this is a big job would require removal of sump opening of conrods(4)vernier gauge and measuring of big end itself almost certainly will require a new crankshaft as whilst the bearing will wear so too will the crank ,they are not a bearing in the true sense of the word theyre actually made of a white metal that is precisely measured and usually only go from lack of oil so most probably other engine problems really a big job they would come with standard size shells(as theyre called in trade)you need to figure what size you now need to account for wear on crank shaft aswell maintenanceserve@hotmail.com regards
