Internal Floating Piston (IFP) Installation
Apply a very liberal amount of SRAM® Butter grease to the
new B1 IFP.
Fill the groove on
both
sides of the IFP, and coat the outer and inner
surfaces.
NOTICE
The outer and inner surfaces must be coated with grease to prevent
stiction. The groove on
both
sides of the IFP must be completely filled
with grease to prevent air pockets from developing under the IFP.
Stiction and air pockets will negatively affect seatpost function.
Insert the IFP into the upper post and onto the IFP tube.
The IFP is symmetrical. Orientation of the IFP is not critical to
installation.
With one hand, hold the Reverb™ Post Bleed tool in place. With the
other hand slowly press the IFP into the upper post with your thumb
and finger; press only the edges of the IFP.
When the IFP is inside the upper post, level with the top of the tube,
use both thumbs to press the opposing edges of the IFP down into the
upper post. Stop when it is level with the top of the IFP tube.
NOTICE
Do not cover the center of the IFP and IFP tube during installation. Fluid
will be forced through the IFP tube and will push the Reverb Post Bleed
tool out of the upper post head, causing fluid to leak. If this occurs the
IFP tube and IFP must be
removed
and
reinstalled
.
⚠
WARNING - EYE HAZARD
When the IFP is pressed into the upper post fluid will be displaced and
may be ejected outward. Keep your eyes and face away from the end
of the upper post during installation. Wear safety glasses.
