while steering gear is removed.
To reinstall the steering gear assem­bly, first place a new gasket on opening in transmission housing (Select-O­Speed transmission models only), then reinstall unit by reversing removal procedure. Refill gear housing with SAE 90 E.P. gear lubricant (Ford speci­fication M2C53-A).
9. OVERHAUL. Major overhaul of the steering gear unit necessitates removal of the unit from tractor as out­lined in paragraph 8. After removing unit, refer to Fig. 3 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 re­moved as a unit after removing cover retaining screws. To separate shaft and cover, remove lock nut (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 the ball nut and steering shaft assembly (23) as component replacement 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 inspection of unit.
The bushings in gear housing for the sector shafts are not serviced sepa­rately from housing; install a new housing if bushings are excessively worn. Bushings (5) in side covers (4) are renewable separately from side covers.
Shims (7) on the adjusting screws (8) are available in thicknesses of 0.063,
0.064, 0.066 and 0.069. When reassem­bling, select a shim that will provide zero to 0.002 clearance between ad-
justing screw head and slot in sector
shaft.

To rehssemble, insert the steering shaft and ball nut unit into gear housing with gear teeth on ball nut forward, then install steering shaft housing (27) with proper number of shims as outlined in paragraph 6. In­sert the sector shafts, with their ad-
justing screws and correct, thickness
shims, into gear housing so that sector gear teeth and ball nut teeth are timed as shown in Fig. 4. Place new "0" rings (6-Fig. 3) on side covers (4) and pull the side covers into place with sector shaft adjustment screws. Install and tighten the side cover retaining cap screws to a torque of 25 Ft.-Lbs. and adjust the sector shaft end play as out­lined in paragraph 7. Install new packing rings (3-Fig. 3) on adjusting screws, install flat washers (2) and tighten the adjusting screw lock nuts (1) while holding adjusting screws in proper position.
Refill gear housing with SAE 90 EP gear lubricant to level with plug (12) opening (approximately 1%4 pints). When reinstalling steering arms, tighten the retaining nuts (14) to a torque of 115-125 Ft.-Lbs.

12. R&R AND OVERHAUL PUMP. Thoroughly clean pump, lines and surrounding area. Disconnect lines from pump and allow fluid 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 sealing "0" ring and tighten retaining bolts to a torque of 23-29 Ft.-Lbs. Reconnect lines, fill and bleed system as in paragraph 10.
On early models, refer to exploded view of pump in Fig. 7 and disassemble pump as follows: Scribe an assembly mark across pump covers and body. Straighten tab on washer (34) and remove nut (35). Pull drive gear (33) from pump shaft and remove key (36). Remove the four through-bolts and separate rear cover assembly (15), plate (18), body (24) and front cover (29). Remove bearing blocks (21 and

Examine body for wear in gear running
track. If track is worn deeper than
0.0025 on inlet side, body must be re­newed. Examine pump gears for exces-
sive wear or damage on journals, faces or teeth. Runout across the gear face to tooth edge should not exceed 0.001. If
necessary, the gear journals may be
lightly polished with grade "0" emery
paper to remove wear marks. The gear
faces may be polished by sandwiching
grade "0" emery paper between gear
and face of scrap bearing block, then
rotating the gear. New gears are avail-
able in matched sets only.
When reassembling pump, install all
new seals, "0" rings and sealing rings.
On models with three shaft seals (Fig.
are installed lips
9), the two inner
seals
first and outer seal lip out to serve as a
dust seal.
Install flow control valve (3), spring (4) and plugs (1 and 13) with new "0" rings (2 and 14). Install pressure relief valve (10), spring (9) and plug (7), being sure that all shims (6) are in plug and using new "0" ring (8). Assemble pump gears to bearing blocks (use Fig. 8 as a guide, if necessary) and insert the unit into pump body. Be sure the
two bolt rings (hollow dowels) are in place in pump body, then position the front cover on body. Place the rear plate (18-Fig. 7) at rear of body and install rear cover. Tighten the four cap screws (throughbolts) to a torque of 13-
17 Ft.-Lbs. Install the pump drive gear key, drive gear, tab washer and nut. Tighten the nut to a torque of 55-60 Ft.-Lbs. and bend tab of washer against flat on nut.
On models with integral pump and
reservoir refer to Fig. 10. Clean pump

