Rear shock removal

[Petey_h]

Hi,

I am a newbie here, and being vertically challenged, am trying to swap the springs on my shocks for the hyperpro ones. However, I have failed at the first hurdle - I can't get the lower shock bolt undone. I have broken two torx bits, have now tried heat, and extra leverage, and for my efforts now have a chewed up bolt. For my next trick, I am going to remove the rear arm, complete with shock. I think my best option is going to be a second hand arm, but unless I can somehow remove the bolt, I am also going to need a rear shock as well. Unless anyone has any brilliant ideas, or suggestions of good engineering firms who might be able to remove the bolt, for less than the cost of second replacements.

Thanks,

Pete

well you have learned the hard way that most critical bolts on a bm need heat at the first attempt and a good fitting tool to undo,second hand arms and a new bolt from bm is the easiest way to go i reckon but im sure someone will cone along with another idea.

I couldn't get mine of at first but I lifted the rear wheel slightly using a block of wood and the bolt came out with a bit of effort, my thinking was the block took a bit of pressure/weight of the shock/bolt area, hope you get it sorted

i've not had to use heat to get that bolt out on a few of bikes i've done. in fact, i'm not at all sure how you would get any significant amount of heat into a sunken bolt in a giant ali heat sink

Stripping out the bolt head suggests the wrong size torx bit was used. Get it right & they are tougher than ordinary hex socket heads.

Must have been bad luck or a badly fitting torx. My 4 shock bolts came out OK 2 weeks ago. No heat. No excess leverage. Just a wee squirt of plus gas. 2006 GS

Unlike some car wheel bolts the following day that needed a HUGE extra lever on the socket to break most of the bolts. And as for wheels stuck on hub spigots

remove the shock/arm and take it to a local engineering company they should be able to remove the bolt.the bolt is fitted with threadlock and will need heat to remove.i would probably weld a bolt to the damaged fastener to get it out.this could damage the paint on the arm but i cannot see it coming out any other way.pm me if you cant find any one to tackle it.mike

Thanks Mikeyboy - I may well take you up on that. As a 'fixer of 1200 final drives' is there anything I should do whilst I have mine off the bike? The bike has 55k miles on it. I will check for play in the bearings, but I did notice some swarf on the speedo pickup (I think that's what is anyway lol).

 

[mikeyboy]

excessive metal swarf on the abs sensor is not good,drain the fd oil. if is really black and burnt ,the pinion bearing may be worn.
