Rod bearing tang towards intake or exhaust?
or does it matter?
Sitting at work thinking about it right now. I've assembled my rods and pistons, but didn't pay attention to the above mentioned.

the bearings fit the rod one way but the piston must face a certain direction and can be put on the rod the wrong way

BUMP this back from the dead.
I know the rod's bearing tang faces the exhaust side, but there are two tangs. One on the rod and one on the rod cap. Does the cap tang face the same way? Or is it opposite?

Re: Rod bearing tang towards intake or exhaust?
The reason I ask why is cuz I took apart a 98 gsr second owner of the motor was stock at that, tangs were on the intake side

Re: Rod bearing tang towards intake or exhaust?
glad this is back up. good info. (although no one as actually said a specific reason why, other than that's how it's designed) just in the middle of my D16 build and followed a b-series guide that said tangs to the Ex.

I don't think it really matters if it would go on the intake side or exhaust side, but exhaust side is simply Honda (maybe even industry?) standard. The tangs only really act to locate and center the bearing in the cap and rod bores.

Re: Rod bearing tang towards intake or exhaust?
what i was saying was i took apart a gsr motor that was not touched by any 1 and found the tangs on the intake side. does it matter or not, i know all the tangs have to be on the same side but does it really matter intake or exhaust

Re: Rod bearing tang towards intake or exhaust?
i think the dilemma is that you can assemble the rod to the piston 2 ways, but the piston should go into the bore only 1 way because the valve reliefs should match the proper valves. because of this, it is EASILY possible to have the bearing tangs facing the wrong direction. i still don't know why it is the wrong direction, it might have something to do with the oiling holes lining up properly with the oiling holes on the crankshaft.

Re: Rod bearing tang towards intake or exhaust?
No where in the helms does it state the tang has to be on the exhaust side. It merely mentions that the tangs on the rod cap and rod itself must matchup

Re: Rod bearing tang towards intake or exhaust?
ok so by this logic the tangs would have to point to the exhaust side, just took a look at the oiling hole on one of my stock LS rods, oddly enough though, my crower rods do not have this oil hole, nor do they have an oiling hole in the bearing area.

Re: Rod bearing tang towards intake or exhaust?
Yeah for oem stuff ok, but aftermarket? I'm going to redo my pistons so they are correct but Id really like to know the engineering reason behind it.
