6.Remove existing A, B, C and D change gears (see Figure 52). Note: Some gears may be difficult to remove due to excess grease and debris. Once they are removed, clean gears with mineral spirits and wipe them down with a clean rag.

7.Replace A and C gears with 20T gears, and B and D gears with 80T gears (see Figure 55 on Page 43). The printed gear letters should face outward.

8.Reposition adjuster so gears mesh, tighten adjuster hex nut, then secure gears with cap screws and flat washers removed earlier.

9.Re-install end cover.

10.Push half nut lever down to engage power feed (see Figure 53).
