Disassembly
1- disconnect the cable from the tool by untightening the
nut
2- disassembling the output shaft
• lay the machine horizontally on a table
• be careful of the spring reaction
• move the retainer pin from the output shaft
3- disassembling the motor
• lace a special wrench of 56mm across flats in a vice
• place the machine in the special wrench, on the flats which are
closest to the motor
• eat 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 1st reduction gear stage
• place a special wrench of 72mm across flats in a vice
• the machine should imperatively be placed on the flats of the
strain gauge
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.
