Remove starter (3) and starter adapter (4).NOTECheck ring gear to assure that teeth are notdamaged.b. Installation.Install the starter (3, fig. 14-9) onthe flywheel housing in reverse order of removal.14-26. Brushes Inspection and Replacement.ceed as follows:a. Gain access to the starter motor as inparagraph 14-25.b. Remove the starter commutator end headassembly, (11) (fig, 14-10) as follows:(1) Scribe a mark on end head (11) and frame tolocate relative position at assembly.(2) Remove lead assembly (3, fig. 14-10) by mov-ing nut (l), washer (2) and nut (4), lockwasher (5), flatwasher (6), phenolic washer (7), flat washer (8), and rub-ber washer (9).(3) Remove seven bolts (10).(4) Remove commutator end head assembly (11),gasket (12), and washer (13).(5) Remove insulator (14) and insulating bushing(15).c. Remove four brush springs (21) by lifting endof spring from slot and sliding spring from mountingarm. Remove four brushes (22) from brush plate (18).(1) Tag and disconnect electrical leads frombrushes (22) by removing screw (19) and washer (20).(2) Measure the length of each brush. If anybrush is less than 3/8 inch long, replace the complete set ofbrushes with new brushes.d. Install the brushes as follows:(1) Clean all brushes with a clean, dry cloth only.Do not permit dry cleaning solvent to come in contactwith the brushes.(2) Install brushes in reverse order of removal.e. See figure 14-10 and install the commutatorend head (11) in reverse order of removal.14-27. Starter Solenoid.To replace the starter solenoid (29, fig. 14-10) proceed asfollows:a. Removal.(1) Disconnect electrical connections to solenoid.(2) Remove screws (26, fig. 14-10).(3) Remove plug (23) and gasket (24).(4) Slide solenoid (29) toward brush end of motor.(5) Slip back rubber boot and insert screwdriverin slot of solenoid core to prevent core from rotatingwhile removing nut (25).(6) Remove solenoid (29).b. Installation.(1) Install starter solenoid in reverse order ofremoval and perform steps (2) and (3) below.(2) Place starter on bench and apply 24 vdc to thestarter solenoid terminals.(3) With 24 vdc applied to starter solenoid ter-minals, the starter drive pinion should be observed mov-ing forward and spinning.c.
