i.
Attempt to rotate the pressure tube a few degrees in either direction. If the anti-rotation balls
in the end cap have engaged properly, the tube will not be able to rotate. If the anti-rotation
balls are not engaged properly, slowly rotate the pressure tube in each direction until the balls
are engaged properly.
j.
Continue tightening the locking ring with the IDA body wrench. Tighten the locking ring firmly,
but do not over-tighten, as too much torque will ruin the anti-rotation features within the
assembly.
k.
Use the bicycle tire pump to apply 10psi – 15psi of pressure to the air fill valve in the end cap.
This will fill the bladder and force any air trapped in the passages of the base valve to be purged
up through the middle of the pressure tube. Do not fill the end cap with air from a constant
source such as an air compressor. This could cause the bladder to over expand and destroy the
bladder or unseat the sealing ends of the bladder.
l.
Leave the 10psi – 15psi of air pressure in the unit until after the damper has been completely
assembled. This will aid in purging the air from under the piston assembly when the head
assembly is being installed into the base assembly.
m.
Remove the oil drip cup, cover the open end of the pressure tube, and store the assembly with
the open end of the pressure tube facing up. This will ensure that the oil remains in the
reservoir around the bladder.
