ACL Bearings with a hole?

[BBMonte]

I just got my ACL Bearings in PN: 8B743P-10 , now the rod Bearings have a notch out of the one side, when u put them to gather thay makes a circle with the 2 hafts it is on the opposite side of the locking tabs. what is this for ? My old ones didn’t have that hole in them? I am running Eagle "SIR" 5140 Forged I-beam Connecting Rods P/N: ESP-6135P can I run them with that hole in there? Or shud I get some different ones?

if ou are saying that you have one hole at the bottom 1/2 of the bearing that is ok .this would be a H bearing setup for a alum rods with a hole in the shell they will work fine in a steel rod engine

no it looks like this it makes the hole where the 2 hafs come togather

that is no big deal they will be ok

[pat mccarthy]

this is a H bearing cut for a large radii they will have a Upper and Lower bearing half make sure you put them in rigth they will have upper or just a U on the inside of the bearing and the lower or just L if this crank has a large radii

ummm ok? but what is the hole for?

ummm ok? but what is the hole for?

looks? it will not hurt any thing . if they line up you are good some of the old rod s had this and the rod was cut thru rod cap and the rod to spray oil on the cam this part of the bearing has nothing to do with how it will perform in you engine

[BBMonte]

if that is the case i kind of think it might help by pooling up oil in that little hole when the crank oling holes line up

[pat mccarthy]

you are not pooling that much oil a very small amount it is not any thing to worry about

[BBMonte]

well thanks for the info ill just stick with them

Pooling is good for retention. Go with Pat on this. Older rods had the matching slot for this app. It won't hurt a thing and the reciprocating assembly doesn't care whether or not that it has it.

what do u guys think of ACL Bearings anyways i know it is to late i have them but are thay any good?

[pat mccarthy]
