I am doing a engine out of frame overhaul, #6 needed a sleeve installed, I sent the block to our local cat dealer to have the work done, I also had them install the cam bearings. I was just about to start putting the engine together and noticed that the only cam bearing lined up with to oil hole was #1, and the other bearings the oil hole is to the top @ 12:00 o' clock I looked in the manual and it says there right. So my question is, is this right and if so how do the bearings get lubed. Thanks

The bearings have a groove around the outside that aligns with the oil passage in the block.

Thanks for the reply that what I had thought, but when looking at the bearing oil hole I could not see the grove, so I got a small zip tie and was able to get under the bearing there is a grove. I just wanted to be sure. This is a great way to get good info. fast. Thanks again.
