Came off early DG. 1985

be careful they are helicoiled as standard so the drill may snag, You could try some heat and a punch to see if they rotate.

I have seen the bolts sieze into the cradle and thats maybe why they have been snapped when somebosy tried to remove the cradle, I can't see why they would sieze into the engine with helicoils.

I always use loads of copper grease on the bolts on assembly because they are a good few inches in the cradle and you get bimetallic corrosion between steel and aluminium.

And adding copper to the mix, trimetallic corrosion? Use graphite grease maybe?

maybe but experience tells me copper grease works

Engine run with the cradle bolts loose = fatigue failure of bolts.

You'd think it would crack the bosses in the engine case but apparently not.

Are they barstewards to drill out? Or same as exhausts studs only bigger. I can do an exhaust stud, start to tapped thread, in 30 minutes now. Plenty of practice recently.

A very pleasing start to the day. Soaked overnight in Plusgas. One sharpened punch and very oversized club hammer, and out they came. Twenty minute job.
Itchy..you are an outstanding individual... thanks for the tip
