GSXR 750 Swingarm Removal

[HughiusMaximus]

Evening.

Looking for some guidance on a L0 GSXR750 swing arm removal please.

I loosened the nut on the rear dogleg strut but the bolt doesn't want to come out.
When I turn the left hand side the bolt just spins.
I have given it a tap with a rubber mallet but didnt want to go nuts till I knew it was the right thing to do and didnt want to damage the bearings in the dog leg.
Also access is tricky as the exhaust pipework is kind of in the way....



Side views for reference..






Any advice welcome please.

It's probably the bolt has seized in the bushing. Turning the bolt then turns the bushing inside the bearing.

Remove the bolt at the other end of the dog bones along with the lower shock mount. That way you can get the swinging arm out to the bench and properly support it to press/drive out the bolt.

Good call thanks.

I'll give it a go tomorrow.

Progress.. had to undo the top shock nut and drop it all out as one in the end...

It looks like the bolt has seized to the bushing which is annoying...

Anyone have any words of wisdom before I start swinging a hammer at?

I have tried penetrating oil and a blow torch to heat it.. next step is probably to heat it for even longer..

Got it.. and mullered a needle bearing in the process.

Bolt was bone dry and corroded.

The epic saga of the incompetent mechanic vs GSXR 750 swing arm continues...

You would've needed new bearings anyway so all is not lost.
You gave it a successful battering

Don't worry about it, they all do that (GSXR's) . If you want it all fresh and working properly it needs stripped down every couple of years at least, cleaned and greased. Maybe worse up here in Scotland with the amount of salt on the roads at times but that worked for me and a mate with ours. Still do it even if your bike goes into a dealer for servicing, that's one job i have seen missed more than once on others bikes, and from different dealers despite the box being ticked on the service form and what prompted us to do it ourselves.
