the careful application of heat,preferably from a heat gun/hair dryer alternatively propane...keep it away from all things flammable like fuel and battery drain tubes,anything rubber,plastic et.c |

that and a torque wrench for a longer lever should do the job. G. |

Have you tried an impact wrench or impact driver on it? The hammering movement of an impact wrench usually helps where brute force fails. |

Hi Nnnnnnorman , If you can turn that bolt but its still stuck its probly rotating the lower eye bush in the shock , if you cant turn it its probly stuck in the ally casting , which is better , but either way I would try to remove the shock and the bottom link together and move it all to the work bench,. Once you have figured where it seized ( bottom eye or the casting ) and have properly supported the bit you will probly have to drive it out with a hammer and punch, a press would be better but...... . If its anything like my swingarm pivot bolt  . When you reassemble the thing , smear a bit of copperslip , or some anti seizure compound ( the lid was stuck on mine  ) to make things easy in the future. There is every chance that your the 1st person to try to remove this bolt . If the swing arm is also seized the 4 bushes in the little pic that I have arrowed are the most likley , especially the inner bush for the 2 needle berrings on the left side , to sieze onto the pivot shaft. If they do seize you will see that the pivot shaft will rotate freely with any bush its siezed to , so turning it wont help . I wound up lying the bike on its left side , with the frame around the swing arm pivot supported , and bashed it out with a log splitter. good luck Nnnnnorman

yes. success. after a bit of heat a lot of spray and plenty of club hammer the lower shock bolt is out. it took a long breaker bar to get it moving in the alloy sleaves and a good thumping from the hammer to free it from the central 'collet'? it was corroded into. copper slip for re assembly. now all i have to do is rebuild the unit before it goes back in. thanks for the advice guys.

thanks. on closer inspection the top eye of the shock is cracking. should i weld or replace this part or start looking for a new unit alltogether?
