All parts must be clean to permit an effective inspection. During assembly, it is very important that no dirt or foreign material enters the unit being assembled. Even minute particles can cause malfunction of close fitting parts such as thrust bearing, matched parts, etc.
A. Clean all metal parts thoroughly using a suitable cleaning fluid. It is recommended that parts be immersed in cleaning fluid and moved up and down slowly until all oils, lubricants, and/or foreign materials are dissolved and parts are thoroughly clean.
WARNING! Care should be exercised to avoid inhalation of vapors, exposure to the skin and creating fire hazards when using solvent type cleaners.
B. For bearings that can be removed, soak them in a suitable cleaning fluid for a minute or two, then remove bearings from cleaning fluid and strike flat against a block of wood to dislodge solidified particles of lubricant. Immerse again in cleaning fluid to flush out particles. Repeat above operation until bearings are thoroughly clean. To dry bearings, use moisture-free compressed air. Be careful to direct air stream across bearing to avoid spinning bearings that are not lubricated. DO NOT SPIN BEARINGS WHEN DRYING; bearings may be rotated slowly by hand to facilitate drying process.
For those bearings that are to be inspected in place, compressed air can be used to sufficiently clean these bearing for inspection.
C. Carefully inspect all bearing rollers, cages and cups for wear, chipping or nicks to determine condition. Do not replace a bearing cone or cup individually without replacing the mating cup or cone at the same time. After inspection, dip bearings in light weight oil and wrap in clean lintless cloth or paper to protect them until installation.
For those bearings that are to be inspected in place; inspect bearings for roughness of rotation, scoring, pitting, cracked or chipped races. If any of these defects are found, replace bearings. Also inspect the defective bearing housing and/or shaft for grooved, galled or burred conditions that indicate bearing has been turning in its housing or on its shaft.
D. It is more economical to replace oil seals, O-rings, sealing rings, gaskets and snap rings when unit is disassembled than waiting for premature failures; refer to latest Micro Fiche and/or Parts Book for replacement items. Be extremely careful when installing sealing members, to avoid cutting or scratching. Curling under of any seal lip will seriously impair its efficiency. Apply a thin coat of Permatex No. 2 to outer diameter of the oil seals to assure an oil tight fit into the retainer. Use extreme care not to get Permatex on lips of oil seals. If this happens, That portion of the seal will become brittle and allow leakage.
When replacing lip type seal rings, make sure spring loaded side is towards oil to be sealed.
