REPLACEMENT OF BELT:
1. Remove cover (Fig. 15, Item 32 ) from unit.
2. Remove Tensioner Assembly (Fig 10). Then loosen screws (Fig. 15, Item 27). Move gearbox forward to
allow removal and replacement of belt.
3. Retighten screws into gearbox until they bottom out. (Fig. 15, Item 27) This will align gearbox correctly.
4. Replace tensioner with bolts and leave loose to allow adjusting belt tension.
5. Tighten belt as shown in Figure 10. When properly tightened the deflection play should be 1/4 inch when
pushing hard with thumb. (20 ft/lbs)
NOTE: When placing belt on pulleys and inserting the tensioner against belt, ensure cogs on belt are engaged into cogs on
pulleys before tightening belts. Rotating upper pulley while holding the tensioner against the belt will allow proper engagement
of cogs prior to tightening.
