14 Check the crankshaft endfloat with a feeler gauge or a dial indicator as described in Section 12. The endfloat should be correct if the crankshaft thrust faces aren't worn or damaged and new thrustwashers have been installed.

21 Pistons/connecting rods

- refitting

1 Before installing the piston/connecting rod assemblies, the cylinder walls must be perfectly clean, the top edge of each cylinder must be chamfered, and the crankshaft must be in place.

2 Remove the cap from the end of the number one connecting rod (refer to the marks made during removal). Remove the original bearing shells and wipe the bearing surfaces of the connecting rod and cap with a clean, lint-free cloth. They must be kept spotlessly clean.

3 Clean the back side of the new upper bearing shell, then lay it in place in the connecting rod. Make sure the tab on the bearing fits into the recess in the rod so the oil holes line up (see illustration). Don't hammer the bearing insertinto place and be very careful not to nick or gouge the bearing face.

4 Clean the back side of the other bearing shell and install it in the rod cap. Again, make sure the tab on the bearing fits into the recess
