When I contacted Draganfly Motorcycles asking if they had the Tool/Spanner p/n 61-3003 (as per that tool shown on the diagram) they said "no, that spanner is too small to fit the bottom fork plug..."
I am very much afraid that it is Draganfly that have got it wrong. This is what BSA service sheet No706 list as the tools required for telescopic fork dismantling, 'A', 'B', 'M' group, and C10, C11G, and C12 models.
61-3001 fork top nut spanner
61-3003 fork plug spanner61-3005 oil seal holder assembly tool
61-3006 oil seal extractor
61-3007 oil seal assemly tool
61-3350 fork leg assembly and removal tool.
The service sheet says this: Grip the shaft in a vice using soft jaw clamps on the unground portion of the shaft and unscrew the gland nut (f) Fig X4
Service tool 61-3003 is designed for this purpose.
Quite clearly Draganfly have no idea what they are talking about!
