Does anyone know what the "special" grease used on cam disc of a Hoover
Keymatic washing machine timer is?

Electrical stuff like switches usually uses Silicone grease for its
insulation properties, though for this application there are no contacts
near the cams so car grease would probably do.

Are you resroring this as a musium piece, or (dare I ask), is this machine
still in use?

The machine is in regular use, it was built to last! The timer is
dismantled for repair at the moment.

And why not. 1970s?

I've not seen the mechas on those from the inside, but as someone else
said if its non-electrical then any grease will do. If theres electrics
there, use only petroleum grease. Other greases become corrosive when
electricity is applied.

If it's 'just' a cam with no electrical contacts to be lubricated, the
search CPC.co.uk for plastic grease, used on videos and is available in
small quantities

Mine is also in use since circa 1993, but the timing is getting erratic
due to wear on the cams. Sometimes filling up and pumping out overlap a
bit.

The machine is a 1975 Keymatic, and is in almost daily use, it's
predecessor, a 1962 Keymatic, I still have.

The switch levers in contact with the grease are "live", I have tried
clear silicone grease in the past but it creeps and contaminates the
switch contacts. The original grease is a white dry lubricant/paste,
I have never been able to find anything like it. I thought of trying
some white PTFE spray grease, or a compound containing molybdenum, but
dont know if these are suitable for electrical contact?

If you could post a well lit detailed pic, that would help. Awkward
cases will often have some workaround that involves a minor mod and
solves the problem.

I wouldnt use anything but petroleum on live electrics. You can thicken
it up with zinc oxide powder, but of course that wont raise its mp any.

Didnt know keymatics went as far back as 62.

Sounds a bit like the Finish Line grease used in bicycle wheel
bearings. It's a synthetic grease packed with micron teflon
particles. I've used it on a number of things quite successfully,
having bought a large tub which would outlast my bicycle use by
a few lifetimes. (I've subsequently seen it in small tubes;-)

I remember neighbours having one in 65. Great machine it was - and
solidly made.

Pay no attention to that man behind the curtain.

I've taken a couple of good pics, but not sure how to post them? the
help says something about sending them to your group's e-mail address?

Not sure what thats about, as usenet is text only. You can put them on
free site space, eg photobucket.
