I'm in the process of cleaning and lubricating a Myford Super 7 made in the early 1980s. The manual states the cone clutch should be lubricated as follows: "With the clutch disengaged apply two or three drops of oil weekly". However, it isn't obvious to me how to do this. Can anyone enlighten me?

You hold the clutch open [disengaged] and introduce the oil into the gap thus revealed on the rim of the brass cone.
I don't think oiling as frequently as Myford suggest is strictly necessary. I put a drop or two in mine years ago to correct snatch and squeal on engagement; instant cure and I haven't treated it since.

Mike open the side cover for the belt change, operation the clutch lever and you will see the centre part move in and out, when disengaged there is a small gap you can see -- a couple of drops of oil into the gap and give it a few moments to work its way down -- job done.

Brilliant! No more deafening squeal from the clutch. I was scared to use oil in the wrong place if there is friction material.
Many thanks chaps,

There's no friction material involved. It's just the angle of the taper that does the job, similarly principle to the Morse taper (which should also be lightly oiled).

When I bought a new Super 7 Plus some years ago it arrived with a faullt which made it unusable. The Myford engineer came to the house and after he'd fixed the problem (new mandrel) he gave me a runthrough on maintenance.
I expressed disbelief that the cone clutch needed lubricating but he insisted it was best given a drop of oil at fairly frequent intervals. As stated by others, with the clutch disengaged, put the oil in the gap between the coned faces.
