Bearings
Anti-Friction Bearings
When an anti-friction bearing is removed, cover it to keep out dirt and abrasives. Wash the bearings in nonflammable cleaning solution and allow them to drain dry. The bearings may be dried with compressed air, but DO NOT SPIN THE BEARING. Discard the bearings if the races and balls or rollers are pitted, scored or burned. If the bearing is serviceable, coat it with oil and wrap it in clean paper. DO NOT unwrap new bearings until time of installation.The life of an anti-friction bearing will be shortened if not properly lubricated.Double Row, Tapered Roller
Double row, tapered roller bearings are precision fit during manufacture and the components are not interchangeable. The cups, cones and spacers are usually etched with the same serial number and letter designator. If no letter designators are found, wire the components together to assure correct installation. Reusable bearing components should be installed in their original positions.Heating Bearings
Bearings which require expansion for installation should be heated in oil not to exceed 121°C (250°F). When more than one part is heated to aid in assembly, they must be allowed to cool and then pressed together again. Parts often separate as they cool and shrink.Installation
Lubricate new or used bearings before installation. Bearings that are to be preloaded must have a film of oil over the entire assembly to obtain accurate preloading. When installing a bearing, spacer or washer against a shoulder on a shaft, be sure the chamfered side is toward the shoulder. When pressing bearings into a retainer or bore, apply pressure to the outer race. If the bearing is pressed on the shaft, apply pressure on the inner race.Preload
Preload is an initial force placed on the bearing at the time of assembly.Determine preload or end clearance form the Specifications Section of this Service Manual. Care should be exercised in applying preload. Misapplication of preload to bearings requiring end clearance can result in bearing failure.Sleeve Bearings
DO NOT INSTALL SLEEVE BEARINGS WITH A HAMMER. Use a press, if possible and apply the pressure directly in line with the bore. If it is necessary to drive on a bearing, use a driver or a bar with a smooth flat end. If a sleeve bearing has an oil hole, align it with the oil hole in the mating part.
