Alternator & Regulator: Overhaul: Reassembly

To assemble, reverse disassembly procedure. Solder rectifier leads as quickly as possible to prevent damage to diodes. When installing rotor assembly in rear housing, hold brushes in position by inserting a wire into access hole of rear housing. Remove brush retaining wire after assembly.
On diesel engine alternators, install vacuum pump vanes with rounded edges outward. Install housing and push it toward rotor before tightening bolts. See Fig 1. Lubricate pump before operating alternator.
