Disassembly
1- disconnect the cables from the tool
2- disassembling the output shaft
• lay the machine horizontally on a table
• remove the retainer pin from the output shaft
• be careful of the spring reaction
3- disassembling the motor
• place a special wrench of 56mm across flats in a vice
• place the machine in the wrench on the flats which are closest
to the motor
• heat the gear ring with a torch
• untighten the motor - left-hand thread - using a special wrench
of 56mm across flats
• remove the coupling sleeve and the drive pinion
4- disassembling the reduction gear stages
• place a special wrench in a vice: 56mm across flats if there are
3 stages, 49mm across flats if there are 2 stages
• the machine should imperatively be placed on the flats of the
2nd stage gear ring or on the flats of the strain gauge if there
are only 2 stages.
To prevent any risk of ovalisation, make sure that the planet cages are in their
housings before tightening the gear ring nut.
Under no circumstance shall the torques be applied at the active section of the strain
gauge when assembling and disassembling, to avoid damaging the strain gauge.
Complete reassembly
Reassembly does not pose any problem in particular.
It is important to follow all the indications which are provided, in the form of pictograms, on the drawing opposite.
