I am trying to remove the swingarm assembly to change bushing etc. However, please refer to attached pic, I cannot remove item #25 (where the pointer is). This is a "T" shaped bolt that goes through the lower shock mounting. The other side has a bolt (#26) also and a clamp that holds a drain hose. I have tried just about everything I can think of. I used penetrating fluid, tried heating it up with propane torch and hitting or using penetrating fluid. I cannot move this one. I have screwed the bolt back in from the other side and tried hitting it....managed to damage head of this bolt. Removed it again and put in a narrow punch to bottom out in the threaded area. Hit this quite hard but cannot shake this loose. Is there a trick here? Or am I going about this the wrong way? If I can't get it out, I will have to put bike on a lift of some sort, and then remove the center stand to get the #14 area to swing down to replace bushings etc. I will not be able to put in grease zerks unless I can get it off the bike. Thanks all.

The April/May edition of Machinist's Workshop did a test of penetrating oils where they measured the force required to loosen rusty test devices. Buy the issue if you want to see how they did the test. The results reported were interesting. The lower the number of pounds the better. Penetrating oil .. Average load .. Price per fluid ounce None ................. 516 pounds .. WD-40 .............. 238 pounds .. $0.25 PB Blaster ......... 214 pounds .. $0.35 Liquid Wrench ... 127 pounds .. $0.21 Kano Kroil ......... 106 pounds .. $0.75 ATF-Acetone mix.. 53 pounds .. $0.10 The ATF-Acetone mix was a 50/50 mix (1 to 1 ratio).
