CHECKING NEEDLE BEARING
MIGRATION
Migration of the needle bearings in medium and long
travel Headshok forks may occur over time and is a
regular service item and generally not a warranty
issue. All linear bearing systems will experience
migration over a period of time, and even million
dollar indu stria l ap plica tio ns req uire period ic
resetting, or disassembly and rebuilding.
1. With the bike in a work stand, loosen the 5mm
Allen bolt of the top clamp.
2. MAX - Remove the red rebound adjustment
knob by loosening (not removing) the 2 mm
Allen screw and lifting off the adjuster knob. Be
sure to note the two small springs, balls, and
O-ring.
JAKE - Remove the red rebound adjustment
knob by loosening (not removing) the 2mm
Allen wrench and lifting the knob off.
3. Remove the upper collar from the outer tube
using a green Park pin spanner or a 40mm
headset wrench.
4. Compress the fork exposing the spring
assembly.
5. Push the entire bottom out assembly down
below the top of the spring.
6. Slightly pull down on the spring so that you
can remove the black aluminum sleeve, the
plastic preload spacer nested behind it, and
any metal preload shims that may be installed.
NOTE :
Metal preload shims are not installed at the
factory.
7. Once the two sleeves are removed, take
notice of the 8mm wrench flats.
8. Using an 8mm open ended wrench, hold the
shaft on the flats and unthread the black
anodized outer cap and remove it using a
30mm open ended wrench.
9. Remove the top spring washer and spring
from inside the fork.
10.Carefully remove the O-ring from the black
anodized outer cap and reinstall the cap hand-
tight onto the shaft.
11.Next, place just the black, 30mm, aluminum
damper sleeve onto the black anodized outer
cap.
12.Now, fully extend the telescope to its
maximum length. If 1 mm of the aluminum
damper sleeve is exposed above the top of the
outer tube, the bearings have not migrated
and you may begin reassembly of the fork. Go
to Reassembly.
If more than 1 mm of the sleeve is visible
bearing migration has occurred; the bearings
must be reset before reassembly. Go to
