    Hi first time person here.
    I’ve bought the above bike as a non runner. I’ve read that the auto oil lubrication is a bit hit and miss so it’s best to go back to a petrol oil mix. Has anyone on the forum done this and if so what type of oil and percentages and what’s the best way to blank off pipe work?
    Any one in the Kent area own one of these models?
    Regards Paul.

    1930 Super sport model 9 lubrication Empty Petroil

    Post  piston 197 on Mon Jul 15, 2019 5:31 pm

    You have read ( or been told wrong) you will not run the autolube engine on petrol/oil mix for long before your main bearings/ bushes are shot. Use the autolube system and do NOT blank of the pipes or it will end in tears.
    The autolube system feeds the oil into spirals in the crankcase bushes, it is oil in these grooves which lubricate the  bushes and form a crank case seal. Without oil in these bushes they will wear rapidly and the engine will be unable to start because of a poor seal and the crank will be moving about in the bushes giving a variable points gap.
    Providing the oilways are clear and there is a good vacuum seal on the oil tank cap the autolube system works fine.

    Oh and this topic would have been better placed in the  "Bike Help," category rather than in the "website" category where i found it by accident

    Hi JH.
    Thanks for information. Would you know what oil would be best?

    The system was designed to work with a straight grade SAE30 oil, the system is still as it was and best to stick to this

    I have a 1931 non-runner one of these, had it for years. Did you ever get yours running?

    Regards using the oil delivery type and premix.
    I had a very long discussion with someone on another site about this. I had been advised that you must not run the oil type with premix instead and he just would not have it.

    Regards the oils I had words with an oil company explaining what I run and they gave me The name of a product that is 40 grade mineral oil but has a few additives so as not to smoke and coke things up and should lubricate better, I have it in now and am slowly adjusting the oiler.

    1930 Super sport model 9 lubrication Empty oil mix v autolube

    Post  piston 197 on Wed May 27, 2020 12:53 pm

    That is correct, if you have the autolube system use it, as the oil is fed into the spiral grooves in the main bearing, both lubricating them and forming a crankcase seal.
    If you blank off the oil feeds and run on pre-mix only your bearings will have a very short life, you will lose your seal and soon it won't go !
    In short DO NOT DO IT !

    Ken

    A a matter of interest what was the product they recommended? It will be good to know how you get on with it.
    Cheers, Mark.

    This is what they said would be ideal.
    Although it says premix they said it would be fine being injected.
    I have opened  my oiler a fraction to make it just smoke but it's early days. My intention is to measure the oil and fuel and try to get 25:1
    It’s not so much the smoke as the carbon gunge the old stuff that is left in the engine I don’t like.
    Mind you after a ride On one of these your clothes stink of oil.

    This was its first run in over 50 years

    I too believe that autolube engines should not be used with petroil though I’ve recently come across this, I’m not sure where it came from as there’s no page header or footer to indicate it’s source, just a random couple of pages I picked up somewhere. As you can see the note suggests otherwise, I don’t think I would risk it myself though.

    Post  piston 197 on Wed May 27, 2020 8:27 pm

    I think what the book is trying to say is you cannot use the Petroil crankshaft in the auto-lube crancases, but you can use the Autolube crankshaft in the Petroil cases, rather than you can run the Aoutolube engine as a petroil type with the pipes blocked off ? while the conrods and piston are common to both

    How does the autolube work on these? Last time I looked at mine the pipes were loose so someone was tinkering with it prior to my ownership. I would like to run it autolube when I eventually get round to fixing it up.

    Post  piston 197 on Wed May 27, 2020 8:43 pm

    The oiltank is pressurised by the crankcase compression, this forces oil down the other pipe where it is fed into the main bearings.It is important to have a good seal on the oiltank cap so that the system pressurises, the feed is regulated by the screw on the oiler in the tank1930 Super sport model 9 lubrication Img_8013
    1930 Super sport model 9 lubrication Img_8014
    in the diagram you will see the porting holes in the autolube crankshaft that are not in the Petroil version which is why the cranks are not suitable to be run petroil

    get youself a copy of
    The villiers engine by BE Browning  ( the pics above come from a 1950 edition), these regularly turn up on ebay, i had a spare copy but sold it recently
    https://www.nortonownersclub.org/html/spareslist.php?t=Lightweight
    heres one a later 1955 edition, but do not pay that much for it !!!

    Very useful information, thanks John! My enthusiasm for this bike is re-kindled but it’s been standing for around 70 years so maybe the engine should be stripped rather than trying to start it as it is. It has good compression but no spark so a re-magnetising looks to be necessary.

    or probably a new/rewound ignition coil as well, these fail as they get old and internally crack
