4.3.4 Drive Belt Tension:
ROTATING PART HAZARD
Turn off engine/motor. Disconnect power
source and wait for belts to stop moving.
First, set tension on “drive-to-countershaft” belt.
1. Open the guard over the V-belt pulley.
2. Loosen countershaft bearing mount anchor
nuts and jam nuts.
3. Use bearing mount position bolts to set
countershaft position and set belt tension.
Calculate the tension (See Figure 57):
- Measure the length of span between
pulleys
- Allow 1/64” of deflection per inch of span
4. Tighten bearing mount anchor nuts.
5. Tighten adjusting bolt(s) and lock nut(s).
6. Close and secure guard over pulleys.
Second, set tension on “engine-to-countershaft”
belt.
7. Open the guard over the V-belt pulley.
8. Loosen engine/motor mount nuts and jam
nuts.
9. Use motor mount nuts to set belt tension.
Calculate the tension (See Figure 57):
- Measure the length of span between
pulleys
- Allow 1/64” of deflection per inch of span
10. Tighten motor mount anchor nuts.
11. Tighten adjusting bolt(s) and lock nut(s).
12. Close and secure guard over pulleys.
