[QUOTE="dustrat, post: 579174, member: 20238"] Yes it looks like your case has been line bored and depends by how much as what oversize bearing you need.The best thing you can do is buy crankcase and crank shaft gauges from JK or Heritage and measure your case. Also measure the thrust end of case to see if thrust has been fly cut.The standard size where thrust bearing sits is 22mm.Having cases line bored is quite common on older cases because of wear. I line bore and fly cut all engines that I build.When ordering new bearing you need to find out if crankshaft is standard or under size ie has it been reground , if case has been line bored and to what size and if crankshaft thrust has been cut. Type 1 Beetle is fitted with upright engine as are Early Bay campers meaning that they have fan housing. Later campers have type 4 engine that is flat with no fan housing as cooling is different.
