Be sure to install cap (8), using new gasket or sealer, and tighten retaining screws se- curely. Bolts attaching front wheel to hub should be tightened to 88 N.m (65 ft.-lbs.) torque. 2. TIE ROD AND TOE-IN. A single tie rod t on- nects the left and right steering arms (22 and 23— Fig. 4 or Fig. 5) which are attached to the steering spindles (16). The automotive type tie rod ends are not adjustable for wear and should be renewed if worn. Rod end threaded into right end of tie rod is used to adjust the distance between ends to establish front wheel toe-in. Recommended toe-in is 3-10 mm (V8-% in.) and should be measured between the wheel rims on centerline of axle, parallel to ground. Roi ate wheels and re-measure to be sure that wheels are not bent, giving incorrect reading. Tighten rod end jam nut after toe-in is correctly set. 3. SPINDLES, AXLE EXTENSIONS AND BUSHINGS. To remove spindle (16—Fig. 4 or Fig. | 5), first remove the wheel and hub. Disconnect rod end from steering arm (22 or 23), remove clamp screw from steering arm, then remove steering arm. Re- move key (21) and seal (if used) from top of spindle, then lower spindle out of axle (5). Clean and inspect Flg^ 5—Exploded view of front axie used on two-wheel- drlve 1020 models.

MODELS 1010 & 1020 Paragraphs 4-5 parts for wear or other damage and renew as necessary. Spindle bushings (19 and 20) should not require reaming after pressing into position in axle (5). Be sure that hole in spindle for grease fitting is clean and open before assembling. When reassembling, install thrust bearing (18) so that numbered side of bearing is facing upward. In- stall seal (17) and insert spindle through axle. Install upper seal (if so equipped) and key (21), then locate steering arm on top of spindle. Tighten steering arm retaining clamp screw to 88 N.m (65 ft.-lbs.) torque. Bolts attaching front wheel to hub should be tightened to 88 N.m (65 ft.-lbs.) torque. Balance of reassembly is the reverse of disassembly. Refer to paragraph 2 for toe-in adjustment. 4. AXLE CENTER MEMBER, PIVOT PIN AND BUSHINGS. To remove front axle assembly, first remove any front mounted equipment, guards, weights and weight frame. Raise front of tractor in such a way that it will not interfere with the removal of the axle. Remove the front wheels. Disconnect steering hoses if equipped with power steering and cover openings to prevent the entry of dirt. On all models, disconnect drag link from right steering arm. Support the axle with a suitable jack to prevent tipping while permitting the axle to be lowered and |moved safely. Remove axle pivot pin (2—Fig. 4 or Fig. r5), carefully lower the axle assembly and roll axle from under tractor. Check axle pivot bushings (4) and renew if necessary. Bushings are pressed into bore of axle and should be installed flush with bore. Split in bushing should be 45° from top of axle bore. It should not be necessary to ream bushings after installation. Reverse removal procedure when assembling. Axle end play should be 0-0.3 mm (0-0.012 in.) for 1010 models; 0-0.4 mm (0-0.016 in.) for 1020 models. Push the axle toward rear on pivot pin, then measure axle end play with a feeler gauge. Shims (3) are available in various thicknesses for adjusting end play. Make sure that pin retaining screw (1) at front is tight and that pin retaining nut at rear is snug, but not over- tightened. Install cotter pin through pin and castellated nut. Refer to paragraphs 2 and 3 for additional torque values and assembly notes. 5. FRONT SUPPORT, The front axle and radiator must be removed before unbolting the front axle support from engine. The front axle, the front support and the remainder of the tractor must each be sup- ported separately while removing, while separated and while assembling. Be sure that sufficient equipment is available before beginning. Remove any front mounted equipment, guards, weights and weight frame. Unplug lights, then remove hood and grille assembly. Remove the battery, drain cooling system, disconnect radiator hoses and remove radiator assembly. Refer to paragraph 4 and remove axle assembly. Remove the front pto, if so equipped. On all models, attach a hoist or other supporting device to front support, then remove the five retaining screws from each side and separate the front support from engine. Reattach front support to engine by reversing the removal procedure. Apply "Loctite 271" or equivalent to the ten screws attaching front support and frame to sides of engine. Complete assembly by reversing the removal procedure.

Paragraphs 6-8 MASSEY-FERGUSON STEERING SYSTEM STEERING GEAR All Models 6. A cross section drawing of the manual steering gear assembly is shown in Fig 6. Note that the steering gears are contained within a cavity in the top of the clutch housing and that the steering shaft ex- tends through the clutch housing. The steering ratio is 10:1 for all 1010 models and 13:1 for all 1020 models. Some differences will be noticed, including the number of teeth on gears (12 and 15—Fig, 7) and shaft (17) may be straight on some models. 7. R&R AND OVERHAUL. To service steering gear, it is necessary to remove the steering wheel, instrument panel cover and fuel tank. Disconnect brake and clutch rods from pedals and pedal cross Fig. &^Cross section drawing of steering gear typicai of ali modeis. Refer to Fig. 7 for exploded view. shaft, then unbolt and remove the steering wheel shaft support (24—Fig. 7). Remove clamp rings- (7) and slide boot (8) up to uncover universal joint. Re- move lower retaining ring (4) and use a punch to d rive lower pin (6) from universal joint, then separate universal joint (5) from pinion shaft (12). Notice that pins (6) are stepped and must be removed toward larger end. Remove screws attaching cover (9) to transmission housing, then remove cover, leaving pinion shaft (12) in transmission housing. Pinion shaft (12) and quadrant gear (15) can be removed together after removing retaining nut (14). Steering arm shaft (17) can be removed after splitting tractor between engine and clutch housing, then removing the engine clutch shaft. When reassembling, front wheels must be straight ahead and steering pinion (12) must be in center of teeth on quadrant gear (15). Tighten nut (14) to 59-78 N.m (43-58 ft.-lbs.) torque. If tab lockwasher is installed under nut (14), flat side of nut should be toward top and tab of washer should be bent up to lock retaining nut. Some models may be equij^ped with self-locking nut or two special nuts. Fill gear cavity half full with multi-purpose lithium ])ase grease. Nut for clamp bolt (22) retaining steering arm (21) to lower end of shaft should be tightened to 78-90 N.m (57-68 ft.-lbs.) torque. The steering arm (21) o some models is retained with a nut threaded to shaft similar to the type (14) at upper end. The larger retaining nut should be tightened to 98-117 N.m (72-87 ft.-lbs.) torque. POWER ASSIST Models So Equipped 8. Power assisted steering is available and may be installed on any model. Refer to Fig. 8 for view of flow divider valve (1), steering valve and steering assist cyhnder assembly (3), connecting hydraulic lines and attaching brackets. Most service will consist of removal, disassembly, cleaning and reassembly using new seals. Refer to Fig. 9 for exploded view of cylinder and valve unit. To remove the power steering unit, raise front of tractor so that weight is removed from the lront wheels. Disconnect hydraulic lines (2 and 8—Fig. 8), then tum steering wheel from lock to lock to dis- charge oil from steering cylinder. Disconnect steering unit from anchor bracket (4), steering arm (5) and drag link (7). To renew steering cylinder seals, remove ball joint | end from cylinder rod (41—Fig. 9).
