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 48mm across flats in a vice
• place the machine in the wrench on the flats which are closest
to the motor
• untighten the nut with a special 40mm wrench, left-hand thread
• remove the coupling sleeve and the drive pinion
4- disassembling the reduction gear stages
• place a special wrench of 48mm across flats in a vice
• the machine should imperatively be placed on the flats of the
gear ring of the first 2 stages
• using a torch, heat the connecting casing of the motor
• using a special wrench of 40mm across flats, untighten the
motor - left-hand thread - and its connecting casing
• place the special wrench of 40mm across flats in the vice
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.
