GENERAL INFORMATION
Cleaning
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 Link-Belt service parts. When ordering refer to the Parts Catalog for the correct part number of the genuine Link-Belt replacement items. Failures due to the use of other than genuine Link- Belt 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.
