Considering dynamo belt conversion

[duTch]

 Last time I did it, I packed under the sprocket diametrically with flats & wedges, and gave the loosened nut on the spindle a whack- may need a bit of heat (after packing & wedging), or even a tap on one side of the sprocket to whack it cock-eyed...

Thanks again lads.
Got it off without any damage to it.
I held the pressure on with a 2 arm puller and at the same time tapped it a few times with a hammer and it popped off.

Be careful hitting the shaft as it is pressed on to the gear (67-335) and its easy to knock the shaft through the gear a bit causes all sorts of problems . Been there done that   
I have drilled an taped two holes in the sprocket to attach a puller so as not to have this problem.

 I think that's the reasoning behind my suggestion, but forgot that bit thanks Pete
  Good idea about the puller holes

I tapped on the side of the pulley, not the shaft itself.
Thanks for that anyway, I didn't know about that.

What is the standard size sprocket on the E3L dynamo ?
I have two E3L dynamos, one has 13 teeth and the other has 11 teeth. 

[duTch]

 If you plan to use one, would be best to use the 11T anyway- better ratio (I think that's what should be, but why bother with the 13T)

Hi Roy, same for A Group 1958-59 models and 1960-62 models. See no 44 in 1958-59 diagram.

Yes, 11 T is the correct one.

I am not reusing them, I am in the process of fitting a DRL belt drive.

Hi Roy,
The 13 tooth sprocket is from the C10/11 single models as far as I know

The 13 tooth was used on the E3H short generator on the A7 as well as the C10/11.

[RoyC]

All fitted.

[RogerSB]

Looks good .

Mine should be on soon
