Main crank bearings

Hi,

I'm having a similar conundrum to my big-end bearing selection. A 2.0 CF2 crank and conrods are going into a CF3 engine...

Bearings from the CF3 are P/N 46452266, which has been replaced by 71728317 (SP1,839-1,843). If anything these are a little loose in the block and the caps.

Bearings from the CF2 are P/N 7782622 for the 4 outside ones, and 46434100 for #3 (the one with the end-float bearings). I can't find either of these on ePer, and I've no idea what size they are. They look slightly bigger than the 464's though.

I've test-fitted the new crank with both sets, and it turns nicely with no play. To my eye/ear the CF2 778's are smoother, but then they are much less worn.

Any suggestions about what I should fit as replacements???

Cheers,

Iain
