Eventual was able to open up the the case . The sprag clutch I bought off Ebay is incorrect the part shown on Hitchcocks stated part number 560011 , the one I bought on Ebay said it was a direct replacement for 560011 ? However I think the original part number should be #15 560042 it's held in with a circlip . Thanks for all your help guys .
Go back to my Reply #10 in this thread where I pointed out the Ebay part might not be correct. It was only one piece of the total sprag clutch.
Click on the link in my Reply #10. Part #14 in that exploded view is what you needed. Part #10 is what you got off Ebay & is only part of the whole AVL sprag clutch.
Hitchcocks is a bit confusing now, I think. If you search on 560042 you don't get the correct sprag clutch for the AVL.
Good luck with it. I'm gonna pull my old invoices later & I'll see exactly the Part # I ordered & see what I get when I search on that number.
