Replacing the Deck Belt
Squealing when the belt is rotating, blades slipping when
cutting grass, frayed belt edges, burn marks and cracks are
signs of a worn deck belt. Replace the deck belt if any of
these conditions are evident.
1. Stop the engine, remove the key and disconnect the
spark plug wire(s) from the spark plug(s).
2. Remove the belt covers on top of the outer blade
spindles (Fig. 37).
3. Loosen the idler tension bolt and jam nuts, to relieve
tension on the idler pulley, then remove the idler
mounting bolt and slide idler pulley out through
opening (Fig. 37). Remove worn belt.
4. Install new deck belt pulling through space behind
gearbox pulley, then routing around two outboard
spindle pulleys and center spindle pulley. Check that
belt is in front of belt guide (Fig. 36).
5. Place idler pulley inside belt loop and slide into
opening. Place flats of idler hub into slot and loosely
install idler mounting bolt (Fig. 37).
6. Tighten idler tension bolt to achieve the correct
dimension between brackets (Fig. 37).
Important
Adjust new belt to 3 in. (77 mm), after 5–10
hours adjust tension to 2-5/8 in. (67 mm).
7. Tighten jam nuts and idler mounting bolt securely
(Fig. 37).
Note: Light belt contact with rear of gearbox bracket is
acceptable.
8. Reinstall the outer spindle covers (Fig. 37).
