May 28, 20197 yr I am trying to replace the Mains Seals on a 2004 Rev3. I'm struggling with the Primary Drive end of the Crankshaft. Could someone clarify whether the nut is Right-Hand or Left-Hand thread. Any tips for getting it off (I don't have an impact wrench).
May 29, 20197 yr If you need to keep it from turning this will help. https://www.amazon.com/Motion-Pro-08-0427-Gear-Jammer/dp/B001AVS60O I have no experience with a 2004 but other years are all right hand threads.
May 30, 20197 yr Go here and look for the Trials Service Manuals at the bottom of the page. They are for newer bikes but they may give you some insight as Beta haven’t significantly changed their design for years. https://www.betausa.com/content/support
