Ignition System: Overhaul: Reassembly
- Install centrifugal advance weights and springs. Install thrust plate and 2 washers on shaft. Grease shaft and install in housing. Put 2 washers and gear on lower end of shaft. Line up holes in gear shoulder with hole in shaft. Drive in new roll pin.
- Rotate gear until mark on gear shoulder lines up with mark on housing. Hold gear in line with mark and install rotor shaft on top of main shaft. Flat surface should face vacuum advance side of housing.
- Ensure holes in rotor shaft arms fit over pins in centrifugal advance weights. Install screw with lock washer in top of shaft.
- Align breaker plate in distributor housing. See Fig 1. Check that upper plate moves freely. Be sure diaphragm arm attachment pin does not rotate past end of slot in lower plate.
- If such condition exists, adjust range of free travel by forcibly rotating plate past its limit in opposite direction. Recheck pin position. When installing reluctor, drive roll pin in place with its gap away from distributor shaft.
- Check reluctor-to-stator air gap and rotor-to-terminal surfaces. Install diaphragm assembly. Crank engine until No. 1 piston is at TDC. Position rotor 1/8 turn past firing position for No. 1 cylinder (mark on distributor).
- Install new "O" ring on distributor housing. Line up mark on distributor gear shoulder with mark on housing. Insert distributor straight into final position. Rotor will turn itself to No. 1 firing position.
- Install hold-down bolt, and tighten it temporarily. Set ignition timing, and tighten hold-down bolt securely. Install distributor cap, aligning mark on cap (near clamp lug) with rotor.
