GENERAL INFORMATION
Cleaning
Clean all metal parts except bearings, in mineral
spirits or by steam cleaning. Do not use caustic
soda for steam cleaning. After cleaning dry and put
oil on all parts. Clean oil passages with compressed
air. Clean bearings in kerosene, dry the bearings
completely and put oil on the bearings.
Inspection
Check all parts when the parts are disassembled.
Replace all parts that have wear or damage. Small
scoring or grooves can be removed with a hone or
crocus cloth. Complete visual inspection for
indications of wear, pitting and the replacement of
parts necessary will prevent early failures.
Bearings
Check bearings for easy action. If bearings have a
loose fit or rough action replace the bearing. Wash
bearings with a good solvent or kerosene and
permit to air dry. DO NOT DRY BEARINGS WITH
COMPRESSED AIR.
Needle Bearings
Before you press needle bearings in a bore always
remove any metal protrusions in the bore or edge of
the bore. Before you press bearings into position
put petroleum jelly on the inside and outside
diameter of the bearings.
Don 8-86531
Gears
Check all gears for wear and damage. Replace
gear$ that have wear or damage.
Oil Seals, 0-Rings And Gaskets
Always install new oil seals, o-rings and gaskets.
Put petroleum jelly on seals and o-rings.
Shafts
Check all shafts that have wear or damage. Check
the bearing and oil seal surfaces of the shafts for
damage.
Service Parts
Always install genuine Case service parts, when
ordering refer to the Parts Catalog for the correct
part number of the genuine Case replacement
items. Failures due to the use of other than genuine
Case replacement parts are not covered by
warranty.
Lubrication
Only use the oils and lubricants specified in the
