A typical front wheel spindle, wheel hub and bearing assembly is shown in Fig. 1 or 4. The tapered inner and outer roller bearings are the same size on some models. however if bearings are to be reused they should be reinstalled with mating bearing cones and cups togeth- er. Note that lip of oil seal is installed away from inner bearing. It is recommended that bearings be lubricated with a pressure gun until grease is forced out past seal lip after each 60 hours of operation. When adjusting wheel bearings. tighten nut to provide 0.003 inch end play to 0.002 inch preload and install cotter pin. Model8S5N 2. The Model 885N front wheel spindle. wheel hub and bearing assembly shown in Fig. 2 is similar to other models except that bearing adjustment is controlled by shims (5). Vary shims as required to provide 0.003 inch end play to 0.002 inch preload and secore heads of cap screws with tabs of leek plate (3). Shims (5) are available in thicknesses of 0.005, 0.010 and 0.030 inch. SPINDLES All Models 3. R&R SPINDLES. To remove spindle. support front of tractor and remove wheel. Remove cap screw and washer which retains steering arm and remove steering arm from spindle. NOTE: If steering arm Is tight on spindle, loosen cap screw about two or three turns and rap head of cap screw sharply to loosen steering arm from spindle. Withdraw spindle and remove upper "0" ring and thrust washer or thrust bearing and lower "0" ring. Reinm stall by reversing removal procedure and tighten steering arm retaining cap screw to 120 ft.-Ibs. torque. 4. SPINDLE BUSIIINGS.

TIE-RODS AND TOE-IN All Models 5. Toe-in of front wheels should be l/16-l/S-inch and can be adjusted by lengthening or shortening the tie-rod. Adjust tie-rod ends an equal amount. Tie-rod ends are available as a unit only. AXLE MAIN MEMBER AND PIVOT PIN All Models 6. On early 995 (prior ser. no. 934315) \.ractors it is necessary to split tractor between front support and main frame using the following procedure: Remove hood and drain cooling system. Disconnect radiator hoses. battery cable and air cleaner hose at rear side of radiator. Disconnect drag link (manual steering) or steering ram (power steering) from steering arm. Support traetor under main frame and attach a hoist to Iront unit. Unbolt Iront support Irom main frame and roll assembly away from tractor. Loosen the pivot pin retaining cap screw about five turns, rap on head of cap screw to dislodge threaded insert, then remove cap screw and threaded insert. Attach a slide hammer, pull pivot pin rearward from front support and front axle. then raise front support until it clears axle assembly. Remove the thrust washers and sealing "0" rings. The two rear bushings (B-Fig. 5) may be removed with suitable driver. To remove the two front bushings from blind hole. use a cape chisel and pliers. Drive new forward front bushing into blind hole until it bottoms or is forward of lubrication hole. then drive second front bushing in flush with support casting. Drive rear bushings into sup· port from each side until bushings are flush with support casting. Bushings are pre·sized and should not require reaming if carefully installed. Be sure pivot pin is a free fit in bushings before reinstalling front axle to front support. The axle front to rear float in front support should be 0.002-0.014 inch. Renew pivot thrust washers if front to rear float is excessive. When rejoining front support to main frame, tighten bolts to 45 ft.-lbs. torque. 6 Fig. 3-Exploded ~,.w of front Ix'e 8ssemb'y used on Models 1210. 1212, 1410 and 1412 equipped with transverse mounted powe, Iteerlng cylinder.

Paragraphs 13·15 the right hand axle shaft is shorter than the left hand axle shaft. 13. REMOVE AND REINSTALL. To remOVe final drive, jack up affected side of axle, remove wheel and tire and drain housing. Disconnect tie·rod from carrier and if left band unit is involved. also disconnect the power' steering ram from carrier. Remove cover plate (9-Fig. 6). Remove cap screw and lock (21.Fig. 7) and adjusting nut (20), then remove king pin (22) using tapped hole in bottom of king pin. Withdraw final drive, unit from axle housing and take care that axle shaft does not damage bearing (15·Fig. 8) located in axle housing. NOTE: If necessary. s- tool for removal at king pin can I)e fabricated using the dimensions shown in, Fig. 9. The values shown are in millimeters. Also note when using removar tool, removal of king pin will be a three-step operation. Bearing (19-Fig. 7), lower washer (18), "0" ring (17) and seal (16) can now be removed. DO NOT remove upper beariDg (11) unless it is to be renewed or other new !inal drive parts are being insWIed. If necessary, axle hearing (15·Fig. 8) can be pulled from axle housing after removing oil seal (17) and snap ring (16). 14. The final drive assembly is installed by reversing removal proce· dure. however if a new axle housing. final drive housing (carrier), king pin upper bearing or spacer is installed, the mounting dimensions of axle hOlls· ing and final drive honsing must be ehecked and reset, if necessary. to insure that axle halves are in align· ment. During machining of the final drive housing (carrier) and axle housing, plus or minus deviations can occQr and are stamped on final drive carrier and axle housing as shown in Fig. 10. The reference dimension for final drive housing (carrier) is 107.00mm and reference dimension for axle housing is 72.90 mm. Plus deviations are added to reference dimensions and minus deviations are subtracted from reference dimensions. If there is no deviation during machining the deviation stamp· ing will be "0" (zero). Also needed to calculate the required thickness of spacer is the overall thickness of king pin upper bearing assembly. Standard thickness of bearing is 25.60 mm but it should he measured as deviations can occur. Refer to the following paragraph for an example to calculate spacer thickness. 8 15. Assume the final drive housing (carrier) is stamped with + 0.18 devia- tiOD, the axle housing with - 0.12 deviation and upper bearing measures 25.60 mm.

The axle operates with a 0.25 mm preload and preload is con· trolled by spacer (S-Fig. 8). Spacer is available in thicknesses from 1.60 mm through 2.70 mm in increments of 0.05 mID. Determine correct spacer thi~ess as follows: 1~ Measure from inner race of bear· Fig. 12-Exploded "ltw 01 "ont d,I", dln,,,,,u., and dr'". sh.r, and In Mod., 1210 'our wh"' drl". t,.c>- to". 1.
