Austin 7 Dynamator (accuspark.co.uk)
There's history on these.
Opinions differ about the basic item but when first launched the manufacturer supplied them with new gears that wore very rapidly, sending iron grindings around the engine and causing chaos and heartbreak. A forum search will tell all.
It is essential that this modern drive gear is replaced with an original Austin item. If you're not certain please check immediately . If it is a modern one you may need to take action to clean out the engine. Others have first hand advice

RE: What have you done today with your Austin Seven - sparkeysprite - 07-03-2021
Oh dear, I didn't know that so thanks for the advice. The unit was new and unused when I got the car so I assume it has the manufacturers drive gear on it - I'll have a look. I've only covered a few miles so I doubt there will be much wear so far.
RE: What have you done today with your Austin Seven - Mick Hobday - 07-03-2021
Steve,
That's a good looking Special. I agree with Tony, it's a nice change to see a properly road equipped special, rather than the usual Ulsteroids or cars with a very basic body and cycle wings.
The Austineers are listed here:
https://oldcarservices.co.uk/austin-seven-specialists/ as " Second-hand spares also restoration"
Austineers is a long established business dedicated to Austin 7s, based in Bradford on Avon and headed by Dave Williams. I tried to contact Dave a couple of weeks ago but I was unable to get an answer by phone and his website appears to have been recently taken down.
RE: What have you done today with your Austin Seven - AustinWood - 07-03-2021
Today I went to Tesco in Galashiels for the first time for a few months. Took the Austin, which is what I usually use for local running around.
On the way back a core plug blew out on the way home and filled the car with steam. Very spectacular. I carry a few spares including a core plug so not a great problem. That's only the 3rd core plug in 50 years. and only the 2nd time this car has stopped on me in 30,000 miles.
Must change the other plugs now. The one that failed had rusted through.

I fitted a new brake master cylinder today. Having bought a cylinder and fitted it last week it took me a while to work out why the brakes didn't work. Wrong size of piston/cylinder, it was for a clutch and only 5/8" rather than 3/4" doh! Stupid boy..
I got a 7/8" instead as the 3/4" was only just up to the job. Seems to be OK

Thus if there is a leak just use JB weld to cover over.....no more rust!........did this on very inaccessible back of my Scimitar V6 block that would have otherwise meant engine out.

Had a run out in the RP to see a pal of mine. Got stuck behind a coal lorry of all things. Very rare round here despite the coal mining heritage of this area.
RE: What have you done today with your Austin Seven - John Mason - 09-03-2021
Today I have been a complete idiot and buggered up one of the exhaust manifold threads for the stud. I attempted to helicoil it and made a right pigs ear of it. I have helicoiled in the past and found it relatively easy so I don’t know what went wrong. I do know however that is now beyond a repair by yours truly so the block will have to come off and a trip to a professional engineering workshop is needed together with the embarrassment of telling them what I had done.
