Did any of you find that your crank was machined a little bigger then normal cranks.. Did you have any problems with clearance?
The guy I buy my bearings from said that eagle cranks are machined on high limits so I should not run a standard bearing, he said that I should run a fedrual mogal .001" bearing to compinsate for the higher limits on the crank.. ?? is this true.. I have never heard of this..
I am trying to get a set of bearings.. it's either the Clevite "H" series ( bigger chamfer for aftermarket cranks) or the fedrual mogal ones he suggest. and my block is in the shop getting worked on so i can't really measure anything..
thanks

My Eagle crank had .0025 on the mains and .003 on the rods with standard bearings. It is brand new 4340 4.25 stroke. Some cranks are overmachined, that is why you see a lot of companies making the .001 tighter bearings. I would say that is not uncommon. What clearance did you end up with, the looser clearances won't hurt, if not extremely out, due to the severe nature of a boat motor.

I can't measure my block because its in the shop.. I think I will just end up getting a standard set and if they are to tight I can just buy a .001" set to give me some more clearance.. I stil have to do some checkin around..

Travis,
The only machining problems I had with the Eagle cranks where the radii on the rod bearing journals. The Clevite bearing with the bigger chamfer was still not enough to clear it. We ended up having Moldex fix them.
As far as the other machining tolerances I don't remember, I was just the assembly person , my friend was the one checking all that stuff. He's they guy that does it for a living not me.
I was at the cabin over the weekend, there is a ton of snow, we got at least 12" Saturday night.

Travis, I just completed my 383's that we spoke of before. I used H-beam rods, and Clevite race bearings with no clearance problems what so ever. The bearings are chamfered at the crank sides and fit fine. What rods are you using?
