What have you done today with your Austin Seven
How is the outer bush of the dynamo? If it’s worn, that happens.

Thanks for your replies. 

The dynamo gear is original and looks good. The bush on the dynamo end is a little bit loose (you can feel it). I would be happy to accept this as the sole reason except that I travelled thousands of miles on the bosch distributor that was in the car for the previous 8 years. I removed the bosch for performance reasons despite it being ok otherwise. 

Does anyone sell the oilite bush for the dynamo?

What is the best replacement gear? The current one is steel, but the gear on my old bosch is bronze or something similar. 

I’ll reveal the supplier of the gear once I have had the opportunity to contact them.

Having bent some 65 windscreen frames for RM and RN cars over the last 30 years so when I received a phone call for one I ordered the material and proceeded to bend it. It bent very easily and on removing the die found it had split, so I ordered another piece. I carried on with another job wondering what to do, if I silver soldered it I would end up filling the seal channel with silver solder, what to fill the channel with. Eureka, fire cement, it worked a treat, I cleaned it up and bent the other corner with the same result. I can only conclude that the material condition is different and will have to anneal the material before bending something I've never had to do. Only problem is when it gets hot enough to anneal it will be like a 5' length of spaghetti.

Peter,

I had two of these fail in a similar way on a rebuilt distributor, one after a few hundred miles, the second after just 12 miles. They were supplied new but were mild steel not hardened - worth checking on yours.

I have since re-fitted an original and have had no problems since. The supplier was unhelpful.

Peter.

On a replacement C35A dynamo that I bought some years ago, which was sold as "new old stock", the dynamo end bush gave out. Whoever it was that built the dynamo had pressed the end bush into the housing with the lubrication hole offset so no oil could get to it. No wonder it gave out. A replacement bush did the trick, but it's worth noting that they DO need some oil from time to time. On some dynamos that means prising out the plug. There should be a felt pad inside to hold the lubricant.

Sorry I haven’t been around for a while, after what seems a lifetime running my own business, I’ve retired at last closed down the business and returned to the Isle of Wight.
Health and safety officers can look away now!
I booked a van with a tail lift to pick up my Austin and other workshop equipment, lathe etc and with the ferry booked, the van turned up and it was a high bodied Luton...with no chance of changing the van, we had to get creative in order to load it...anyway it’s home now and I’ve already started to put it back together!

I'm not even going to ask how you got the back end on...

With the tail lift on the floor I guess.

Not today but over the weekend I put the engine back in, with a new alloy sump and standard number of clutch springs.The clutch is now operable without needing legs like a power lifter! I didn't need to adjust the pedal so I didn't get to test out my bolt on the end of the shaft trick (but if I hadn't done that mod of course I WOULD have had to adjust it).

I also fitted the new DD inlet manifold which suits my carb exactly so now I can start looking at how to do the exhaust. I also bolted all the accessories on, starter, dynamo, distributor and everything will fit under the bonnet. Handy!

I do need to order some bolts and things, longer ones for the sump, and also the 8 bolts that hold the hardy spicer prop shaft in. I know they are 5/16ths but can someone please tell me the length? I am not home to check. I think it will be 3/4 or 1 inch long? And I am guessing it's best to use nylock nuts?
