Adjusting The Belts; Adjusting The Traction Pedal - Toro 03422 Operator's Manual

4. After adjusting the pump plate, check the neutral switch
operation and, if necessary, adjust it as follows:
A. Loosen the locknut securing the switch adjusting
screw. Thread it away from the switch until the
capscrew head clears the switch.
B. Rotate the adjusting screw toward the switch until
circuit through the switch is made. Then, turn the
adjusting screw toward the switch an additional
2-1/2 turns.
C. Tighten the locknut

Adjusting the Belts

Make sure the belts are properly tensioned to ensure proper
operation of the machine and prevent unnecessary wear. On
new belts, check the tension after 8 hours operation.
Hydraulic Pump Belt
A new hydraulic pump belt should be tensioned so that it
deflects 0.12 inch with a 15–17 pound load applied midway
in the span of the belt. A used belt should be tensioned so
that it deflects 0.12 inch with a 11–13 pound load applied
midway in the span of the belt.
Tighten the nut on the adjustment rod (Fig. 56) until the
desired belt tension is attained.
Note: Tighten the belt to eliminate slippage (squealing
under load) but do not overtighten.

Engine Belt
The engine belt should tensioned so it deflects 0.2 inch with
a 2–3 pound load applied midway between the crankshaft
and alternator pulleys.
1. Loosen the bolts securing the alternator to the engine
and adjusting strap.
2. Adjust the belt (Fig. 57) to the proper tension and
tighten the bolts.

Adjusting the Traction Pedal

If the traction pedal contacts the footrest when it is pushed
fully forward or maximum forward traction speed is
unattainable, an adjustment to the traction pedal linkage is
required.
1. To expose the traction rod, remove the screws securing
the right fender to the frame and remove the fender.
2. Loosen the jam nuts on each end of the traction rod
(Fig. 58).

3. Rotate the rod until the required pedal clearance or
traction speed is attained.
4. Tighten the jam nuts securing the traction rod
adjustment.
5. The stop for reverse travel (under the pedal) may be
adjusted for slower travel. Speeds in excess of 3 MPH
are not recommended.
