Whether there are now bearings available to the aftermarket I'm not sure, but I just had a look on Ford Etis and there is this note on the 1.7 Puma VCT engine page.
NOTE: Do not dismantle the crank gear.
The bearing clearances and bearing shells have very fine tolerances, as a result of which the crank gear components cannot be renewed individually. It is not possible to measure the main bearing clearance using conventional methods.
The crankshaft has eight counterbalances and runs on five bearings.
The lower crankcase provides significant additional strength for the cylinder block.
Surely if there is that much end float (2-3mm) the block and crank with be scrap?
Stock spec for end float on these - 0.22-0.43mm
