diesel fuel
return line from tank, then remove fuel
tank assembly. Thoroughly clean steer-
ing gear and surrounding area. Discon-
nect drag links from steering arms, then
unbolt and remove steering gear
assembly from transmission housing.
Drain lubricant from steering gear hous-
ing if unit is to be disassembled.
To reinstall steering gear, reverse
removal procedure. Refill gear housing
with Ford 134 oil.
9. OVERHAUL. Major overhaul of
steering gear unit necessitates removal
of the unit from the tractor as outlined
in paragraph 8. After removing unit,
refer to Fig. 2 and proceed as follows:
Remove steering arm retaining nuts
(14) and pull steering arms (10 and 16)
from sector shafts (9 and 13). Sector
shafts and side covers (4) can be remov-
ed as a unit after removing cover retain-
ing screws. To separate shaft and cover,
remove locknut (1) and thread adjusting
screw (8) into cover until threads clear.
Unbolt steering shaft cover (27) from
gear housing (11) and remove cover,
shaft and ball nut assembly. Do not
disassemble ball nut and steering shaft
assembly (23) as component replace-
ment parts are not available. If steering
shaft and/or ball nut are damaged,
renew the complete assembly. The need
and procedure for further disassembly
and/or overhaul is evident from inspec-
tion of the unit.
Gear housing sector shaft bushings
are not serviced separately from hous-
ing; install a new housing if bushings are
excessively worn. Bushings (5) are
renewable.
Shims (7) on adjusting screws (8) are
available in thicknesses of 0.063, 0.064,
0.066 and 0.069 inch (1.600,1.625,1.676
and 1.752 mm). When reassembling,
select a shim that will provide
0.000-0.002 inch (0.00-0.05 mm)
clearance between adjusting screw head
and slot in sector shaft.
To reassemble, insert steering shaft
and ball nut unit into gear housing with
gear teeth on ball nut forward, then in-
stall steering shaft housing (27) with
proper number of shims as outlined in
paragraph 6. Insert sector shafts, with
their adjusting screws and correct thick-
ness shims, into gear housing so sector
gear teeth and ball nut teeth are timed
as shown in Fig. 3. Place new "0" rings
(6-Fig. 2) on side covers (4) and pull
side covers into place with sector shaft
adjustment screws. Install and tighten
side cover retaining cap screws to a tor-

screw locknuts (1) while holding ad-
justing screws in proper position.
Refill gear housing with Ford 134 gear
lubricant to level of plug opening (ap-
proximately 1.3 pints [0.61 liters]).

115-125 ft.-lbs. (156-170 N-m).
POWER STEERING SYSTEM
CAUTION: Absolute cleanliness of all
parts Is of the utmost importance in the
operation and servicing of the hydraulic
power steering system. Of equal impor-
tance is the avoidance of nicks or burrs on
any of the working parts.
10. FLUID AND BLEEDING.
Recommended power steering fluid is
Ford M2C41-A oil. Maintain fluid level
at bottom of reservoir filler hole with
tractor on level ground. Fluid and filter
should be changed after each 600 hours
of operation.
The power steering system is self-
bleeding. When unit has been
disassembled, refill with new oil to full
mark on dipstick, then start engine and
cycle system several times by turning
steering wheel from lock to lock.
Recheck fiuid level and add as required.
System is fully bled when no more air
bubbles appear in reservoir as system is
being cycled.
11. CHECKING SYSTEM
PRESSURE AND FLOW. The power
steering pump assembly incorporates a
pressure relief valve and a fiow control
valve. System relief pressure should be
600-700 psi (4140-4830 kPa) while fiow
should be 2.7 gpm (10.26 liters/min.) at
1000 rpm on Models 2600, 3600 and
4100 and 2.5 gpm (9.5 liters/min.) at
1000 rpm on Models 2310, 2610, 3610
and 4110.
To check system relief pressure, in-

nect a 0-1000 psi (0-7000 kPa) gage to
fitting. With engine running at 1000
rpm and front wheels turned against
lock, gage reading should be 600-700 psi
(4140-4830 kPa).
CAUTION: When checking system relief
pressure, hold steering wheei against iock
oniy iong enough to observe gage reading;
pump may be damaged if steering wheei
is held in this position for an excessive

system pressure about 50 psi (345 kPa).
12. R&R AND OVERHAUL PUMP.
Thoroughly clean pump, lines and sur-
rounding area. Disconnect lines from
pump and allow fiuid to drain. Cap all
openings to prevent dirt from entering
pump or lines, then unbolt and remove
pump assembly from engine front plate.
When reinstalling pump, use new seal-
ing "0" ring and tighten retaining bolts
to a torque of 26 ft.-lbs. (35 N-m).
Reconnect lines, fill and bleed system as

surrounding area and disconnect pump
pressure and return lines. Remove two
cap screws securing pump to engine
front cover and lift off pump and reser-
voir as a unit. Drain reservoir and
remove through-bolt (1), reservoir (2)
and filter (3).
Relief valve cartridge (32) can now be
removed if service is indicated. For ac-
cess to shims (25), grasp seat (30) lightly
in a protected vise and unscrew body
(24). Shims (25) are available in thick-
nesses of 0.010 and 0.015 inch (0.254
and 0.381 mm). Starting with removed
shim pack, substitute shims thus varying
total pack thickness, to adjust opening
pressure. Available shims permit
thickness adjustment in increments of
0.005 inch (0.127 mm) and each 0.005
inch (0.127 mm) in shim pack thickness
will change opening pressure about 50
psi (345 kPa). If parts are renewed, cor-
rect thickness can only be determined by
trial and error, using removed shim
pack as a guide.
To disassemble pump, bend back tab
washer and remove shaft nut (23), drive
gear (22) and key (12). Mark or note
relative positions of fiange housing (18),
pump body (13) and cover (6); then
remove pump through-bolts (5). Keep
parts in their proper relative position
when disassembling pump unit. Pump
gears (10 and 11) are available in a
matched set only. Bearing blocks (9) are
available separately but should be
renewed in pairs if renewal is necessary
because of wear. Bearing blocks should
also be renewed with gear set if any
shaft or bore wear is evident.
When reassembling pump, tighten
through-bolts (5) to 15 ft.-lbs. (20 N-m)
and drive gear nut (23) to 58 ft.-lbs. (78
N-m).
13. CONTROL VALVE AND
STEERING GEAR ASSEMBLY. The
power steering system is linkage
booster type which utilizes a control
valve combined with steering shaft and
gear assembly as an integral unit. Refer
to Fig. 6 for an exploded view of
assembly. Adjustment and service infor-
mation for unit is contained in the
following paragraphs 14 through 18.
14. ADJUST STEERING GEAR.
The steering wormshaft (21-Fig. 6) is
carried in needle roller bearings (20 and
22) which require no adjustment. End
thrust of wormshaft is utilized to
operate control valve spool.
To adjust sector gears, loosen
locknuts (1) and back both adjusting
screws (8) out two full turns. Turn ad-
justing screw on rear sector shaft (13) in
until there is no perceptible backlash of
rear sector shaft gears. Tighten locknut

16. RENEW CONTROL VALVE
UPPER SEAL. If power steering fiuid
leaks from steering column housing, the
control valve upper seal (40-Fig. 6) is
leaking and can be renewed as follows:
Follow general procedures outlined in
paragraph 15, except that fuel lines do
not need to be disconnected nor does
fuel tank need to be removed.
Thoroughly clean steering gear and con-
trol valve assembly. Remove cap screws
retaining steering column (41) to steer-
ing gear and remove steering column.
