I have just read the thread and also fitted an E3L on my B. I did not use the tapered spacer shown next to the dynamo in the photo. I machined a parallel spacer, thick washer, to set the drive sprocket in the correct position. The main problem I found was the setting the clearance between the back of the oil spinner and the "top hat" which was bonded in to the case. It all went together, just. I have been told there is no need to "seal" the spacer to case. The only time I ran like this, too much oil came out. Always "sealed" it since. Just my experience. Not sure what, if any difference there is between a B and later castings in that area of the spacer.Thanks for the parts diagram. So far as I can tell, I have all of the parts shown in the diagram. I have attached a picture of what I have and my parts look identical to the diagram you provided. Hence I don't understand why it won't fit.

Without the PD32 adapter, with a modified bearing retainer and some spacers behind the PD33 adapter I was able to get the generator to fit well. I have now ridden the bike with the Lucas fitted and it does seem to do better than the Miller did.
What were you hoping to achieve? I understand the Lucas produces a few more watts compared to the Miller in use so will help to keep the battery topped up more readily. The major issue under "normal" loads, as I understand it, is the output at lower revs, ie low speed town riding with lights on. If you have a magneto it's less of an issue than using coil set up etc.

"What were you hoping to achieve?" - What I was hoping to achieve was a reliable working generator.
My Miller generator has worked well for many years/miles but recently quit as the result of water damage. I already had the Lucas and thought it was a simple substitution. I have a magneto ignition but here it is a legal requirement that a motorcycle has a lit headlight at all times - hence if you want to ride further than a charged battery will last, a working generator is mandatory.
