Adjusting Traction Drive Belt (Fig. 27) - Toro 38590 Operator's Manual

INSTALLED, AN ADJUSTMENT IS
REQUIRED. USE ONLY GENUINE TORO
REPLACEMENT PARTS.
1. Pull wire off spark plug and make sure wire does
not contact plug accidentally.
2. Remove (3) flange head capscrews securing belt
cover to engine frame and slide belt cover up
cables (Fig. 4).
3. Depress the auger/impeller control lever on the
right hand grip. Hold the lever and insert a .010"
(.25 mm) feeler gauge between a coil in the
center of the spring (Fig. 26). Adjust the cable to
achieve .010" (.25 mm) gap between the coils.
4. Loosen upper jam nut securing auger/impeller
cable to mounting bracket (Fig. 27).
5. Rotate bottom jam nut upward to increase belt
tension.
6. Tighten upper jam nut against bracket.
7. Recheck idler adjustment: refer to step 3.
8. Check impeller brake arm clearance by releasing
the auger/impeller lever. With the lever released,
there should be more than 1/8" clearance
between tab on impeller idler arm and brake arm
(Fig. 28). If there is less than 1/8" clearance,
belt must be replaced.

POTENTIAL HAZARD
Improper adjustment may cause injury if
auger/impeller turns when disengaged.
WHAT CAN HAPPEN
Rotating impeller or auger can cut off or
injure fingers or hands.
HOW TO AVOID THE HAZARD
Keep face, hands, feet and any other part of
your body or clothing away from
concealed, moving or rotating parts.
Make certain that impeller brake arm
clearance is maintained.
Do not adjust the auger/impeller drive belt
too tight because it may cause the
auger/impeller to turn when the control
lever is in the disengaged position. If this
occurs, decrease belt tension.
9. Reinstall belt cover and cable cover.
10. Check tension of belt by operating the
auger/impeller. If belt still slips, replace the
belt.
Adjusting Traction Drive Belt
(Fig. 27)
If the wheels do not turn when the traction lever is
depressed, the traction belt tension should be
increased. Whenever the belt is replaced, an
adjustment is required.
1. Loosen upper jam nut securing traction cable to
mounting bracket.
2. Rotate bottom jam nut upward to increase belt
tension.
Note: When adjusting cable, always rotate
nut one full turn at a time.
3. Tighten upper jam nut against bracket.
