I know this isn't a direct answer to your question: but it's really alot
easier to pull the pistons, get them into the cylinders on a bench and then
install the two together.  I think pulling circlip's and piston pins much
easier than trying to push a cylinder down over a piston still attached to
the rod.  Use rags to clog the cylinder bores, do not want circlips flying
down into the block.. "would not be funny" -Ben