Relief valve cartridge (32) can now be removed if service is indicated. For access to shims (25), grasp seat (30) lightly in a protected vise and unscrew body (24). Shims (25) are available in thicknesses of 0.010, 0.015 and 0.060. Starting with the removed shim pack, substitute shims thus varying total pack thickness, to adjust opening pres­sure. Available shims permit thickness adjustment in increments of 0.005 and each 0.005 in shim pack thickness will change opening pressure about 35 psi. If parts are renewed, the correct thick­ness can only be determined by trial and error, using the removed shim pack as a guide.
To disassemble the pump, bend back tab washer and remove shaft nut (23), drive gear (22) and key (12). Mark or note relative positions of flange housing (18), pump body (13) and cover (6); then remove pump throughbolts (5). Keep parts in their proper relative position when disassembling pump unit. Pump gears (10 & 11) are avail­able in a matched set only. Bearing blocks (9) are available separately but should be renewed in pairs if renewal is because of wear. Bearing blocks should also be renewed with gear set if any shaft or bore wear is evident.
When reassembling the pump,
tighten through bolts (5) to a torque of
25 Ft.-Lbs. and drive gear nut (23) to a
torque of 30-40 Ft.-Lbs.

Scribe a line across steering column, valve housing and adapter to facilitate reassembly. Remove return line union (33-Fig. 12) from valve housing, dis-
card "0" ring (32) and unscrew the
check valve (34). Remove the cap screws retaining steering column and remove column from steering shaft. Carefully unstake lock nut (38) and
temporarily install steering wheel on
shaft to hold shaft while unscrewing
nut. Remove the steering wheel and
nut and position steering gear unit on
bench so that steering shaft is in hori-
zontal position. Slide spring washer (37), upper thrust bearing (36), control valve assembly (27) and lower thrust bearing (26) from steering shaft. Note: Take care that control valve spool, plungers (30) and check valves (29) do not drop out of valve housing as it is
removed from steering shaft. Unbolt and remove adapter (23) from steering gear housing.
Note which end of the control valve
spool has the identification groove (Fig.
15), then slide spool from housing.
Remove the six plungers (30-Fig. 12),
three springs (35) and the two check
valves (29), noting which hole con­tained the check valves. If any of the brass seats (28 and/or 31) for the pump pressure line and the steering cylinder lines are damaged, remove them from valve housing by threading a tap into the seat, clamping tap in vise and pulling the housing from the seat. Remove seal (40) and bushing (42) from steering column. Remove seal (24) from adapter (23).
Inspect all removed parts for damage
or undue wear and renew any not ac-
ceptable for further service. Install new "0" rings (25, 32 & 39), seals (24 and
40) and lock nut (38) when reassem­bling. To reassemble, proceed as fol­lows:
21. Install new seal (24) in adapter (23) with lip of seal up (towards control valve). Install the adapter over steering shaft and to steering gear housing with a new 0.005 thick paper gasket (19) and tighten the retaining nuts to a torque of 25 Ft.-Lbs. Place new "0" ring (25) in groove in top of adapter. Place the small race, bearing retainer and large race over steering shaft and against shoulder on shaft. Lubricate valve spool and insert in housing with identifying groove in same direction as when removed. In­sert the check valves in same bore from which they were removed and with open ends inward. Lubricate and insert the six plungers in the remaining bores with a spring between each set of plungers. Carefully place the assem­bled valve unit on steering shaft next to thrust bearing with the offset cyl­inder ports upward as shown in Fig. 16. Place large race of upper thrust bearing on shaft against valve, then install bearing retainer and small race. Place spring washer on shaft against small thrust bearing race with cup side of washer towards the race. Install a new lock nut, tighten the nut so that all end play is removed, then loosen the nut 1/6-turn and stake the nut to lo­cating slot in steering shaft as shown

27. DRAG LINK, CONNECTING ROD AND TOE-IN. Front wheel spindle arm connecting rod ends and drag link ends are of the non-adjust­able automotive type and procedure for renewing same is evident.
Toe-in should be correct for each
tread width position when connecting
rod clamp bolt is placed in corre­sponding notch of rod end assembly. If toe-in is not within limits of 0 to '/4­inch, check for bent or excessively worn parts.
On models prior to production date 8/70, length of drag link between steering gear arm and right front spindle arm should be adjusted for dif­ferent tread width positions as follows: When right front axle extension is in innermost position or extended 2
inches (one adjustment hole), drag link should be in shortest position. Then,
lengthen drag link one notch for each additional 2 inch extension of right
front axle.

