Eagle crank bearings

[49-blues]

What would be the best bearings to use on a new eagle crank and K1 rods? Im thinking clevite ms-960s and clevites cb 1443p-would do you guys think?

I have somewhat of the same post in For engine builders. I was told only H series clevite bearings should be used because of the side champfers that the P series bearings do not have. Im building the same thing and would like to know whats been proven. Hopefully we'll both find something out.

same thing here

I used FM 107M's on the mains, and the "H" series on the rods. Everything worked out after much test fitting. I would make sure you have a set of std.'s and a set of .001's available in case you need to mis-match to get your clearances.

Even if you use the Clevite bearings on the rods, they must be machined for proper fit.

Nick- what part of the bearings usually need machining? The sides (width)? or the ends?

Is that with the K1 rods too? And also what does need to be machined?

The factory crank has rolled, undercut fillets while most race cranks have .125" radius fillets for added strength. You need to chamfer the bearings to clear this fillet. If the bearing makes contact with the fillet, it will keep oil from flowing out which in turn keeps new oil from flowing in. This will result in burned bearings.

The H series has thoes champfers. That was my quiestion. Are people using these with results?

What going on here? what part needs to be machined? The rods or bearings? Ive never herd of a bearing that needed ot be machined. Are you talking about the rods having to be machined?

Had rod bearings machined the first time, the second time I used a box cutter to chamfer the rod bearings (only needed one side of bearings chamfered with my setup). Looked and worked much better (with more bearing surface left) !!!

PS: The bearings are more even and the best part is that it only cost me some time and I know this sounds crude but the overall results were more even. :smile: And I used King bearings, rod & main.

Well H series clevite bearings are supposed to have that champfer already made into the part so hopefull that will solve that problem. Next issue is trying to find them????

This man may have a point?
