DUAL DIMENSIONS i • ' . w ' , ~ ' • This service manual provides specifications in both U~S. C~?tomary and Metric (SI) systems of measurement. The first specific1=ltion is given in the m'easuring system p~rceived by us to be the pref~rred system when servicing a particul'~r component, while the second specification (given in parenthesis) is the converted measurement. For instance, a specification of 0.011 inch (0.28 mm) would indicate that we feel the preferred measurement in this instance is the U.S. C~stomary system of m'easurement and the Metric equivalent of 0.011 inch is 6.28 mm. . . , . ....

Paragraphs 1-2 MASSEY-FERGUSON FRONT AXLE SYSTEM (TWO-WHEEL DRIVE) FRONT AXLE ASSEMBLY AND STEERING LINKAGE Two-Wheel-Drive Models 1. WHEELS AND BEARINGS. To remove front wheel hub and bearings, raise and support the front axle extension, then unbolt and remove the tire and wheel assembly. Remove cap (2 or 3-Fig. 4), cotter pin (4), castellated nut (5), washer and outer bearing cone (7). Slide the hub assembly from spindle axle shaft. Remove dust shield (12), seal (9) and inner bearing cone (11). Drive bearing cups (8 and 10) from hub if renewal is required. Pack wheel bearings lib- erally with a multi-purpose lithium based grease. Reassemble by reversing disassembly procedure. Tighten castellated nut (5) to a torque of 80 N.m (60 ft.-Ibs.), then back nut off to the nearest hole and install cotter pin (4). Be sure to install cap (2 or 3) securely. 2. TRACK ROD AND TOE-IN. All models are equipped with hydrostatic steering. On 340-360 models, a single track rod connects the left and right steering arms which are attached to the steering spindles. On 399 models, the two track rods are Fig. 4-Exploded view of wheel hub typical of two-wheel- drive models. 2. Hub cap 3. Hub cap 4. Cotter pin 5. Castellated nut and tang washer 6. Hub 7. Outer bearing cone 12 8. Outer bearing cup 9. Seal 10. Inner bearing cup 11. Inner bearing cone 12. Dust shield 17. Wheel retaining screws attached to each end of the hydrostatic steering rod, which is located between the steering arms. The track rod of all models assures that both left and right wheels turn in unison and the distance between ends of track rod establishes front wheel toe-in. Ends of track rod are automotive type and should be renewed if wear is excessive. The procedure for removing and installing ends is self-evident. Recom- mended toe-in is 0-5 mm (0-3;16 inch) for all models. Toe-in should be measured between the wheel rims on center line of axle, parallel to ground. Rotate wheels and remeasure to be sure that wheels are not bent giving incorrect reading. Distance between front wheels is adjustable to seven different widths by relocating axle extensions and changing length of track rod using the pre-exist- ing attachment holes. On 340-360 models, axle extension and hydrostatic steering cylinder bracket retaining screws (I-Fig. 5) should be tightened to 180-230 N.m (135-170 ft.-Ibs.) torque. Tighten track setting screw (2) to 45-55 N.m (33-40 ft.-Ibs.) torque before tightening locknut. Note that spacers are used on the outer screws between steering cylinder brackets and axle extensions when axle width is at the four widest settings. To make small toe-in adjustments, remove track adjusting screw (2) from left end of track rod, loosen rod end clamp bolt on right end, then turn center section of track rod until toe-in is correct. Reinstall track adjusting screw (2) and tighten rod end clamp bolt to 45-55 N.m (33-41 ft.-Ibs.) torque. Fig. 5-View of axle left end typical of 340-360 models. Track adjusting screw and lock nut (2) and cylinder bracket and axle extension screws (1) must be properly installed and tightened.

MODELS 340, 350, 355, 360 & 399 Fig. 6-View of axle left end typical of type used on 399 models. Right side is equipped with a similar track rod, adjusting bolt (2) and rod end. Rod end may be locked with clamp bolt (3) as shown or jam nut. On 399 models, axle extension retaining screws (I-Fig. 6) should be tightened to 340-450 N.m (250- 330 ft.-Ibs.) torque. Tighten track setting bolt (2) to 120-160 N.m (90-120 ft.-Ibs.). To make small toe-in adjustments, remove track adjusting bolt (2), loosen rod end clamp bolt (3) or jam nut, then turn track rod until toe-in is correct. Reinstall track adjusting bolt (2) and tighten to 120-160 N.m (90-120 ft.-Ibs.) torque. Tighten rod end clamp bolt (3) to 45 N.m (33 ft.-Ibs.) torque or jam nut to 160-200 N.m (120-130 Fig. 7-Exploded view of front axle typical of two-wheel-drive 340-360 models. 1. Steering arm 2.

SPINDLES, AXLE EXTENSIONS AND BUSHINGS. To remove spindle (12-Fig. 7 or Fig. 8), first remove the wheel and hub. Disconnect rod end (2) from steering arm (1), remove clamp screw (13) from steering arm, then remove steering arm. Remove key (14) and seal (20) from top of spindle, then lower spindle out of axle extension (19). Remove thrust bearing (11) from spindle. Clean and inspect parts for wear or other damage and renew as neces- sary. Each axle extension (19) is equipped with two spindle bushings that must be reamed after pressing into position. Clean all metal particles from bore and be sure that hole for grease fitting is clean and open before assembling. When reassembling, install thrust bearing (11) on spindle so that numbered side of bearing is facing upward and insert spindle through axle extension. Install seal (20) and key (14) then locate steering arm on top of spindle. Tighten steering arm retaining clamping screw to a torque of 125-165 N.m (94-122 ft.-Ibs.) for 340-360 models; 280-370 N.m (207-273 ft.-Ibs.) torque for 399 models. Refer to paragraph 2 for track and toe-in adjustment and other recom- mended torques. Balance of reassembly is the reverse of disassembly. 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 13
