Ignition System - HITACHI Electronic: Overhaul: Reassembly
- Install oil seal, bearing, and thrust plate in housing. Lubricate shaft with molybdenum disulfide and install in housing. Install rotor and turn it so that it faces No. 1 cylinder mark on cap. See Fig 1.
- Install thrust washer and coupling on shaft. Check that rotor is still pointing toward No. 1 cylinder mark on cap, then align index mark on coupling with index mark on housing. Install roll pin and pin retainer.
- Align breaker plate in distributor housing. See Fig 2. Check that breaker plate moves freely. Be sure diaphragm arm attachment pin does not rotate past end of slot in lower plate.
- If it does, adjust range of free travel by forcibly rotating plate past its limit in opposite direction. Recheck pin position. Install reluctor with manufacturing code facing up. Install roll pin with its gap away from distributor shaft.
- Check reluctor-to-stator air gap. Install diaphragm assembly. Crank engine until No. 1 piston is at TDC of compression stroke. Install a new "O" ring on distributor housing.
- Install distributor, making sure that lugs engage in camshaft groove. Install hold-down bolt. Install distributor cap and spark plug wires. Connect wiring and vacuum hoses. Start engine and adjust ignition timing.
