Wireless Set No. 52 Canadian - Project

[David Dunlop]

Unlike the grub screw on the Sender Blower fan, the one on the Supply Unit fan was well and truly seized in place.

Two days of soaking in sewing machine oil, lots of hand tapping on the fan hub with a suitable sized punch and I was able to pop the grub screw free and into about a one-quarter turn mode, back and forth. Another day of soaking and I was able to slowly work the grub screw back and forth more and more this morning until it came out of the hub completely.

A soak with Deoxit this time and I was able to drift the fan back and forth on the Blower Motor shaft to within an eighth of an inch of coming off completely. I then took an old, dull half-inch wood chisel, and with the blade resting on the shaft and the flat of the blade against the fan hub, I was able to tap the chisel head with a small hammer and pop the fan off its shaft.

This should make removal of the Blower Motor assembly from the Supply Unit a lot easier.
