Timing gears

[Radzziu]

Hi Does anyone have a diagram or drawing showing the engine gear hole spacing for a T6? Is there a workshop manual or any other book that can help rebuild a Douglas T6? The club doesn't have one.
I making all new timing gears for my engine and be good to have any helpful diagram 
Regards

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.  !

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
