Hi All,
A question regarding the 'Lucas' indicators as used on all 1970's British bikes.
What do owners do to stop the chrome bodies partially rotating on the stalks? Stems are screwed into the body really tight, (well, as tight as I dare go without breaking them) but the bodies turn a small amount clockwise or anticlockwise when riding. Isn't enough to make them useless, but enough to notice that they look 'wonky' when you stop. I guess they are turning by the amount of clearance between the nut inside the body and the body itself.
Araldite, JB Weld or similar around the nut? Fit non-Lucas Indicators?
Your thoughts appreciated.
Regards,
George

Movement of the indicator…
Movement of the indicator body relative to the stem occurs if there is clearance between the anti-rotation flats on the stem and the body. The movement can be prevented by removing the stem nut and locking washer, and simply inserting material to take up the clearance, then refitting the washer and nut.

Movement of indicator
As above where I have found a spring washer seems to keep them tight. This is on a T120R 72 OiF Triumph where there is considerable vibration through the rear support bracket. Trust helps, Hugh

Earthing?
Bear in mind when fiddling with these things that chromed plastic is not the best for getting an earth from the lamp holder back to the bike/frame. These days of Thin Wall cable helps no end. 16/020 0.5mm will do the job nicely. The earth being soldered to the lamp holder. This then allows one to insulate the lamp-holder with a rubber washer. Useful on the pre Commando frame.

I mount them so when 'pointing down' they are really horizontal, they rarely if ever then decide to point upwards.
