Why do Pistons have arrows on them?
Pistons always have directional arrows on them showing you which way to install them. The wrist pin is often offset to lessen piston side thrust to reduce wear.

What does the Arrow mean on an asymmetric piston?
Asymmetric pistons may also feature an arrow that indicates piston orientation relative to the front of the engine. This provides a handy visual aid in installing the pistons so that the major thrust side skirt faces the major thrust load within the cylinder bore.
Do you need to mark the orientation of a piston?
Most pistons will come with an arrow or some sort of marking to illustrate the required piston orientation, but it is always good to verify this information, especially if you are using an asymmetrical piston configuration. These marking can differ depending on the application, piston design, and installed orientation of the engine.
How do you replace a piston on a 4 stroke car?
Remove the head and place it aside, handling it carefully. Next, do the same for the cylinder bolts, and carefully remove the cylinder. As you remove the cylinder, the piston is going to stay on the connecting rod, so it helps to hold the connecting rod steady as you wiggle the cylinder off the piston.

How are pistons installed in a clockwise rotation engine?
viewed from the front of the engine), rods are installed similar to a clockwise rotation engine, where the larger chamfer side of the big end faces the fillet. However, if the pistons feature an offset pin, the piston must be installed “backwards” relative to installation in a clockwise engine.
What does the front of the engine mean on Wiseco Pistons?
Some Wiseco automotive pistons, such as the Sport Compact or LS series pistons, include a marking that indicates the front of the engine. The front of the engine typically means the cam chain or cam belt / water pump end of the engine.
