engine stand so assembly is upright and flywheel shafts
are horizontal.
2. Carefully slide flywheel assembly out of left crankcase and
place it in a clean safe place.
3. Unbolt left crankcase half from stand and move it to bench

crankcase half facing upward, position crankshaft bearing
bore over support tube.
6. Use a suitable drift punch to tap oil seal from crankcase
