Paragraphs 1-4 FORD FRONT SYSTEM AND MANUAL STEERING ALL-PURPOSE TYPE (LCG Type Front System and Manual Steering are Similar) 11 12 SPINDLE BUSHINGS 1. Refer to Fig FOl. To renew the spindle bushings, support front of tractor and disconnect the steering arms from the wheel spindles. Slide spindle and wheel assemblies out of axle extensions. Drive old busihings from axle extensions and install new ones using a piloted drift. New bushings will require no final sizing if not distorted during installation. Renew thrust bearing if unduly noisy, AXLE CENTEk MEMBER AND PIVOT PIN BUSHING 2. To remove the axle center member (18—Fig. FOl), support front of tractor, remove grille and unbolt radius rods and axle extensions from axle center member. Swing the axle extension and wheel assemblies away from tractor. On early models with non-threaded pivot pins, remove the cap screw retaining the axle pivot pin to the front end support and, using a slide hammer, remove the pivot pin. On models with threaded pivot pin, remove the cap screw (23— Fig. FOl) and locking flange (22) and unscrew the threaded pin by turning it counter-clockwise. Loosen radiator retaining nuts at bottom if necessary, to provide removal clearance and withdraw axle center member from either side of tractor. The axle pivot pin bushing (17) can be renewed at this time. Make certain that pivot pin (20) has a free fit in the bushing before reinstalling the axle center member. Install snap ring (21) on the late production threaded pin (20) on standard models, turn pin in until snap ring is tight against front support and then back pin out so that retainer (22) can be installed. On ''heavy duty" axles with hex head pivot pin, tighten pin to a torque of 200 Ft.-Lbs. On all models, tigjiten radius rod to center axle bolts (16) to a torque of 75-135 Ft.-Lbs. FRONT SUPPORT 3. To remove front support, remove grille on all models. Remove lower front panel and hood to front 14 19 20 Fig. FOl — Exploded view of All-Purpose type front oxie and rejated ports. Optionol "heovy duty" front axle is similarly constructed except that pivot pin (20) has hex heod, snop ring (21) is not used and retainer (22) has hex opening for pivot pin head. A flot washer (not shown) is used on cop screw (23) between retainer (22) and front support (19) on "heavy duty" assemblies to prevent retainer from being cocked. Early production pivot pin was not threaded and pivot pin (20) and retainer (22) were integral welded assembly. 1. Spindle (R.H.) 2. Lower spindle bushing 3. Woodruff key 4. Thrust bearing 5.

To check wormshaft end play, first loosen the lock nuts (1—Fig. FO2) on the sector shaft adjusting screws (8) and back the screws out at least two full turns. If the end play of the wormshaft (steering wheel shaft) is not within the desired limits of 0,006- 0.010, adjust the end play by varying the thickness of the shim stack (18) between the steering shaft tube and the steering gear housing. Shims are available in thickneses of 0.002, 0.005, 0.010 and 0.030. Ford recommends a minimum shim stack installation of not less than three 0.002 shims or not less than two 0.005 shims. Tighten the steering sJiaft cover retaining cap screws to a torque of 25-30 Ft.-Lbs. Renew wormshaft bearings as outlined in paragraph 10 if end play is over 0.010 with minimum recom- 7.

Only the heavy duty sector gears will be available for servicing all modeb when current stocks of standard sector gears are exhausted. If necessary to renew a standard sector gear using a heavy duty gear, both sector gears must be renewed. Gears may be identified as follows: Standard sector gear (9A) has 7 full teeth; heavy duty sector gear {9A) has 5 full teeth. Standard sector gear (9) has 6 full teeth and 3 rack teeth; heavy duty sector gear (9) has 4 full teeth and 3 rack teeth. Service procedures remain unchanged. 5. ADJUSTMENT. To adjust t;he steering gear, first make certain that gear housing is properly filled with lubricant, discnonect both drag links from steering gear arms to remove load from the gear unit and proceed mended shim stack thickness. After checking or adjusting wormshaft end play, readjust sector shaft end play as follows: 7. SECTOR SHAFT END PLAY. Before adjusting sector shaft end play, be sure that wormshaft end play is correctly adjusted as outlined in paragraphs 5 and 6, then proceed as follows: Turn the steering wheel to the mid or straight ahead position. With the lock nuts on both sector shaft adjusting screws loosened aijd the adjusting screw on the right hand side (as viewed from rear of tractor) backed out several turns, turn the adjusting screw on left side of steering housing in (clockwise) until there is no perceptible end play in the sector shaft to which the right steering arm is attached. While hold- ing the adjusting screw in this position, tighten the lock nut. Then, turn the adjusting screw on right side of housing in until there is no perceptible end play in the sector shaft to which the left steering arm is attached, hold the adjusting screw in this position and tighten the lock nut. Reconnect the drag links to the steering arms. 8. REMOVE AND REINSTALL. To remove the steering gear and housing assembly, first remove steering wheel, then withdraw the spring, felt packing and spring seat from top of steering column. On **Select-O-Speed" transmission models, remove PTO control and gear selector as outlined in paragraph 234. Remove hood. Dis- connect throttle rod from bell crank and unbolt throttle rod bracket from transmission. Disconnect the Proof- Meter cable, ammeter lead wire and oil pressure gage line at instrument panel. Disconnect the battery ground cable from steering gear housing and wires from junction block on steering column. Remove the generator regulator from bracket on steering column and disconnect the temperature gage wire from fuel tank frame. Unbolt instrument panel, slide the panel over top of steering column and lay it on top of fuel tank. Unbolt battery carrier from steering gear housing. Discon- nect head light switch and ignition switch from the hood rear lower panel; then, unbolt and remove the hood rear lower panel from tractor. Unclip tail light wire from steering gear housing and disconnect drag links from pitman arms. Remove the cap screws retaining steering gear housing to transmission case and lift the steering gear assembly from tractor. NOTE: On *'Select-O-Speed"

