DUAL DIMENSIONS This service manual provides specifications in both the Metric (SI) and U.S. Customary systems of measurement. The first specification is given in the measuring system perceived by us to be the preferred system when servicing a particular component; the second specification (given in parentheses) is the converted measurement. For instance, a specification of "0.28 mm (0.011 inch)" would indicate that we feel the preferred measurement, in this instance, is the metric system of measurement and the U.S. system equivalent of 0.28 mm is 0.011 inch.

SERVICE MANUAL Paragraphs 4-5 4. AXLE CENTER MEMBER, PIVOT PIN AND ^BUSHINGS. Tb remove front axle assembly, raise ont of tractor in such a way that it will not interfere with the removal of the axle. A hoist may be attached to front support or special stands can be attached to sides. Removal of the axle center member may be easier if the axle extension and spindle assembly is first removed from each side; however, the complete assembly can be removed as a imit. Remove front wheels and weights, then support the axle with a suitable jack or special safety stand to prevent tipping while permitting the axle to be lowered and moved safely. Disconnect drag link from steering arm of models without hydrostatic steering. On models with hydrostatic steering, disconnect hoses from steering cylinder and cover openings to prevent entry of dirt. On all models, unbolt and remove pivot bracket (20—Fig. 4 or Fig. 5). Move axle forward until axle rear pivot is free from pivot in front support (26). Lower axle assembly and carefully roll axle away. Check axle pivot bushings and renew if necessary. Reverse removal procedure when assembling. Tighten screws retaining the axle pivot bracket (20) to 90 N.m (65 ft.-lbs.) torque. End clearance of axle center member should be 0.254 mm (0.010 inch) and is adjusted by changing thickness of shim (22). 5. FRONT SUPPORT. To remove the front support, the axle must be removed, the radiator must be removed from the support and the front support must be unbolted from the front of engine. The front axle, the front support and the remainder of the tractor must each be supported separately while removing, while separated and while assembling. Be sure that sufficient equipment is available before beginning. Remove hood, drain cooling system and disconnect radiator hoses. Disconnect air inlet hose from the front-mounted air cleaner. Remove the grille and disconnect lines from oil coolers, if so equipped. Dis- connect battery ground cable and wires to the head- lights. Unbolt radiator shell upper support bracket from the shell. Disconnect steering linkage and steering hoses that would interfere with removal of the front axle or the front support.

SERVICE MANUAL Paragraphs 7-9 FRONT-WHEEL DRIVE 7. The mechanical front-wheel drive available on these models uses a front drive axle imit manufac- tured by Carraro. There are some differences between the front-wheel drive systems used on these models, which will be referred to in the following servicing instructions. The transfer gearbox is engaged on some models by moving mechanical linkage shown in Fig. 18. On 4630 and 4830 models, engagement is controlled by an electric solenoid/hydrauhc valve that directs oil pressure to move the dog clutch (35—Fig. 20) and engage the front-wheel drive. The transfer gearbox is attached to the bottom of the rear axle center housing of all models. A drive shaft with two "U" joints connects the transfer gearbox to the front axle. TIE RODS AND TOE-IN All Models So Equipped 8. Tie rod ends may be one of several different types, but none are adjustable for wear; faulty units must be renewed. Tb check toe-in, first tum steering wheel so front heels are in straight-ahead position. Measure dis- t n c e at front and rear of front wheels from rim flange to rim fiange at hub height. Tbe-in should be 0-6 mm (O-V4 inch). Tb adjust toe-in of narrow tread models, loosen the lock nuts at each end of the tie rod, then turn the tie rod tube to set the toe-in. Tighten lock nuts at each end when adjustment is correct. Tb adjust toe-in of all other models (standard tread four-wheel drive), loosen clamp bolt (2—Fig. 6), then ^ B—View of toe-in adjustment points for four-wheel- drive models.
