General data
Pins and bearing inspection
MS0002
• Reinforced visual inspection with disassembling of certain elements to reach the bushes or bearing Section D -
Inspection and maintenance schedule : In addition to the above cited criteria, verify the following :
• Check the presence and the position of the bushes and bearings.
• Check the absence of shaving in periphery of the pins.
• Check the absence of heavy abrasion, wear or oxidation of the bushes and bearing.
• Check the absence of deformations, cracks or breakage of the bushes and bearing.
• Check the absence of radial gap > 0,5 mm (19690 µ in) on the pins.
• Complete disassembling of the pins, bushes and bearing Section D - Inspection and maintenance schedule :
In complement of the inspections above cited, it is necessary to check :
• For the stages :
• Check the presence of material of friction.
• For the bearings :
• After disassembling, protect the bearing from pollution and shocks.
• Clean the bearing with a suitable solvent.
• Check the absence of shaving in the housing of the bearing and/or the bearing.
• Check the absence of heavy abrasion, wear, oxidation, deformations of the balls (or rollers) and the ball races.
The periodicity can evolve under the following conditions Section D - Inspection and maintenance schedule :
• Abnormal noise during movements of the structure.
• Prolonged storage of the machine ( 6 months).
• Specific storage and use Environment (strong moisture and salinity of the air).
5 - Criteria of replacement
The pins, stop pins, bushes and bearing must be replaced as soon as one of the anomalies quoted above is noted.
Bearing and bushes must be imperatively changed at the end of 10 years of use.
6 - Procedure of reassembly
6.1 - P
INS AND BUSHES
When reassembling bearings and pins ensure that :
• Lightly lubricate the housing into which the bearing is to be installed.
• Insert the bearing using a bearing drift, preferably out of mild steel.
• The bearing, the bearing drift and the bearing housing must be correctly aligned during the assembly
process.
• The recommended values for the bearing drift are given on the diagram below :