Paragraphs 9-13 transmission models, a gasket is used between steering gear and transmission housings. Gasket should be left in place or opening in transmission covered when steering gear housing is removed. Be sure that gasket is in good condition before reinstalling steering gear assembly. 9. OVERHAUL. Major overhaul of the steering gear unit necessitates the removal of the unit from tractor as outlined in paragraph 8. Remove the pitman arm retaining nuts and pull pitman arms from sector shafts. Un- bolt the sector shaft side covers and remove the adjusting screw lock nuts (1—Fig. FO2), Using a screwdriver, turn the adjusting screws in and remove the side covers and sector shafts. Unbolt steering housing upper cover from housing 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 the steering shaft and/or ball nut are damaged, renew the complete assembly. The need and procedure for further disassembly and/or overhaul is self-evident. The renewable bushings in steering gear covers have a bore diameter of 1.1255-1.1260; bushings in housing have a bore diameter of 1.245-1.250. S,hims (7) on the adjusting screws (8) are available in thicknesses of 0.063, 0.065, 0.067 and 0.069. When reassembling, use a shim that will provide zero to 0.002 clearance between adjusting screw head and slot in sector shafts. When reassembling, center the ball nut on wormshaft and insert shaft in housing. Bolt the housing upper cover assembly in position, using the necessary number of shims (18) to provide an end play of 0.006-0.010 of wormshaft in bearing. Minimum shim stack should be three 0.002 shims or two 0.005 shims. If end play is more than 0.010 with minimum recommended thickness of shims, renew the worm- FORD shaft bearings. Shims (18) are available in thicknesses of 0.002, 0.005, 0.010 and 0.030. Tighten the cover cap screws to a torque of 25-30 Ft.- Lbs. Assemble the sectors and their adjusting screws (8) to their covers. Hold the left sector shaft (the one with the greater number of teeth) and side cover assembly with the block tooth up, and install the sector so that middle tooth on sector meshes with middle groove on the ball nut rack. Install the right sector shaft, meshing the fourth tooth with the fourth groove of the left sector shaft. Tighten the side cover cap screws to a torque of 25-30 Ft.-Lbs. and install the adjusting screw lock nuts. Turn steering gear to its mid or straight ahead position and install pitman arms. When installation is complete, fill gear housing with lubricant and adjust the sector shaft end play as outlined in paragraph 7. Reconnect the drag link.

On models with power assist steering, the installed length of the drag link should be adjusted to 46^3^ to 46^ inches, measured between centers of sockets at each end of the drag link. The offset (elbow) in the drag link must be towards the front end of the tractor, and point 15 to 20 degrees below horizontal and away from the engine. If tractor is equipped with loader, check clearance between drag link and left-hand cylinder on loader in all positions of front axle, loader and drag link. If interference exists, loosen lock nuts at each end of drag link, rotate sleeve slightly to provide clearance and re- tighten lock nuts. 18. The tie rod ends (and drag link ends on power-assist steering models) are of the non-adjustable automotive type. Renewal procedure is evident. Fig. FO9 — Roise front of Heavy Duty industrioi tractor with a hoist and roil front axie and wheeis assembly forward away from tractor. Adjust the tie rod to provide V4 to V^-inch toe-in by loosening the clamp on each end and rotating the tube until the toe-in is correct. Refer to paragraph 17 for adjustment of drag link. FRONT SYSTEM AND STEERING GEAR, ROW CROP PEDESTAL AND COMPONENTS Early Series 700-900 19. REMOVE AND REINSTALL. To remove the pedestal, proceed as follows: Provide support for the front of the tractor and drain the radiator. Remove the bolts retaining hood to pedestal and the nuts from the radiator retaining studs. Disconnect drag link from front steering arm. Support pedestal in a suitable manner, unbolt pedestal from engine and side rails and move the pedestal and wheels assembly away from the tractor. The radiator will be supported by the radiator hoses and the fan after the pedestal is removed. See Fig. FOIO. Note: It may be necessary to loosen the generator adjusting bracket and the lower radiator hose to gain access to one of the pedestal lower retaining bolts. Replacement pedestals are factory fitted with bushings, bearing cup and seals. 20. OVERHAUL. Normal overhaul of the pedestal can be accomplished without removing the pedestal from the tractor as follows: Remove grille, drain the pedestal oil reservoir and remove the reservoir cover. Raise the front of the tractor until the bottom of the pedestal is ap- proximately 18 inches from the floor and remove the front wheel and hub assemblies. Remove the front steering arm (4—Fig. FOIO), thrust cap (5) and shim stack being careful not to damage or lose the shims. Support the vertical spindle (18), remove nut from top of spindle shaft and bump the vertical spindle down and out of pedestal. Turn steering sector arm shaft (7) until the bevel gears un- mesh and withdraw gear (11). Pull steering sector arm shaft (7) and gear unit out through top opening in pedestal. The need and procedure for further disassembly is self-evident. Bushings (1) for sector arm shaft and bushing (10) at top of spindle are renewable and require no final sizing if carefully installed using a suitable piloted driver.
