SETTING THE AUGER BELT TENSION
STEP 59: (SEE FIGURE 57)
• Pull the tensioning chain until the end of the spring is
pulled through the hole in the side of the Clutch/Idler
assembly. Install a 1/8" hairpin cotter (KK) through

Clutch/Idler assembly.
IMPORTANT: For correct belt tension, the 1/8" hairpin
cotter must attach to the end of the spring, not to the
chain.
NOTE; To prevent the chain from dragging on the
ground, loop the end of the chain though the pivot lock
pin. Refer to figure 45 on page 20.
