Axle is carrie r on tapered roller bearings which can be adjusted to provide a noticeable drag, by shims located between each bearing cone and fork bearing block as sh own. S hi ms are ava il a bl e in thicknesses of 0. 003 and 0.005. STEERING KNUCKLES Series 430-530, Non-Adjustable Axle 3. Fig. 3 shows a n exploded view of a non-adjustab le front axle of the gene ral t ype use d. To remo ve the stee r ing knuckles, support front of tractor and remove wheel and hub assemblies. Dis· con nect tie-rod and dra g link a nd reo move plugs (I 7). Remove screws (22) and bump king pins (16) from axle and knu ckles . Ream king pin bushings (IS). after installa ti on, to provide a c:Iearance of 0.001·0. 003 for the king pin. When reassembling, renew thrust bearings (2 1) if the ir condition is ques- tionable. Series 630, Non-Ad justable Front Axle 3A. The hea vy-duty. non-adjustable fr ont axle used on 630 Series tr actors is s hown in Fi g. 4. Knu ck les (1 4) are carr ied in Torrington needle bearings (22). Before removing old bearings note J. I. Case their exact poSition and insta ll new ones in the same location. Instal! upper bearing using Case arbor A· 8354 or equivalent . Ins tall low er bearing, using Case ar bo r A-835 1 or equivalent. Wh en installing the steering arms, tighten the retaining nut to remove all spindle end play without ca u sing binding. All Models, Adjustable Axle 4. Refer to Fig. 5 or Fig. 6 for an ex ploded view of the adjustable axle used. To remove the stee ri ng knuckles. su pp ort front of tractor , remove stee rin g arm ( 8) and wit h draw knu ckle. Bushings (10) are pre.sized to provide a clearance of 0.003-0.007 for the knuckles. Be s ure to renew thru st bearings (J2) if their condition is ques- tionable. When reassembling, vary the number of 0.010 thick shims (9) to remove all spindle end play without ca using any bindin g. TIE RODS AND DRAG LINK All Models So Equipped 5. Tie-rod ends are of the renewable automotive type. Drag link ends on non·adjustable axle types are int egral with the drag link. On adjustable axle models. adjust the lengt h of each tie rod an equal amount to provide a toe-in of \oIiI -3/ 16·inch . On utility models. loosen the clamp bo lts and t urn the tie rod tube either way as required. to obtain the recommended \oIiI -31l6-inch toe·in . F/g . 3~.plodld . /,l1li' of non-.dJu." bI.
