Primary
Either a Monograde Oil, or (better) ATF Oil.
(I use Shell Donax TX)
As for the primary drive, oils have changed dramatically since the early seventies, and additives we used to put into our engine oil, like STP, are now already contained in most multigrade oils. These additives are molybdenum (graphite) based, and will give you clutch slip very quickly.
Friends from within the Lubricant industry, as well as Richard Negus, ex-Norton Motors "Chief of Motorcycles, and ex-owner & tuner of the most successful long distance racing Commandos, both confirm that, with the high temperatures combined with the high pressures in a roller-bearing engine, multigrade additives give up quickly and leave you with the base oil within as little as 600 miles- which means you 20W50 becomes 20 oil, which is not up to the job in a Commando engine used properly!

Perhaps 'forced HOT air breather' is a better related to your bike :idea:

needing said:bill said:the dexron friction improvers have NOTHING to do with bearings & bushings but the type of friction materiel used in the clutch plates. the type F was formulated way back when Ford used bronze clutch plates and was an old hot rodders trick with organic plates as it made the apply more aggressive. ATF has been in use in manual transmission for a while with the T5 being one of the first, one of the reasons was it used organic cone clutch's instead of brass balk rings in the syncro's. ]
Hi Bill.
"...NOTHING to do with bearings & bushings..." ?? Just how do bearings and bushes get lubricated inside an automatic transmission if not via the ATF? I am yet to see a grease gun taken to a transmission!
needing said:Hi Bill.
For the last time, I say again that I use ATF Type F in my bike's primary case as a chain lube that does not cause the clutch to slip in my experience of using it. I do not use ATF in my Commando gearbox or engine and cannot get a response what anyone actually does use and why. Whether ATF of any type as current Original Equipment (OE) car or bike recommended for gearboxes is irrelevant to me as this is the Norton Commando forum.

Excellent. I don't have a lathe but reckon if I did I would do what you have done! Also, can't help noticing you've made more than can possibly fit on one clutch. :idea:
