I fit my belt over the water pump and dynamo pulleys then push it over the crankshaft pulley whilst turning the engine over on the starting handle. I then put the handle between the dynamo and block to lever the dynamo out whilst I tighten the mounting bolts. I have also re tapped the threads on the water jacket to 3/8 unc and enlarged the dynamo holes so that the larger bolts are less likely to strip the threads.
See you at Gaydon and we can have a chat.

A few weeks before, I never heard from the Bearing boys, but because we are working now on a new machine in South Africa, we need them also for some modifications.
I know from the "B" version from the belts, there is one in the machine where my laptop is connected on ;)

I prefer the B33, with more adjustment space, and a little bit more work to mount than a B34.
Maybe I buy one when I am this afternoon in Johannesburg in the shop, I can use him when I am at home ;)

The dynamo pulley on George's car is the two piece non water pump fan blade type. The original water pump kit would have had a different dynamo pulley.
When I bought my car it had a water pump, fan blades still on the dynamo, no brass pipe and the water pump outlet plumbed in to the long bottom hose with a copper T piece.
