This symbol is used to indicate

presence of hazards that can cause

minor property damage.

CAUTION

1. Install alternator as shown in Figure 1. Alternator

has two pairs of mounting lugs, so it can be

either right or left mounted. One of the oppo-

site mounting lugs can be used for tensioner.

When adjusting belt tension, mounting foot

hardware must be loosened. After belt tension is

adjusted or when mounting alternator, tighten

drive end mounting hardware before anti-drive

end hardware.

Slip bushing located in anti-drive

end mounting lug must be

securely tightened against

alternator mounting bracket

on engine. Failure to do so can

result in broken mounting lugs.

a. Use hardened washers between aluminum

surfaces and bolt heads and nuts.

b. OEM units are shipped with pulley, hardened

washer and locknut installed.

c. Aftermarket units are shipped with shaft

collar, hardened washer and locknut. Remove

and discard shaft collar. Install pulley and

furnished hardened washer.Torque locknut to

163 Nm/120 lb. ft.

3. Choose wire gauge capable of handling maximum

alternator output with no more than 0.4 V drop on

each leg from alternator to battery.
