Alternator - CHRYSLER: Overhaul: Reassembly
NOTE:
Insure correct rectifier is installed. Identifying part numbers are stamped on rectifier case and rectifiers are color coded: red for positive and black for negative.
- On early models, install rectifiers and connect stator leads with rectifier leads using rosin core solder.NOTE: Hold rectifier lead wire with pliers just below joint while soldering.
Pliers will absorb heat from soldering and will protect rectifier. Push stator leads into slots cast in end shield and cement in position with MoPar cement, Part No. 2299314 or equivalent to prevent interference with rotor fan.
- Position rectifier end shield bearing on suitable base tool (C-3925 or C-4201) and place alternator end shield on top of bearing so it is properly aligned with top part of suitable bearing press tool and press into place until bearing bottoms.
- Insert drive end bearing in shield and install bearing retainer plate. Position bearing and drive end shield on rotor shaft, and while supporting base of rotor shaft, press bearing end shield into position on rotor shaft with an arbor press and suitable adapter (C-3858).NOTE: Make sure bearing is installed squarely.
- Install pulley on rotor shaft. Shaft of rotor must be supported so all pressing force is on pulley hub and rotor shaft, and not on bearings. Do not hammer pulley on.
- On early models ensure heat sink is in place and install capacitor stud thru heat sink and end shield. Install insulating washer, lock washer and lock nut and tighten.
- On late models, install output terminal stud and insulator thru end shield. Install heat sink assembly over studs, guide rectifier straps over studs of terminal block and install capacitor. Slide negative rectifier and heat sink assembly in place, position straps and install screws.
- Position stator over rectifier end shield and install winding terminals on terminal block and press stator pins into each end shield. Position rotor and drive end shield over stator and rectifier end shield and install thru bolts. Compress both ends manually and tighten turn bolts evenly to 20-30 INCH lbs.
- Install field brushes in insulated holders. Position vertical and horizontal field brushes in proper location in rectifier end shield. Place on insulating washer on each field brush terminal and install lock washers. Be sure that brushes are not grounded. Rotate pulley slowly by hand to be sure rotor fan blades do not hit stator winding leads.
