Removing suspension bolt

[martinh]

Hi Guys. How do I remove the bolt in the picture. I have taken out the screw that keeps the two bolts together, but cant seem to push the bolts out. I used a thin piece of wood, but if I knock it in it just comes out the other end without pushing the bolt through.

 

I would like to clean in between the bolts and the link.

i dont know that particular setup or bike but would suspect the shock is putting pressure on the bolt, try removing the shock first to lessen the pressure and the use a bolt or something similar in size to the one you are trying to remove to push it out, you may need to find a rubber mallet and gently tap to get it out. just dont use too much force as this will cause other issues

Are you sure there are no circlips holding the bolt in place?

Its a BMC Fourstroke 29.

 

I don't know if there are any circlips behind the bolts. I can't see any.

based on the 4stroke shock bolt for 2008 - 2009 models, i think you just need some percussive persuasion to get it out..

i doubt the bolt design will have changed much. tap from the side where the nut can be removed.

The bigger the problem the bigger the hammer......

Cool thanks Capricorn.

 

Unrelated: where can I get Loctite Blue. I keep taking out bolts and never replacing them properly with Loctite.

Go to Midas and ask for it - they sell it in small quantities - not locktite brand, but a LOT cheaper - and the big Loctite bottles go off after a while.

try local auto parts store. they normally stock loctite blue.

I would remove the one bolt and size it up. Then insert a longer, same size (M6 probably) bolt into the bar. This way you can knock it out without damaging the bolt which you are going to ultimately use again...

Once you get a bit of corrosion around the bolt they can be pretty difficult to get out. Helps to have a drift of the right size and extra hands to hold the frame. The worst I've seen came out with a terrible scream and a bit of persuasion from a 16 tonne hydraulic press. No damage to the carbon frame but the mechanic was sweating somewhat.
