Abstract

PURPOSE:To reduce the man-hour required for assembling and machining a crank case for an internal combustion engine of the type having an ignition coil in the crank case, by forming a work hole for fastening an ignition coil in the wall of the crank case at the portion thereof facing an ignition coil fixing hole. CONSTITUTION:In machining and assembling a crank case 1, case members 1a- 1c after casting are at first coupled together by used of knock pins 1b1, 1c1, and then bearing holes 1a2-1c2 for supporting a crank shaft are machined. In carrying out the above operation, the position where an ignition coil 3 is to be located is determined by use of a work hole 1c3, and a threaded hole 1b3 for fixing the ignition coil 3 is machined also by use of the work hole 1c3. Then, disassembling of the case members 1a-1c, coupling of the case members 1a-1c to the crank shaft, installation of a magnet rotor 2 and the ignition coil 3, etc. are carried out successively. Thereafter, machining and assembling of the crank case 1 is completed by fastening a screw 4 through the work hole 1c3 and confirming an air gap D.
