hi,

 

does anyone know how to remove a crank case water jacket bolt thats been rounded out.

 

Cut the head off then screw a suitable nut down the thread followed by a 2nd nut dome up tight to the 1st nut. then undo with the spanner on the 1st nut which locks against the 2nd nut and will undo the bolt. Also handy for Removing studs.

Or if you want a handy workshop gadget then invest in a set of Irwin bolt grips.

the bolt is way down in the water jacket next to the piston chamber cant get down to the head of it.

The bolt grips in petes link fit onto a normal socket set extension bar .

Which will allow you to reach it think a set to suit the 12mm or 14 mm(can't remember the excat size of hand ) block bolts is about £25 on ebay [emoji6]
