The first specification is given in the measuring system perceived by us to be the preferred system when servicing a particular 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. Customary system of measiurement and the Metric equivalent of 0.011 inch is 0.28 mm.

Both constant mesh and synchromesh transmissions are coupled to a three speed range transmission, which provide 9 forward and 3 reverse speeds. The constant mesh trguismission is used without live pto; the synchromesh transmission is used with live pto. t Model 275 tractors are equipped with a three forward and 1 reverse speed S3nichromesh transmission coupled to a three speed range transmission, which provides 9 forward and 3 reverse speeds. # On 275 models, capacity of the gear transmission is 6.5 L (1.7 gal.), capacity of the range transmission is 19 L (5.0 gal.), and capacity of the rear axle gear case is 3 L (0.8 gal.) for each side. 9

Paragraph 1 CASE/INTERNATIONAL FRONT AXLE SYSTEM (TWO-WHEEL DRIVE) TIRES, WHEELS AND BEARINGS All Two-Wheel-Drive Models 1, The front wheel bearings should be removed, cleaned, inspected and renewed or repacked with grease every 1000 hours of operation. % remove front wheel hub and bearings, raise and support the front axle, unbolt and remove the tire and wheel assembly, then remove cap (1—Fig. 1 or Fig. 2). On 235 and 235H models, straighten locking washer (3—Fig. 1), then remove nut (2) and lockwasher. On all except 235 and 235H niodels, reinove cotter pin, castellated nut (2—Fig. 2), and washer (3). On all models, use a suitable puller to remove t;he hub assembly from spindle axle shaft. Seal (3—Fig. 1 or Fig. 2) and inner bearing (6) will remain on spindle. Pack wheel bearings liberally with a suitable wheel bearing grease, such as Case IH 25 X HEP. Reassemble by reversing disassembly procedure. On 235 and 235H models, install new locking washer (3—Fig. 1) and tighten nut (2) to 39-58 N.m (28-43 ft.-lbs.) torque, loosen nut until the rolling torque of wheel hub (5) is 0.6-0.8 N.m (6-7 in.-lbs.), then lock position of nut with tab of locking washer (3) and install cap (1). Tighten bolts retaining front wheel to hub to 118-132 N.m (87-98 ft.-lbs.) torque. On all except 235 and 235H models, tighten castellated nut (2—Fig. 2) to 39-58 N.m (28-43 ft.-lbs.) torque, loosen nut until the rolling torque of wheel hub (5) is 0.6-0.8 N.m (6-7 in.-lbs.), then lock position of nut with cotter pin and install cap (1). Tighten bolts retaining front wheel to hub to 83-93 N.m (61-69 ft.-lbs.) torque. Rear wheel to axle hub bolts and rear axle stud nuts for 235 and 235H models should he tightened to 118-132 N.m (87-98 ft.-lhs.) torque. On 245, 255 and 275 models, the rear wheel to axle huh bolts should be tightened to 118-132 N.m (87-98 fb.-lbs.) torque and nuts securing rear wheel rim to wheel disc should he tightened to 152-172 N.m (112-127 ft.-lhs.) torque. Rear wheel disc to axle huh and rear wheel rim to wheel disc nuts should be tightened to 152-172 N.m (112-127 fb.-lbs.) torque for 265 models. On all models, lug bolt torque for all wheels should be checked after the first 10 hours of operation follow- ing installation and every 100 hours thereafter. | 25 Fig. I^Exploded view of front axie used on 235 models.

MODELS 23j>, 235H, 245, 255, 265 & 275 Paragraph 1 (Cont.) Some wheels can be reversed to change tread width on some tracto]r models, but certain wheels should only be installed one way and should not be reversed. Check with wheel or tractor manufacturer if proper installation method is not known. Refer to the follow- ing specifications for recommended inflation pres- sures. Actual air pressure should be adjusted to conform to the load on the tire and ground condition. Two-Wheel Drive 235 and 235H Front — Tire size 18 x 7.00-8-4 ply Tread type PD (G2) Max.

Rotate wheels and re-measure tc be sure that wheels are not bent, giving incorrect reading. Tighten rod end jam nut (40—Fig. 3) to 59-88 N.m (43-65 ft.-lbs.) torque after toe-in is correctly set. Bolt for clamps (38) should be tightened to 25-29 N.m (18-22 ft.lbs.) torque. Holes in tie rod tubes, pins (37) and clamps (38) are used to adjust length of tie rods when changing width of adjustable axle as outlined in paragraph 14. Two Wheel Drive 265 Model 3. On 265 models, one tie rod connects left steering arm (17—Fig. 4) to steering arm (28) and a second tie rod connects right steering arm (35). Automotive type ends are not adjustable for wear and should be renewed if worn. Holes for clamp bolts (37) in tie rods are used to adjust length of tie rods when changing adjustable axle width. It is important that both tie rods be adjusted to the same width and that width corresponds to the axle width. Refer to paragraph 14 when changing axle width. Rod ends (41) threaded into left side tie rod are used to change distance between ends and make fine adjustments to the front wheel toe-in. Tie rod end threaded into outer tube has left hand thread, per- mitting adjustment by turning tubes after loosening the rod end locknuts. Recommended toe-in is 4-8 mm (3/16-5/^6 in.) and should be measured between wheel rims on centerline of axle, parallel to ground. Rotate wheels and re-measure to be sure that wheels are not bent, giving incorrect reading. Tighten rod end jam nuts (40) to 59-88 N.m (43-65 ft.-lbs.) torque after toe-in is correctly set. Two Wheel Drive 275 Model 4. On 275 models, one tie rod connects left steering arm and spindle (10—Fig. 5) to the bellcrank (47— Fig. 6) and a second tie rod connects right steering arm. Automotive type ends are not adjustable for wear and should be renewed if worn. Rod ends (41) threaded into right side tie rod are used to adjust the distance between ends and establish front wheel toe- in. Tie rod end threaded into outer tube has left hand thread. Recommended toe-in is 4-8 mm (Vi6-^/i6 in.) and should be measured between wheel rims on centerline of axle, parallel to ground.
