Which way do my Pistons go?

The DI piston shows the forward facing directional arrow while the standard 4-valve piston shows which side should be positioned towards the exhaust valves. In any type of high-horsepower and/or high-RPM application, piston-to-valve clearance is critical.

What happens if you put a piston in the wrong way?

-the valves may be bent, and may break (they are 2 piece valves) This will wreck cylinder, piston and head, maybe more. Has happened before.

Where should the piston arrow point?

The arrow should be pointed “up” (towards the center of the engine) if the arrow is orthogonal to the pin bore, or towards the front of the engine if it's parallel to the pin bore.

Are Pistons directional?

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.

Which side is the thrust side of a piston?

When the crankshaft rotation is clockwise, the left side of the cylinder liner is called the thrust side (TS) and the opposite side is known as the anti-thrust side (ATS). Piston impacts can occur on either side of the liner.

What does the number on a piston mean?

53.94 is the piston size in millimetres (diameter) This is the exact size. KZ engine pistons, unlike some other engine types, are stamped with their exact size rather than under or over sized, like an Iame KA100 for example.

What does ex mean on piston?

Also known as Explosion Proof, Explosion Protected, Ex Proof, Ex Rated – used worldwide as simple ways to say, “explosion resistance.” Sometimes you may also see 'flame proof,' though that term is a bit misleading.

What is piston offset?

Piston pin offset refers to the piston wrist pin being a bit offset to one side of the piston i.e. for it to not be in the centre of the piston.
