4.3.4 Drive Belt Tension:
The drive belt is tightened by moving the engine base
with the mount positioning bolts.
WARNING: Rotating Part Hazard
Turn off engine and wait for all belts to
stop rotating.
1. Open the guard over the V-belt drive system.
2. Loosen the jam nuts on the engine mount
positioning bolts.
3. Use the nut on the position bolt to move the
motor mount to the required position to set belt
tension.
4. Check the belt tension.
5. Calculate the tension. See Figure 73:
- Measure the length of span between pulleys.
- Allow 1/64” of deflection per inch of span.
6. Tighten the jam nuts to their specified torque.
7. Place guard over the belt and bolt to secure.
WARNING: Rotating Part Hazard
Always install and secure guards before
starting engine and resuming work.
4.3.5 Check Pulley Alignment:
1. Use a straight edge across both drive and driven
pulleys to check alignment.
2. Use the tapered lock hub in the center of the
pulley to adjust the position of a pulley if required.
3. Move a pulley to align if there is more than a 1/32
inch gap between the edge of the pulley and the
straight edge.
