Why I don't miss building motors sometimes.

[wsuwrhr]

Well....I am still fighting putting the iron motor together.
Now I only have .002 across the rod caps and .0015 up and down.
I measured the rod bore at 2.4995 at 45 deg and 2.500 up and down.
The crank is dead nuts standard/standard at 2.3750.
The bearing shells measure .0615-.0624.
If the crank and rods are standard, I guess that means the bearings are overcoated. WTF? What else could be wrong?
Will I ever get to boat again?

Clevite 77 bearings, stock rods, stock crank.
Got to be the bearings right?

you may have to mix and match bearing sets to get the clearance you are looking for.
like different top and bottom halves with different clearances. make sense?

Crystal clear,
Unfortunately the bearings are all the same.

they come in different sizes...

Good luck with a phone contact for Dana, Clevite, Mahle or anyone else who may have bought the company.
I think I am just going to go sell all my shit and stick with crotch rockets. So much less of a pain in the ass.

Add an X to the end of the part number of the mains or rods for an extra .001" of clearance.

I was able to get a tech number for Clevite from Summit.
I did find out about the X number, but that will only give me .0014 clearance.
Subract the bearing shells from the rod diameter, subtract the crank, the number left is pretty small.
Am I being too smart for my own good? The dork from Summit told me to put it together with Plastiguage and call it good. "It is more accurate that way."
I'm thinking at the point I need to have the rods resized.
Clevite tech just called.....I'll be back.

I am just going to buy the x part number and see where that gets me.

right?
Anyone need a set of standard HP bearings for a 440?

If you are getting your measurement by "doing the math", install the bearings, torque the bolts, and use a mic and dial bore gauge to find out the true clearance. It will be different than measureing shell thickness, etc.....
