upper (“longer”) mounting capscrew (7) through the

rear mount and alternator. Loosely secure the

mounting hardware. DO NOT fully tighten the

hardware at this time.

mounting tab (8) on the engine and insert the lower

mounting capscrew (5). Tighten the lower capscrew

securely and torque to 18 lb-ft (24 Nm). Fully tighten

the upper mounting capscrew (7) and torque to

Check the tensioner pulley to verify that it is pivoting

freely to provide the proper tension on the belt.

Check for proper fan belt deflection. (Refer to

appropriate Owners/Operators Manual for general

information.)

negative battery cables (11 and 12) to both

batteries.

negative (-) terminal on the lower battery (13). Swing

the upper battery box (14) in and make sure that the

lip (15) on the upper battery box slides below the

knob (16). Secure in place with the knob (16).
