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.

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.
