DRIVE BELT
1.The drive belt may be accessed by removing the top, right, and rear covers as shown in previous sections.
2.Remove the drive pulley bearing plate and slip off the drive belt as shown in Figures 19 - 21.
3.Lift the idler pulley spring off the threaded stud, and release tension on the idler pulley assembly. Note the path of the belt, then remove it through the back of the unit (Figure 40).
4.Inspect the belt for excessive wear, and replace if worn out or cracked. Make a loop with the new belt, and insert it into the rear of the unit, over the pivoting idler pulley assembly and toward the horizontal trans- mission pulley (Figure 41).
5.Wrap the belt around the transmission pulley, beveled edge in, and engage the lower idler pulley and bottom of the large angled pulley (Figure 42).
6.While maintaining light tension on the belt with one hand, wrap the drive belt around the lower idler pul- ley and angled pulley, and hold in place with the other hand (Figure 43).
7.Pull the pivoting idler pulley assembly back up into normal position, wrapping the drive belt around the upper idler pulley. At this point, the slack loop at the other end of the belt should be toward the drive belt pulley plate mounting area (Figure 44).
8.Pull the slack end of the drive belt toward the front of the unit, and loop it over the drive pulley drive shaft as you place the drive pulley drive shaft into the vacuum nozzle housing shaft opening (Figure 45).
