General information regarding torque arms

Torque arms can absorb the reaction torque and the weight force of the gearbox.
NOTICE
Dangerous transient torques due to excess backlash
Take care to prevent the torque arm causing excessive constraining forces, e.g. due to the
driven shaft running out-of-true.
NOTICE
Impermissible gearbox loading caused by incorrect mounting
Do not tension torque arms when mounting.
NOTICE
Damage to the rubber elements caused by solvent
Solvents, oils, greases, and fuels damage rubber elements.