If there is no perceptible end play of either the steering (worm) shaft (6-Fig. 21) or the rocker shaft (22) and a pull at outer edge of steering wheel of 1 to 2% lbs. is required to turn gear unit past mid­position (with drag link or power steering cylinder disconnected from steering arm), adjustment can be con­sidered correct. Although usually per­formed only during reassembly of gear unit, adjustments for wormshaft and rocker shaft end play can be made to correct excessive end play or turning effort. With unit removed from tractor as outlined in paragraph 32, proceed as follows:
30. WORMSHAFT END PLAY.
Remove side cover (25-Fig. 21) and
inspect condition of unit. If no obvious damage or excessive wear is noted, add or remove shims (14) and gaskets (15) so that the wormshaft turns freely, but has no perceptible end play.

Late Power Steering Models
34. Late power steering models use the integral power assist unit shown schematically in Fig. 26 and exploded in Fig. 27. A piston is built into the shaft ball nut and a pylinder machined into the gearcase housing; and the eq­tire case unit is pressurized by the steering oil. Control is by means of a rotary valve which is built into piston and ball nut unit (12) and is not avail­able separately. The, pressure passage to top of piston (P) is internal while lower end is pressurized by external flow through pressure tube (24). The piston and ball nut moves upward for a right-hand turn. Manual operation of
steering gear is made possible by a
check ball (7) located: in valve housing which recirculates oil within gear housing when pump is inoperative.
35. REMOVE AND REINSTALL. To remove the Steering gear assembly, first disconnect battery ground cable
and remove steering wheel. Remove sheet metal covers at each side of steering gear. Remove screws re­taining inf ground teAninal (left side) and rotate panel up apd out ofopening in cowl. Disconnect wiring and remove instru-

CAUTION:
cleanliness of all parts Is of the utmost Importance In the operation and servicing of the hydraulic power steering system. Of equal Importance Is the avoidance of nicks or burrs on any of the working parts.
37. Recommended power steering fluid is Ford M-2C41A oil, Maintain fluid level to full mark on dipstick on early models with separate reservoir; or bottom of filler neck on late models with integral pump and reservoir. After each 600 hours of operation, it is recommended that filter element be changed and reservoir cleaned.
The power steering system is self­bleeding. When unit has been disas­sembled, refill reservoir to full level, start and idle engine, and refill if level lowers. Cycle steering gear by turning steering wheel at least five times from lock to lock, maintaining fluid level at or near full mark. System is fully bled when no more air bubbles appear in reservoir and fluid level ceases to lower.
38. SYSTEM PRESSURE AND FLOW. Power steering system pres­sure should be 850 psi for Model 4100 with linkage booster cylinder & valve unit; and 1100 psi for late Model 4100 with integral power assist gear unit.

Early models with separate steering system reservoir were equipped with a flow control valve which maintained a regulated fluid flow of 3.5 gpm at 1000 engine rpm. On late model pumps with integral reservoir, a flow control valve is not used and normal pump flow at
1000 engine rpm is 2.74 gpm.
On all models, pressure and flow can be checked by teeing into pump pres­sure line. On early models, pressure relief valve cap plug (7-Fig. 7) is ex­ternally located and pressure can be adjusted without disassembly. On late
models with integral pump reservoir, pump must be removed for relief valve adjustment, refer to paragraph 12.

Install new seal kit by reversing removal procedure. When installing seal (9), work lips of seal into cylinder with dull pointed tool. Drive scraper into cylinder after installing snap ring (6).
42. RENEW POWER CYLINDER UNIT. With power cylinder and control valve assembly removed from tractor as outlined in paragraph 40, proceed as follows:
Cap the openings in control valve
housing (27-Fig. 37) and thoroughly
clean outside of unit. Remove the four cap screws (48) and separate cylinder from control valve unit; be careful that valve housing (27) does not slide off of valve spool and lay the control valve and ball socket unit aside. Remove spacer (18), shims (17), spring (16) and outer ball seat (14). Slide the ball stud inward from rubber boot (4) and out open end of cylinder. Remove re­maining ball seat (14), grease fitting (12) and pin (13) if pin remained with cylinder instead of staying in control valve housing. Clean and inspect the removed parts and renew any not suit­able for further use.
To install the new power cylinder and reinstall removed parts, proceed as follows: Place boot (4) over cylinder so that hole in boot is aligned with ball stud hole. Insert one ball seat (14), then insert ball stud (15), threaded end first, into open end of cylinder and extend the threaded end out through hole in
