Loctite Applications
We use Loctite, or similar product, in a
variety of applications in fabrication and
assembly of Fisher and LeMond bikes, and
components on those bikes. Here's a partial
list, and the recommended Loctite product:
Crown pinch bolts . . . . . . . . . . . . . . . . . . . . . . . 242 Blue
Brake arch bolts . . . . . . . . . . . . . . . . . . . . . . . . 242 Blue
Cantilever studs . . . . . . . . . . . . . . . . . . . . . . . . 242 Blue
Pivot axle bolt, left . . . . . . . . . . . . . . . . . . . . 290 Green
Pivot axle bolt, right . . . . . . . . . . . . . . . . . . . . . 242 Blue
Pivot bushings, frame/swingarm . . . . . . . . . 290 Green
Shock mount bolts . . . . . . . . . . . . . . . . . . . . . . 242 Blue
Use Loctite carefully. Follow the instruc-
tions on the package, avoiding contact with
your skin, or inhaling the vapors. As noted
on the package, Loctite contains a known
carcinogen.
For Loctite to work correctly, the parts
must be clean and dry, with no grease, oil,
or dirt. Loctite Kleen 'N Prime is an excel-
lent cleaner and will reduce fixture time.
With blue 242 Loctite, apply to the threads
prior to assembly. It will set up in 20 min-
utes, with full cure taking 24 hours. With
green 290 Loctite, application is recom-
mended after assembly. However, this can
be impractical with hidden threads, like
on the rear suspension pivot bolts or rear
suspension bushings. 290 is set in 3 min-
utes, and again requires 24 hours for a full
cure. Please do not confuse Loctite 290 with
Loctite 640, which is also green, as 640 can
make disassembly much more difficult.
Highly Recommended Grease
Applications
Most threaded fasteners will benefit from
the application of a light grease-type lubri-
cant. This prevents corrosion and galling, as
well as allowing a tighter fit with a given
torque. For this reason, it’s a good idea to
lubricate almost all threaded fasteners. But
some fasteners and parts interfaces really
need grease. Here are a few items requiring
grease application:
•Seatpost/seat tube interface. Grease the seatpost
where it inserts into the frame on all aluminum
and steel frames.
•Bottom bracket threads. We recommend apply-
ing grease to all bottom bracket/frame inter-
faces, as well as the bearing/cup interfaces. This
prevents corrosion and will virtually eliminate
creaks, a common complaint among riders with
cartridge bottom brackets.
•Stem/steerer interface. Grease the quill of con-
ventional stems where they insert into the fork.
With Aheadset type stems, a light oil is rec-
ommended, as grease may make it difficult to
properly secure this type of stem to the steerer.
•Stem/handlebar/bar end pinch bolts. Any and all
of these fasteners are small, so corrosion or
galling can really cause problems. Its also criti-
cally important to the riders safety that they
be correctly tightened. Grease both the threads,
as well as the bearing surface of the fasteners
which rotate against the fixed part.
Places to Avoid Grease
•Bottom bracket axle/crank arm interface. Avoid
greasing the tapered spindle of a bottom brack-
et, as this may allow the crank arm to insert
an incorrect distance onto the bottom bracket
spindle. This can cause crank arm clearance
problems with the frame, or incorrect chainline
with the specified components. A light oil will
adequately prevent any unwanted corrosion in
most cases.
