Changing the piston

[ThunderCody]

Which direction does the arrow on top of the piston point to, the exhaust or the intake?
or does it matter?

You want to put the ring retainer pins on opposite sides of the intake port!

 

[ThunderCody]

The pins are already on the piston. which way does the arrow go towards the intake or the exhaust?

 

[Street Ryderz]

The pins are on the intake side regardless of the arrow direction

 

[ThunderCody]

so do I point the arrows towards the intake or the exhaust?

Ok thanks.

 

[ThunderCody]

I dont see any pins but I guess I will point the arrow towards the exhaust then is that correct?

Sorry Im asking for a friend who is putting this together. I appreciate your patients man.
He is saying he doesnt see any pins????

I think what Street Ryderz is saying is that
Different engines can have different markings on the piston so the arrow is unreliable as a guide for ALL engines. So the arrow can help you see at a glance which way to put the piston ONLY once you know which way the arrow faces on YOUR engine.
The pins (or the ring gaps) are ALWAYS supposed to be on the intake side.

The pins are in the ring grooves and are obviously where the ring gap has to be.
That is why the ends of the rings have a circular shape to fit around the round pins.

The pins and ring gaps face the intake port so you can ignore the "arrow."

If the "arrow" is actually a triangle it points to the intake.
An actual arrow marking with a shaft points to the exhaust.
