GENERAL INFORMATION
Cleanning
Clean all metal parts except bearings, in a suitable
cleaning solvent 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 a suitable cleaning
solvent, 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 a visual inspection for
indications of wear, pitting and the replacement of
parts necessary to 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 suitable cleaning solvent 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.
Gears
Check all gears for wear and damage. Replace gears
that have wear or damage.
Oil seals, O-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 NEW HOLLAND service parts.
When ordering refer to the Parts Catalog for the
correct part number of the genuine NEW HOLLAND
replacement items. Failures due to the use of other
than genuine NEW HOLLAND replacement parts are
not covered by warranty.
Lubrication
Only use the oils and lubricants specified in the
Operator’s or Service Manuals. Failures due to the
use of non-specified oils and lubricants are not
covered by warranty.
