Cam shaft installation

[Stretch]

I am finally getting around to assembling the engine for the 2010 diesel crawler loader.
I cleaned the block and oil passages. I have installed new cam bearings. I have installed the lifters.
When I installed the cam shaft it was extremly tight. After I bolted the thrust plate down it took a great deal of strength to rotate the cam.
I pulled the cam back out and chamfered the edges of the bearings. The shaft was still tight.
I ended up lapping the #1 bearing a bit and the shaft got easier to rotate.
I still believe it is to tight though. I haven't measured the bore or journals yet, that will be tomorrow. Of all the engines I have put together in my life I have never had a cam shaft this tight.
The question I have is, Years ago I remember having to hone bearings for the proper clearance on some older equipment. Is this one of those that you have to hone?
Thanks in advance.

Are you sure the cam is straight?

Not 100%. When I pulled it out on tear down I didn't have any issues.
I will chuck it up on my lathe and put a dial indicator to it to check it.

Stretch,
Pretty sure you should not have to hone those bushings. Any chance you have the bushing slightly cocked, or maybe dinged an edge?

I ended up using a dial bore gage and measured each cam bearing. They were all within .003 to .0045. That is enough for oil. I did chamfer the leading edge of each bearing in case it got dinged when I installed them. I also noticed a couple of shiny spots on the no.1 bearing so I used 1500 paper and polished.
I slipped the cam back in and it turns much better but is still a little tight. Not near as bad as it had been. I believe I can live with it the way it is now.
Only problem now is that I was sent the wrong main bearings.
The box is correct but what's inside is not. Unless I am only suppose to use 3 mains.
I'm not sure, but what was in the box I swear is for a 2 cylinder.
Oh well, the saga continues.
