Thanks. I need to look into a decent set for my 350F.
Yes, it does look like the rear axle from this this bike. Cutting will be last resort. Hopefully heat and a slide hammer will work.Pete12 said:Wow, that looks suspiciously like a rear axle for the swing arm bolt. Regardless, do what Brodie suggested but if you don't have any luck there you will probably need to get a hacksaw blade between the swing arm and frame on both sides and cut the bolt off. You will then be able to push it out with a press.
Thanks, you read my mind. I have tried pressing the bolt out with M12 thread and a 12mm steel plate either side with a tube over the bolt head. Still no good. The next move is as per your suggestion with the bike on its side, tube over the bolt head and seated on the garage floor. Then the big hammer comes out.....XS750AU said:Hi Bernie
I have been thinking about your "issue". Short of cutting the bolt, there could be some hope using a modification to your earlier attempt using the home made "screw press".
The force from your screw press is just flexing the frame. If you can anchor to the opposite side of the frame and then you will eliminate any flexing and the force will go directly into the pivot bolt. You would also need to use a lot heavier cross brace than the 3mm angle (guess) that you used in your first attempt. You need to eliminate flex.
Second idea is lie the bike on it side. Use a piece of 30mm tube (or there abouts) that pivot bolt round head can slide through and long enough to bottom out on the frame pivot bracket and shed floor. The threaded end of the pivot bolt would be pointing up, and then hit it with a BBH using a soft drift. This method also eliminates flex.
Heat on the engine pivot area will help for both methods.
