until the brake pedals have 13 to 25 mm (1/2 to 1
inch) of free travel.

correctly.
E. Install the brake-adjustment cover.

Belt Maintenance

Servicing the Alternator Belt

Service Interval: After the first 10 hours
Every 100 hours
1. Proper tension allows 10 mm (3/8 inch) deflection
when you apply a force of 44 N (10 lb) on the belt,
midway between the pulleys.
2. If the deflection is not 10 mm (3/8 inch), loosen the
alternator mounting bolts

2. Mounting bolt
3. Increase or decrease the tension of the alternator belt
and tighten the bolts.
4. Check the deflection of the belt again to ensure that
the tension is correct.
Tensioning the Blade-Drive
Belts
Service Interval: After the first 10 hours—Check the tension
of the blade-drive belt.
Every 50 hours—Check the tension of the blade-drive
belt.
When properly tensioned, the extension spring (hook to
hook) measurement should be approximately 8.9 cm ±
0.63 cm (3.50 ± 0.25 inch) (inside). Once you achieve the
correct spring tension, adjust the stop bolt (carriage bolt)
until there is approximately 0.32 cm ± 0.152/.000 cm (0.125
+0.060/-0.000 inch) clearance between the head of the bolt
and the idler arm (Figure
Note: Make sure that the belt is positioned on the spring
side of the belt guide (Figure
