Does anyone know what dia & thread bolts I need for the flywheel on my Deutz 1011 engine, I am assuming it will be a fine thread .

Have they an odd number of bolts? I think M12 x 1.0 but I can’t remember if they are torx, Allen hex or hex head bolts!

Thanks Mick. There are 8 bolts not sure if they should be torx ,allen or hex head but can’t see any reason not to use ordinary hex bolts as there seems to be plenty of space around them.

Sorry I think that is the2011 bolts, 1011 are there 8 bolts? and they are spaced differently, for balance, I think they may be M12 x 1.0, trying to remember, are they 15mm hex bolts?

Deutz recommend new bolts, 30nm + 60deg + 30deg so I guess maybe stretch bolts hence they thrown away!

Does the flywheel locate on a peg or dowl? M10 x 1.0 could be right!
