[Heathkit] HW100 final load cap

[Dick KF4NS]

Yep, that was it. The reading is now .0014 ohms.I did manage to get
the oil (SB Blaster) out of the between section bushings but then the
shaft REALLY tightened up. I did not clean the front bearing of any
lubricants, so I proceeded to apply contact cleaner to it followed by
a squirt of liquid wrench L3 which is a penetrant/lubricant. It seemed
to free up a bit but stiffened right up again. Wish there was a way to
spin the pulley for a period of time but can't because of the stops on
the cap.

If there was ever a need for dial string design, this would be the it,
or better, a direct shaft connection. The belt is as tight as it can
be and is fairly new. It must be the original grease that has
hardened. I am thinking of applying heat to the shaft to try to
extricate some of that old grease. Running out of ideas here.

: Check the continuity between the shaft and frame while you rotate
it!
