Hello, I ordered a set of ACL main bearings but I noticed when they came that only 5 have a center oiling groove. The OEM bearings have center grooves and holes on both sides of the bearing but these only one. Does this matter or did I get the wrong item or should I buy different bearings? They came like this:

Thank you

 

oil is only fed via 1 hole to the crank (the top) per bearing

also those are Kings not ACL bearings.

 

x2 to what s2000ellier said as far as oil channel for the bearing.

I would still run OEM bearings if it were me though. I currently run ACL bearings but after the first time around, my next Honda rebuild will be using OEM bearings. I say that purely on the fact that you can adjust tolerances by slipping in different sized bearings according to the level of uniformity you're comfortable with (without filing down bearings).

 

Appreciate the input. At this point, I'm using what I have. I understand the OEM stuff might be better, but im just going to go with these anyway. New ACL should be better than used oem right? I understand the picture is of Kings bearings haha I do indeed have ACL the picture was just for reference to show an example of what I was talking about. Basically then, from my understanding of what you said, put the grooved bearings in the block side(top) and the solid bearings in the cap side?

 

yep
