ESTING
IMPORTANT: Torque hubs should always be roll and leak tested before disassembly and after assembly to make sure
gears and sealants are working properly.

Gears should be able to rotate by applying a constant force to the axle. Some gear packages roll with more
difficulty than others.
Do not be concerned if gears seem to roll hard as long as they roll with consistency. If you feel more drag
only at certain points the gears are not rolling freely and should be checked for improper installation or
defects.

The purpose of a leak test is to make sure the unit is air tight. Pressurize hub to 0,35 bar (5 PSI). Torque
hub has a leak if the air pressure starts to fall after hub has been pressurized.
Use soap and water on hub to detect location of leaks. If a leak is detected, seal or O-ring must be
replaced.
