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

proper terminals:
• [AG1] and [AG2] to G terminal (1)
• [AB1] and [AB2] (SN 0160003689 & Before) or
Fusible Link Cable (SN 0160003690 & After)
to B terminal (2)

4. Place a 3/8" square drive ratchet into the square
hole on the tensioner bracket (9). Apply pressure
against the tensioner bracket and properly route the
fan belt (10) onto the alternator and engine pulleys.
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.
Connect the lower negative battery cable (11) to the
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).
