16.Place belt between idler pulley and the belt keeper bracket.

17.Using pliers, rotate the belt keeper bracket so that it snaps into slot on the idler bracket.

18.Tighten the idler pulley bolt and locknut ½ turn using two 7/16" wrenches. See Figure 22.

19.Place belt between the two pulley halves on the crankshaft. Make sure to route the belt inside the belt guard pin. See Figure 26.

IMPORTANT: For proper assembly, it is essential to keep the assembly positioned as shown in Figure 26.

20.Pinch belt together so that it is not in the pul- ley groove, and the lower pulley can be pushed towards the engine. See Figure 27.
