Ok so I can't get this bastard bolt out.
I've tried staring, swearing, turning, pushing, hitting and the f'ing thing won't budge. Any clues?
Looking at the parts list there appears to be pressed bearings, would that be right? If so how do I get them out?

Well it looks from cruising around everyone elses questions about this, gentle constant presure from like a G or F clamp or failing that a press.

I thought that answer sound familar!

And lots of WD40 or the likes soaked in overnite. [-o< [-o<

Ok this ain't funny anymore! I have tried a couple of clamps. Shit loads of WD40 aswell a few other things. Has anyone else had this bolt in place before? The bolt seems to be moving freely in the frame but jammed in the swing arm.

Had exact same problem!5LB lump hammer,flattened the bolt off-thing still wouldnt have it!
Take it to an enginnering shop,charged me £5 to have it removed.Then before you reintall,apply plenty of grease,to repeat-APPLY PLENTY OF GREASE.

the seized bolt will spin and maybe move in and out 2mm or so, but along the shaft suface corrosion has started and locked the bolt in between the set of needle roller bearings.

best of luck - take bare frame to somebody with a hydraulic press
(If you only wanted to service the back end this will be out of the question to strip the whole bike!)

IF you cant shift it quickly with a hammer - be patient and spray and soak and perhaps try heating and cooling (buy some assembly freeze spray in a can or dry ice etc) - bashing the end of the threads will distort the end and perhaps knacker them and the bolt

the other method ELF/MJ? used, was find a narrow alleyway and a hydraulic bottle jack

As said when you go to reinstall (as well for axles and any long bolts) coat the shaft with grease to stop any future corrosion - not the threads though.

INSTALL the pivot bolt from the right, with the threaded end finishing on the left side of bike, so less chance of rain water seeping along the bolt and rusting up in the bearings or along the shaft - if it was installed on right hand side (left to right) was probably the problem.

Thanks for that. I decided to hand her over to some "professionals". A friend works at a h***a dealer and it's down there now, waiting for a time when they are not "busy".
I never considered which side is should goback in from so very usefull tip, cheers.

Scissor jacks is there anything they can't do?

I forgot to mention the h***a tech moved the bolt about an inch then quit, decided it was to hard.

good lad =D>

Now I just need to figure how to get the sleeve and bearings out. Any suggestions?

Ok nevermind they're out
