Hi Robert.

From looking on the net it seems the SC12 is basically a modernised Mk12. I have a very old Villiers manual for the Mk12 series which you are very welcome to have, its a bit tatty but readable. I think from what I have read that your SC12 might have electronic ignition, so I don’t know if it will help you. Are you going to Stanfield next Sunday? If so I can bring it for you.

Well, after a lot of swearing, use of Fox wedges and pry bars, I have managed to remove the PTO dog clutch cover. Then all the balls fell out of the bearing!
Mmmm. Well it needed replacing anyway.
Just need to pull the dog from the shaft now.
Next I have to remove the bolts securing the gearbox to the differential casing?
Any help/advice on completely stripping the drive train will be greatly appreciated.

Thanks.

Silverfox.

Fingers crossed for dry weather from now until the day! Can’t wait to get the machines well warmed up with a bit of work!

I had a very interesting meeting at Malvern with a Mr Mansley who was the son of the inventor, hos cousin still runs Gregson and Monk who made the machines in Preston although they have now diversified. I wonder if they could still make spares? He showed me photos of the prototypes and variations including a twin head version for cultivating either side of strawberry plants.

Hi Andy, The weight was on the outside of the flywheel, when I first saw it I thought it was the cover to allow access to the points. It had a spring that was pushing on a screw that seemed to serve no purpose.
The running of the machine is a mystery. The machine runs like on tick over and the speed improves very little when I open the throttle, I have no book for this engine, looks like the 147cc and I first set the points at 3/16″ TDC but changed to 1/8″ because of backfires and I couldn’t start it. I would be happy if the throttle made a noticeable difference.

Hi
The key will have to be machined (filed) to a boot shape as the keyway on the flywheel is only about 3/16 deep I will post a few photos when completed I have another 16h that has never been used it is a bit older than the one I am working on at the moment.it may have a differant magneto and set up I will see, just don’t want to open it up whilst the workshop is so full
Thanks for the intreast and information.

General view seems to be that we try for a repeat with some new machines at Newbury in October if you would like to take part please let me know. thanks

I’m having the same problem, tried in IE, Firefox and Chrome, it tells me there are forms below but there are no links becoming active anywhere.

Hello Dave.

Thanks for your kind offer, but, I have a copy of the spare parts manual.
The drawings don’t really give much information on stripping sequence.
I will have another try tonight.

Good morning all.

Well, the engine is complete. Only the cowling requires sandblasting and painting.
I am now starting to investigate to reduction and differential gearboxes.
However. The cover on the reduction gearbox is reluctant to come off.
Can anyone advise me of the stripping sequence for the gearboxes?
At first glance everything looks in fair condition. But only a complete strip and inspection will reveal the true state of things.

Thanks

SILVERFOX.

Thank for the reply
That was my first thought but the shaft seems cleen no scores or bruses. The flywheel bore also looks cleen I will get my camera out and take a few better photographs the present ones are a not so clear.

Is there a chance that someone has fitted a short key which has sheared off?
