Adjustments

Alternator Belt Adjustment

Make sure belt is properly tensioned to assure proper
operation of the machine and prevent unnecessary
wear. On new belts, check tension after 8 hours opera-
tion.
The alternator belt should be tensioned so it deflects
0.20 inch (0.51 cm) with a 2 to 3 pound (8.9 to 13.3 N)
load applied midway between the crankshaft and alter-
nator pulley.
1. Loosen bolts securing alternator to engine and ad-
justing strap.
2. Adjust belt to proper tension and tighten bolts.

Valve Clearance Adjustment

Initially, adjust valves after the first 50 hours of opera-
tion, and every 400 hours thereafter.
1. Remove breather hose and cylinder head cover
from the engine.
Note: Adjust valves when the engine is cold. Set the
No. 1 cylinder to top dead center. Adjust clearances of
the intake/exhaust valves of No. 1 cylinder and exhaust
valve of No. 2 cylinder. Then, turn the crankshaft coun-
terclockwise 240 (viewed from front) to adjust clear-
ance of intake valve of No. 2 cylinder and intake/exhaust
valves of No. 3 cylinder.
2. Loosen nut and adjust clearance of both intake and
exhaust valves to 0.0078 inch (0.2mm).
3. Install cylinder head cover and gasket. Torque
screws to 7 to 9 ft–lb (0.97 to 1.24 kg–m). Install breath-
er hose.
