Going through and replacing an ignition switch on the '74. While in there i figured i would lube the assy. Currently the column lock will not "release" into the column to lock it.
Upon inspection the "cylinder" side will not retract back towards the key when the key is removed thereby not allowing the guide pin and column lock to drop into the lock position. With a little nudge the tumbler will retract but not unaided. Is this a symptom of a worn key or key wafers?

First, pull the key switch out via the small hole on the housing. Clean everything you can without taking it apart. Dunk the switch in some lacquer thinner, MEK, acetone, etc to dissolve the old grease. Rinse it with really hot water. Use a little spray, dry silicone to relube it.

Already pulled all the wafers and cleaned each as well as each wafer slot in the cylinder. The problem seems to be 50% worn key. Using the older rarely used Porsche key pulled in all the wafers better and 50% not enough oomph in the ignition switch key spring that presses the tongue of the cylinder back towards the key. I always thought the switch only had a radial spring to release the key from the "crank" position. It also has an axial spring to aid in returning the cylinder back towards the key. Thx. The Preferred brand of that type of lube? |

I have steering locks, and can fix your ignition for a minimal cost.
