Sorry for asking stupid questions, but I just would like to know will it be ok to purchase this crank and get the undersized bearings for it.
My guess is the 0.010" under Eagle crank was either damaged or was machined wrong and needed corrected, or something along those lines. The crank manufacturers always shoot for a standard journal diameter unless you order one up different for some reason.
Just looked at that crank- says "recommended up to 0 HP". LOL
Personally I wouldn't be buying an Eagle crank in the first place. I've never had a problem w/them- but then again they were checked over before being used. I've also had no real problems using OEM cranks, within their limits.
Chances are it'll be fine, you'll get one less rebuild out of it down the road. If that is a fair trade to you for the money saved (how much are you saving?) then go for it. But ultimately, whether you buy this undersized crank is up to YOU.
