SERVICE MANUAL Paragrlaph 8 To remove wheel hub (17), remove cap (21) and nut (19). Use a suitable puller to remove hub and bearings. Remove oil seal (15) and bearings (16) from hub. To remove steering bellcrank (2), I disconnect steering drag link from bellcrank. Remove clamp bolt from steering arm (I), then withdraw arm and bellcrank. Unbolt and remove bellcrank support (3 - Fig. 3C) if necessary. Inside diameter of spindle bushings (5-Fig. 6) should be 30.010-30.137 mm (1.1815-1.1865 inches). Standard clearance between spindle and bushings is 0.03-0.18 mm (0.001-0.007 inch) and wear limit is 0.3 mm (0.012 inch) clearance. Standard inside diameter of bellcrank bushings (2-Fig. 3C) is 30.010-30.137 mm (1.1815-1.1865 inches). Clearance between bellcrank and bushings should be 0.03-0.18 mm (0.001-0.007 inch) and maximum allowable clearance is 0.3 mm (0.012 inch). Use a suitable bushing driver when renewing bushings. If bushing inside diameter is deformed during installation, finish ream bushings bores so shaft can be inserted smoothly. Lubricate all parts with multi-purpose grease. Reinstall steering bellcrank (2 -Fig. 6) and steering arm (1). Position arm on ,- bellcrank shaft to remove all end play, then tighten clamp bolt to a torque of 30-39 N-m (22-29 ft.-lbs.). Tighten bellcrank support mounting cap screws to a torque of 84-92 N-m (62-68 ft.-lbs.). To reinstall wheel hub assembly and spindle, reverse the removal procedure. Tighten wheel hub retaining nut (19) to remove all play from wheel bearings, then loosen nut as necessary to install cotter pin.
