HITACHI Electronic Ignition: Overhaul: Reassembly

Reassemble distributor in reverse order of disassembly. Install weight spring with longest, free length to shorter hole side of timing lever. When installing rotor assembly, match notch in pick-up coil base with groove end of housing.
When installing vacuum controller, tighten only the screw holding the controller to the housing. Tighten screw between lever and pickup coil base when installing pick-up coil.
When installing pick-up coil, adjust air gap to specifications. Position rotor shaft so flat side is centered on pole piece of pick-up coil. See Fig 1.
Align match mark "A" on pinion gear with right side of notch "B" on lower end of housing. See Fig 1. After assembly, check centrifugal advance by using a distributor tester.
