Hi Radzziu
Some years ago I made new timing gear pinions for my B29 and got raw pinions (imperial dimensions) from HPC Gears and I think they have pinions that will fit T6 also.
A friend of mine made a new and more stable anchor plate for T6, that is fixed to all four bolts and send me a sketch also showing the distance between centers for timing gears. I made then a drawing for my own T6 and got a sligthly different result for this distance.
I try to attach a photo of the situation in my T6 engine and the sketch and drawing mentioned.
Hope this informations can help you.
Regards hoejmark

Hello all,

Fist time post here, I am currently mechanically restoring a 1927 EW350 for a customer of mine and we are missing all the drive parts, gears and clutch between the magneto and the generator including the gear on the generator. I do have the generator and generator specific front timing cover.

Like most of these projects the bike was stripped apart in the last 4 or 5 decades and things have gone wondering!

Any help in finding the missing parts is greatly appreciated.

Cheers
Frank @ Llama Engineering NZ

The Manual for a T6 etc doesn't help ?

Measurements are unlikely, unless on a blueprint.
Does anyone hold such things, that far back ?
Can recall when BSA closed, it was said that 20 tons of documents went into a skip !

Measuring YOUR engine and making to suit should be adequate ?
What you have don't look too bad ??
You wouldn't be the 1st person to hunt down a spare engine to obtain such things ...

That finned alloy sump is a true work of casting genius.  !

Would the timing gears from a 1918 2 3/4 fit?
