I checked the torque on my engine bolts over the weekend (and just now checked the parts fiche)
Front bolt is through engine with nut at the other end Rear bolt has no nut but should have a washer and then and bolts into the thread inside the frame lug. |

Hmmm, a timely reminder that I should really have a look at my engine bolts by now.
A regreasing, and/or a change to stainless seems to be in order. So I guess that's crash bungs as well, maybe. Any excuse for a mod. Good luck with the hammers. |

Still refusing to budge- so two options left- heat the block a few times with the ATF mix after, repeat a few times, and if that fails, then just remove the barrels in situ and paint the block in situ as well. Not ideal, but not much choice..

Ok, so I can't seem to be able to get a blowtorch into where I want it as there's too much other stuff there that can be damaged. So I might want to paint the block in situ- which I guess would involve removing the swing arm to get to the back and supporting the rear of the frame on a large block. At the mo' the swing arm is part drifted out and on a paddock stand and the engine is on wood blocks. It's all very greasy and dirty though and I'm not happy that it will be easy to clean and strip off being down on the floor in my garage. I have a dodgy knee so can't spend much time that far down nowadays..
Any advice?

Googling around, it seems that the acetic acid in white vinegar is a solvent for oxides of zinc.
Presumably its the swollen corrosion of the zinc plating that's causing the problem. I'm guessing you've perhaps already tried this, but I thought it worth a mention just in case. I assume you're also familiar with those plumber's heat proof mats. |

I think I've spotted the problem. How big is your hammer. Whatever the answer, you need a bigger one

I was wondering if you could lay the whole thing on its side and let gravity assist the flow of vinegar, possibly over a few days......?
Maybe even attack it from both sides. And/or even........take a deep breath.....drill a hole or two laterally in the crankcases to get the vinegar in to the central area ? I reckon if you rebuild it with the bolt still stuck it'll stay stuck. |

That bolt has to come out. Its a necessity. Started so needs finishing properly. Drill the bolt sticking out through and the nut if not threaded into the frame drift punch if you can the bolt back and fro to start the corrosion loosening. mainly the threaded end but not too much to avoid spreading

I did think of that but am worried by two thing- first, the bolt heads- I'm worried about drilling into the frame by accident. Ok, I could shear them on purpose as the bolt heads move a few degrees, but I'm scared to do that in case I CAN'T get the remaining bolt parts out. Secondly, the rear bolt is threaded into the frame I believe so that in itself can cause problems I'm sure as I don't want to mess with the frame.
