TV60RE Blower Drive Belt
• To adjust belt tension, loosen the ad-
justment bolt and the bolt where the
tensioner pivots. Position the tensioner
to allow for proper deflection. Re-tight-
en both bolts.
• Apply 20 lbs. of pressure to the mid-
point between the electric clutch and
blower pulley. The belt should deflect
¾ in.
• Too much tension (minimal deflection)
can damage the belt and bearings. Too
little tension (excessive deflection) will
allow belt to slip and decrease blower
performance.
• To replace the drive belt, loosen the
belt tensioner and remove the old belt.
Install the new belt, and follow the same
procedure for adjusting tension as
described previously.
• Inspect the belts frequently and main-
tain the correct tension and alignment.
TV60RE Hydraulic Pump Belt
• To adjust the belt tension on the hy-
draulic pump, loosen the adjustment
nut and the nut where the pump pivots.
• Position the pump to allow ¼ in.
deflection at the mid-point. Re-tighten
both nuts.
• If a belt shows signs of wear, such as:
fraying, cracking or missing pieces;
replace it immediately.
