MAINTENANCE

Output Square Drive

The only user maintenance required on HandTorque ® multipliers is the replacement of drive squares, should
they become damaged. To avoid internal damage (especially due to torque overload), the output drive
square / shaft have been designed to shear first. This saves major internal damage and allows easy square
removal.
In some instances the square drive will not be removable without disassembling the gearbox. In these cases
the HandTorque ® multiplier should be returned to Norbar or a Norbar approved agent for repair.
However, in many cases the square drive can be replaced without disassembling the gearbox.
In these cases remove the bolt holding the drive square in position (bolt will be either M4 or M5).
Then remove the broken / damaged drive square.
Fit the new drive square.
Fit the new bolt and tighten (4.7 Nꞏm for M4 bolts and 9 Nꞏm for M5 bolts)
FIGURE 12
Any other maintenance or repairs should be carried out by Norbar or a Norbar approved agent and should
form part of a service. Service intervals will depend on the type of usage of the tools and the environment in
which they are being used.
