Wanted A10 crank
« on: 02.02. 2012 16:12 »
Hi
I am new to the forum, and i don't own an a7 or a10, But i have owned and worked on many classic and vintage british bikes.
Recently a friend of my fathers bought an A10 gold flash off a popular internet auction site, unseen. My father phoned me and told me his friend was having difficulty getting the bike going because it was tight to kick over. So i went to have a look, and to cut a long story short, i realised it was the timing side bush, so took the engine out and back to my place to rebuild. I stripped the engine and found nothing wrong apart from the bush. It had new pistons, rings, rebore, big end shells, and valves. I turned a new phosphur bronze bush and proceeded to build the engine up. When i refitted the barrels i turned it over by hand and thought, that's wierd the pistons were 1/4" from the top of the bores. Guess what, its got an A7 crank.
So i am on the look out for a decent A10 crank, if anyone in the uk can help out, please let me know.
thanks in advance
steve

 G'day Steve, welcome to the forum.
                                                 Shame about that, after all your work. A member or two here have had the same problem. If the budget allows try to find a large journal crank & rods.
Cheers

Cheers,
I just can't understand why someone would spend all that money on new pistons, rings, rebore, big ends, bush etc etc, and then build it up with the wrong crank.
It's a small journal a7 crank at the moment, with decent a10 rods, so to save him a bit of money a small journal a10 crank would be better, i should be able to use the same rods, just with new shells depending on the grind.
