2. Position the rectifier end shield bearing on the base of tool C-4201. Place the alternator end shield on
top of bearing so that it is properly aligned. With the top part of tool C-4201 placed on the end shield, press
into place until it bottoms against it. (Refer to Figure 24-19.)
—NOTE—
New bearings are pre-lubricated. Additional lubrication is not
required.
3. Insert the drive end bearing in the drive end shield and install bearing retainer plate to hold bearing in
place. Install all three bearing retainer screws loosely, then torque 25 to 45 inch-pounds.
4. 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 tool C-3858. (Refer to Figure 24-20.)
—CAUTION—
Ensure bearing is installed squarely at installation or damage to
bearing will result. Press bearing on rotor shaft until bearing
contacts shoulder on rotor shaft fan hub.
5. Install the pulley on the rotor shaft. The rotor shaft must be supported in a manner which will direct all
the pressing force on the pulley hub and rotor shaft. (Refer to Figure 24-21.)
—NOTE—
Press the pulley onto the rotor shaft until pulley contacts inner
race of drive end bearing. Do not exceed 6800 pounds pressure.
Do not hammer.
6. Install the mica insulator on the heatsink mounting stud in the end shield.
7. Install the round plastic insulator, flat face up, in the battery stud hole in the end shield. (Refer to
Figure 24-22.)
8. Install the positive heatsink assembly by placing the battery terminal through the round plastic
insulator and the capacitor end over the heatsink mounting stud. Ensure the three rectifier straps are over the
studs on the terminal block. (Refer to Figure 24-23.)
9. Install the capacitor terminal over the heatsink stud and install the capacitor insulator making certain
the insulator seats properly in capacitor terminal and heatsink hole.
—NOTE—
Models with S/N PA-28R-7918001 thru 28R-8218017, the
capacitor is located on the aft alternator bracket per Piper Kit No.
764 372v. This kit when installed will provide improved service
life of the alternator bracketry and filter capacitor.
10. Secure the capacitor bracket to the end shield with attachment screw and torque screw 30 to 40 inch-
pounds.
11. Install the positive heatsink nut and lock washer and torque 20 to 30 inch-pounds. (Refer to Figure 24-
24.)
12. Turn end shield over and install round plastic insulator over the battery terminal with the flat side up.
Install nut and washer and torque 30 to 50 inch-pounds. (Refer to Figure 24-25.)
13. Slide the negative rectifier and heatsink assembly into place in the end shield with the three rectifier
straps on the terminal block studs.
