Ignition System - HEI (Federal): Overhaul: Reassembly

Reverse disassembly procedures, while noting the following: Ensure there is special silicone lubricant between module and distributor base to provide heat transfer for module cooling. Lubricate felt washer with a few drops of engine oil.
After installation of distributor shaft, rotate to check for even clearance between external timer core teeth and internal pole piece teeth. The notch on the side of the rotor must engage the tab on the cam weight base.
