Pivot stuck :|

Boxing · Guru

Hi.

I'm stripping my DT down to repray it, but the pivot bolt just will not budge, tried taking the weight off of the back wheel and still nothing. Sprayed it in WD 40, and still solid like it's welded on. :|

Absolute pain in the backside, don't really want to damage the bushes or anything like that getting it off.

Also, whacked it with a hammer a few times, still won't budge. Completely jammed.

Anyone else had this problem? If so what's the best solution here? smile

Thanks for all replies and advice in advance.

Only way you'll get that out, is to put a 1.5mm cutting disc on a grinderette, and chop it out, being careful, and taking your time you can get in between the swingarm and the engine mounting first, then both ends, you might need more than one disc too.

Or heating the surroumding area and having a bash.

MDK · DTR Legend

get a good strong steel rod or massive screw drive down the hold and bash the fcker out ..

had loads that have been stuck but never had to cut one usualy with a bit of brut force they come out ..

try getting some on to sit on the bike bouncing up and down as you try to remove it

slob · Guru

As MDK says, Perfect if you can get an old punch and jam the taper in the hole ect. Don't be afraid to give it a good smashing.

Probably worth mentioning you undo the nut so that it sits on yhe end of the thread. So you dont mess up the thread.

Its getting it moving thats the problem.

You should be using lots of wd. Then using the nut as the hitting point move the pivolt bolt. Once successful spray more wd on the areas where its stuck. Knock the bolt back the other way. Apply more wd. Knock it back again. Apply wd. Repeat until it becomes increasingly easier to move.

Well, update for those interested. Took the bike to a mechanic it was booked in since the day this thread was opened up.

His going to get the pivot off for me, then I'll get it home and drop the engine out and begin on the rest of the frame.

I masked the back end off and took the grinder with a wire brush attachment and took it down to bare metal.

Some right idiot has owned this bike. Someone's reprayed over rust with black paint. :| I pulled off the top layer of paint to find more rust underneath.

Anyway will be all sorted. Doing it the cheaper way by doing it myself. If it gets rusty again I'll go down the powder-coating route.

Also this is going to be a slow on-going project. I'm doing what I can whilst I have a bit of money, then it'll be a running project. Looking into a supermoto conversion, which will happen at some point. Once I've got the supermoto conversion done I'll start spending money on cosmetic parts like new handlebars and finally get that short clutch lever I've been after for ages. :3

Also, anyone know how to get them stickers off the tank? I have a odd tank from a different blue model. I want to respray it black to match the bike.

NEV · Guru

Hair dryer usually gets the stickers off, hairspray gets the sticky residue off

What supermoto setup you looking for. The ol excel rim route?

What colour is the swing arm going?
