6.3.8. BELT SHEAVES & ALIGNMENT
Your leaf machine is equipped with QD Coupler style Quick Detachable bushings and sheaves.
NOTE: THE SHEAVES ARE NOT THE SAME SIZE. REINSTALL CORRECTLY.
REMOVAL:
•
Loosen & remove the three bolts that hold the sheave in place.
•
Reinsert the screws into the tapped holes on the sheave and tighten. This will free the sheave from
the coupler.
•
After the sheave is off, the coupler will slide off.
INSTALLATION & ALIGNMENT:
•
Clean tapered cone surfaces of sheave & coupler.
•
NOTE: DO NOT USE ANTISIEZE LUBRICANT ON TAPERED CONE SURFACES OR BOLT
THREADS.
•
Slide coupler into place, flange end first.
•
Slide sheave into place, deep opening first, and install bolts with lock washers into tapped holes in
coupler and hand tighten.
•
Use a straight edge to align the sheaves. Straight edge should touch both edges of each sheave at
the same time when properly aligned.
•
Tighten bolts on both sheaves approx. one turn. Recheck alignment. If alignment is good, torque
bolts.
•
Torque bolts as follows:
•
Motor Drive and Fan Driven Pulleys, ½ ”” bolts – 720 in./lbs (60 ft./lbs)
If both edges of one sheave are touching the straight edge, and only one edge of the other sheave:
Engine end – adjust engine screw jack bolts to change engine sheave angle.
Fan end – loosen bearing bolts to change fan shaft sheave angle.
