Maintenance
FIG. 4.2
Replacing Belt
1. Deck should now be in the orientation shown (Figure 4) before installing new belt,
clean any debris from the deck before moving on.
2. Install belt around the center gear; pull the excess through the gap by the counter
weight (Figure 4.1).
3. Keep the smooth side of the belt against the idlers and flip the belt over the deck.
The teeth on the belt will face outward.
4. A properly installed belt should appear as shown (Figure 4.2).
5. Turn one tensioner into place and install the bolt (Figure 4.3).
6. Push the second tensioner into the belt until the mounting hole lines up with the
block; install the second bolt.
7. Once both tension blocks are installed, remove the collapsing bolts.
8. Use pliers to rotate the shaft on the bottom of the machine so the key is in the 12
o’clock position (Figure 4.4).
9. Turn the deck so the keyway in the hub is also in the 12 o’clock position (Figure
4.5). Note: Use anti-seize on the shaft and in the center of the deck to protect
against corrosion.
10. Hold the motor straight while lining up the shaft with the hub in the deck.
11. Press evenly on the top of the motor or deck until the shroud is seated on the deck.
12. Re-install the four bolts around the base of the reducer. The shroud may need to be
rotated to line up with the holes. Do not crossthread bolts when installing.
13. Test machine thoroughly to ensure correct operation.
