Step 25. Seal the drive train by placing the bottom chassis cover

Step 21. Slide the tensioner arm assembly down over the belt (26) and connect the slot in the tensioner arm (21) with the tensioner arm
bushing (34) as indicated in Figure 16A.
!
Step 22. Slowly start rotating the tensioner arm around the tensioner bushing (34) in a clockwise direction as shown in Figure 16B. While
rotating the tensioner arm assembly, slightly pull upward to keep the tensioner arm (21) locked and rotating to the tensioner bushing (34). The
belt (26) should be positioned between the drive pulley (36) and the tensioner arm (21).
!
Step 23. Place a #4 hardened washer (37) over a 4-40 x 1/4" button head screw (38).
!
Step 24. Once you have the belt (26) wrapped around the drive pulley (36), and belt tensioner (21) in position, as shown in Figure 16, secure
the tensioner assembly by threading the 4-40 x 1/4" screw (38), with washer (37), through the chassis (27) into the tensioner arm (21). With the
4-40 x 1/4" screw about one turn loose, push down on the flat part of the tensioner (21) and set the desired belt tension, tighten the screw (38).
The belt should move 1/4" (6mm) to 3/8" (9.5mm) up and down for the ideal tension.
