• At 61 kg this needs lifting gear and cannot be handled by one person
• Confirm the engine is the TAMD74A AUX build with double starter motors, as the outlet arrangement is what separates this housing
• Renew the rear seal and housing gasket while the housing is off, and check the flywheel ring gear teeth
