Removing Main Engine Bolt
 

Hi there,

Well I am currently fitting some R and G crash protectors to my 2001 SV650.

3 Bolts have to come out, the two rear ones which thread into the engine I was worried about, I snapped the front version of this the other week and it had to be drilled out. Anyhow, I got these two out no bother with a bit of plus gas.

The main engine bolt that goes right through the middle won't budge. I tried using plus gas on it but no joy. The nut just won't loosen up!

I've left it soaking overnight but does anyone have any tips or pointers for me?

It shouldnt really matter if this one snaps because you can just push it out with the replacement bar, but I can't get it to move at all!

playdough has worked wonders with moving 14yr old seized bolts on my project.

Make a cup shape and stick it around the bolt....fill with plus gas and leave to work its way in overnight. Made things move like they weren't even done up.

Just be careful with the rear bolts! Soak them before even trying to undo them. If you snap one of them it's a major hassle!
