Aura Series
The Aura Series was originally designed with a reinforced 15/16” flat Kevlar/urethane belt. Later, a line
extension was designed using cables. Belts and cables are NOT interchangeable.
Belts
Belts should be tensioned if you notice the belt riding to one side of a pulley or if range of motion loose is
seen.
Belt Tensioning Procedure:
1. Loosen bolts on ‘fold over’ clamp or ‘barrel’ clamp
2. Using your hand, pull any slack out of the belt and using a pliers on the cut end of the belt,
pull to remove that slack
3. Tighten bolts using the instruction below
Note: It is recommended to leave three (3) squares of extra belt showing on the opposite side of the
clamp to give you something to grab onto when tensioning.
‘Fold over’ type clamp;
• Add Red Vibra-Tite thread locker to the 4 bolts threads then tighten to 5 N-m using a torque
wrench.
• The bolts should be tightened in a uniform pattern to ensure the clamp is applying consistent
pressure to the belt (see the image below). Tighten the 4 bolts a few turns each until the 5 N-
m torque is reached on each. Do not tighten 1 bolt all the way to 5 N-m before moving onto
the 2
nd
bolt, etc. Tighten a little to each bolt until 5 N-m is met.
‘Barrel’ type clamp;
• Add Red Vibra-Tite thread locker to the 2 bolts threads then tighten to 30 N-m using a torque
wrench. Like the fold over clamp, tighten each bolt a little at a time until proper torque is met.
