This is what he sent back so if you Know what he is on about can you have anther look at the sprocket please to give him the more info.
Hi, You have not said what chain pitch you have but I assume it is 530. The 4 mounting bolt holes distance apart (known as the p.c.d.) is taken from the centres of the bolt holes.
I make it 74mm centre hole as there is nothing listed with 73.7mm. The p.c.d. at 110mm with 10mm bolt holes.
Is the sprocket flat on both sides or a recessed ring on the inner face? I think it might be 280 sprocket type but I now need to check to see if this is still available.
May be simpler if I donate my used one to you to give him. Just pay postage.
