Herbie, Do you have a service manual? I got mine on Ebay and it tells me how to split the case. I didnĀ“t try it because it recommends a special tool. My mechanic said he could do it without the tool, but it looks like a bear to tackle it. If you are desperate I could probably scan the couple pages out of my manual and send it to you. Let me know via email. Cheers, Ben
