General Maintenance Procedures
scratching. Curling under of any seal lip will seriously impair its efficiency. Apply a thin coat of Loctite
#120 to outer diameter, of metal casing, on oil seals to assure an oil tight fit into retainer. Use extreme
care not to get Loctite on lips of oil seals. If this happens, that portion of the seal will become brittle
and allow leakage.
When replacing lip type seals, make sure spring loaded side is towards oil to be sealed.
5. If available, use magna-flux or similar process for checking for cracks that are not visible to the eye.
Examine teeth on al l gears carefully for wear, pitting, chipping, nicks, cracks or s cores. Replace all
gears showing cracks or spots where case hardening has worn through. Small nicks may be removed
with s uitable h one. I nspect s hafts a nd quills to m ake c ertain t hey have no t bee n s prung, be nt, or
splines twisted, and that shafts are true.
NOTE:
Spline wear i s not c onsidered detrimental except where i t af fects tightness of s plined
parts.
Inspect thrust washers for distortion, scores, burs, and w ear. Replace thrust washer if defective or
worn.
6. Inspect bores and bearing surfaces of cast parts and machined surfaces for scratches, wear, grooves
and d irt. Remove any scratches and burr s w ith crocus cloth. Remove foreign matter. R eplace any
parts that are deeply grooved or scratched which would affect their operation.
BEARING INSPECTION
The conditions of the bearing are vital to the smooth and efficient operation of the machinery. When any
component containing bearings is disassembled, always carefully examine the condition of the bearings
and all of its components for wear and damage.
Once the bearing is removed, clean all parts thoroughly using a suitable cleaning solution. If the bearing is
excessively dirty s oak t he bea ring as sembly i n a l ight s olution and m ove t he bea ring around until al l
lubricants and or foreign materials are disolved and the parts are thoroughly clean.
When dr ying bea rings, m oisture f ree c ompressed air c an be us ed. B e c areful not to d irect t he air i n a
direction which will force the bearing to dry spin while not being properly lubricated.
After the bearings have been cleaned and dri ed, carefully inspect all bearing rollers, cages and c ups for
wear, c hipping or nicks. I f the beari ng c an not be removed and is to be i nspected in pl ace, check foe
roughness of rotation, scoring, pitting, cracked or chipped races. If any of these defects are found replace
the whole bear ing assembly. NEVER replace the bearing alone without replacing the mating cup or t he
cone at the same time.
After inspection lightly coat the bearing and related parts with oil and wrap in a clean lintless cloth or paper
and protect them from moisure and other foreign materials until installation.
It is also important to inspect the bearing housing and/or shaft for grooved, galled or burred conditions that
indicate that the bearing has been turning in its housing or on its shaft.
If available, use magna-flux or similar process for checking for cracks that are not visible to the naked eye.
The following illustrations will aid in identifying and diagnosing some of the bearing related problems.
NOTE:
The illustrations wi ll only s how t apered roller bea rings, but t he principles of identifying,
diagnosing and remedying the the defects are common to all styles and types of bearings.
