https://paypal.me/DonDyar?country.x=U... Watch me lap the right-hand main bearing on 1953 Harley Davidson K-Model engine cases using the Kent Moore HD factory lapping tool with full explanation of the lapping process starting with flat lapping a spacer and on to barrel lapping a bearing hole with the special factory tool, using this method is the only way to ensure the engine main bearing are in true alignment as per factory recommendations.
