Move the Piston to the bottom of stroke and mark the connecting rod cap for position, and remove the connecting rod cap bolts. Remove the connecting rod cap the lower connecting Rod Bearing then remove the upper Piston connecting Rod Bearing and ridge ream the cylinder wall. Carefully handle the Piston to prevent cuts from worn Piston rings, then discard the Piston and, with the help of a Piston Ring expander tool, expand and remove the Piston rings. Remove Piston pin from the Piston and connecting rod assembly and disassemble the Piston and the connecting rod using Piston pin remover/installer set (J 24086-B). For installation, position the notch on the Piston and connecting rod, install the Piston pin guide, apply clean oil to the Piston pin, and install it into the Piston and connecting rod by means of the Piston pin remover/installer set (J 24086-B). Choose new Piston rings, take the Piston Ring gap with a feeler gage, and file off unnecessary material. Test the Piston Ring side clearance and use various pistons rings if the fit is not to standards. Mount the Piston oil ring, expander, and the second oil ring followed by the second and top compression pistons using a Piston Ring expander without the need to tighten unnecessary expansion. Stagger the Piston oil rings, oil ring rail gaps, and compression ring with respect to the notch on the Piston. Lubricate the cylinder wall and Piston rings with clean engine oil, then install the Piston using a ring compressor and wood handle, with the lower connecting rod end without damaging the crankshaft journal.
