Problem with liner diameter

We have one case now where the liner after it was fit into the cylinder did not fit into the engine housing. Subsequently it had to be reduced to fit with a lathe or the opening had to be widened.

It seems RE does not produce uniform diameters with their engine blocs.

Obviously widening the opening is a much more involved process that may even require a disassembly of the engine to avoid metal residues getting inside - so it is recommended to avoid this by fitting the raw liner to the engine bloc once the cylinder is removed to check the diameter and if necessary use a lathe to fit it.

This should not be necessary in most cases but if it is it will be much easier to accomplish than the widening of the engine body.
