CHECK FAN TIP CLEARANCE
CAUTION
Be sure power take-off is disconnected before
checking or adjusting fan paddle clearance.
Refer to Figure 20.
Fan adjustment is made by adding or removing
shims (Figure 21) under fan shaft bearings. This
adjustment moves fan up and down. Adjustment is
also made with set screws at both front and hopper
side of fan housing. This adjustment moves fan
assembly from side to side.
1. Blower band must be properly tightened before
checking or making any adjustments.
2. Clean inside of fan housing, shown in Figure 20,
and paddle tips.
3. Check all paddle tips for proper length. Adjust
shear bar down snug and square against tip of
longest paddle. Loosen paddle bolts and adjust
short paddles up square and snug to shear bor,
not to exceed .015 clearance. See page 30,
paddle replacement for proper bolt torque.
Readjust shear bar, see shear bar adjustment
on page 31.
4. With a feeler gauge, measure across full width
of paddle to make sure paddle tips are square
with blower band.
