How to use a torque spanner when loosening? Upside down? On reverse pitch?
This tutorial explains how to use a torque spanner "upside down", i.e. counterclockwise, when loosening. This is particularly useful when tightening on a reverse thread.
- Torque spanner
- Torx spanners or Phillips screwdriver
Presentation of the torque spanner
The operation consists of turning the tip of the torque spanner so that it can torque a screw or nut with an inverted pitch, counterclockwise. This type of reverse thread is found on shafts/nuts on maxiscooters (Piaggio, Aprilia, Gilera, BMW, etc.).
Remove the torque spanner plate (1st screw)
Using a Torx or Phillips screwdriver (depending on the model), unscrew the first screw holding the plate at the head of the torque spanner.
Remove the torque spanner plate (2nd screw)
Then, unscrew the second screw holding the plate in place.
Pull out the end of the torque spanner
Once the 2 screws have been unscrewed, the torque spanner mechanism is removed.
Turn the tip over
The tip is then turned over and put back in its housing.
Turning the tip over (continued)
The tip is now in place in its housing.
Put the plate back in place
The plate can then be repositioned in its original position.
Screw in the 2 screws to hold the plate in place
Using a Torx or Phillips screwdriver, depending on the model, the 2 screws holding the plate at the head of the torque spanner are tightened.
The torque spanner is ready!
The torque spanner is now ready to tighten on a reverse thread, counterclockwise.
