Figure 3-35.(~) Remove fan guardby removing the sevenfan guard mounting screws ( 2 4 , f i g . 3 - 2 9 ) , which sec-ure the left and right handfan guards (26, 25) to theradiator shroud(36).(~) Remove alternator belt ( 7 , f i g . 3 - 3 5 )as follows:~. Loosen the alternator mounting bolt(8).2. Loosen the alternator adjusting bracecapscrew (5L and remove the alternator belt from itspulleys.@3. Remove the alternatorbelt (7) by care-fully manipu~ating it over the fan blades, Manuallyrotate the fan,as required, to facilitate belt removal.CAUTION—Do not force a belt over sharpmetal surfaces.(~) Remove the fan belts as follows:1. Manually position the fan blades togain access~o the idler pulley adjusling bracket cap-screw (6).2. Loosen idler pulley adjusting bracketcapscrew (6~andremove the front belt from its pul-leys.3. Remove the fan belts, one at atime, by ca~efully manipulating them over the fanblades.Manually rotate the fan, as required, to faci-litate belt removal.CAUTIONDo not force a belt oversharpmetal surfaces.(2) Installation.Installthe alternator andfan belts using appropriate removal steps in reverseorder and adjust the belts as described in p a r a g r a p h3 - 1 8 3 a ( 1 ) a n d ( 2 ) .NOTEReplace fan belts in sets.3 - 1 8 4 . B a t t e r y C h a r g i n g A l t e r n a t o r .a. Testing. Testing of the battery charging alter-nat;r ( 1 4 , f i g . 3 - 3 6 ) at the organizational maintenancelevel is accomplished by performing an operationalverification as instructed in stepc below.If the alter-nator output cannot be varied in a~cordance with therecommended voltage settings in step ~, shut downgeneratorset and proceed as follows:(1) Measure and adjust alternator belt tension,( p a r a 3 - 1 8 3 a ( 1 ) a n d ( 2 ) .(2) Check that fuse ( 2 1 , f i g . 3 - 3 6 ) is not burnedout ,(~) Cut lockwires (1)attached to connector(2)and receptacle mounting screw (3) and remove con-nector and lockwire.(3) Check battery connections for security.(4)If alternator(14)output is not correct afterbelt tension hasbeen adjusted, replace the alternator(14).b. Replacement.Replace the alternator (14), ad-jus~able brace (10), or mounting bracket (20) as fol-lows:(1) Removal.(a) Remove screw (4) and washers (5 and6)from alte~nator (1 4).(b)Remove belt tension and remove belt (7)from altei+nator pulley.(c) Remove screw (8) and washer (9) secur-ing adjust~ble brace (10)to alternator mountingbracket (20) and remove adjustable brace (10).(d) Remove screw (11) washer (1 2), spacer(13) and afiernator (14)from the mounting bracket(20).C h a n g e 33 - 8 9
