6. Remove the rocker arm from the
deadshaft (see Figure 3). Discard all of
the old hardware (Oilite washer, thrust
washer, snap ring).
7. Loosen and push the shaft collar all the
way onto the deadshaft (see Figures 4 and
5).
8. Inspect the deadshaft for smoothness. A
badly worn or damaged shaft may require
sanding to smooth it enough for the new
rocker arm to slide on.

9. The kit contains Oilite washers in two
thicknesses. Slip one of the thinner Oilite
washers onto the deadshaft as shown in
Figure 6.
10. Wipe the deadshaft with the supplied
alcohol wipe. Save the wipe; it will be
used later in this procedure and during
the second rocker arm installation.
11. Apply a bead of green Loctite #620 thread
locking compound from the supplied
applicator tube all the way around the
deadshaft, about an inch (3 cm) from the
end (see Figure 7). Do not use more than
half of the compound in the tube.
12. Apply the remaining Loctite around the
inner surface of the rocker arm sleeve (see
Figure 8). Keep the compound at least an
inch (3 cm) from the edge of the sleeve to
avoid getting any compound on the new
bearings.

13. Rotate the rocker arm back and forth
while sliding it onto the deadshaft (see
Figure 9). This will spread the Loctite
evenly onto the deadshaft.
14. Wipe off any excess Loctite near the snap
ring groove with the alcohol wipe.
15. Install one of the thicker Oilite washers.
16. Install the new thrust washer onto the
sleeve next to the snap ring groove (see
Figure 11).

17. Install the new snap ring (see Figure 12)
18. Pull the rocker arm against the snap ring.
19. Slide the shaft collar tightly against the
Oilite washer and rocker arm housing (see
Figure 13).
20. Tighten the setscrew on the shaft collar
(see Figure 14).
21. Swing the rocker arm to verify free
movement. This will also provide
assurance that the Loctite has not seized
the bearing and sleeve together.
22. Reattach the user arm and pedal to the
rocker arm.
23. Reattach the lower rocker arm cover.
24. Reattach the outer deadshaft cover.
25. Repeat steps 1-23 with the other rocker
arm. The Loctite on the first side will be
curing while the second rocker arm kit is
being installed.
26. Allow the Loctite on the second rocker
arm kit to cure undisturbed for at least 30
minutes.
