Does connecting rod orientation matter?
Does connecting rod orientation matter?
Orientation remains the same when installed correctly on the crankshaft. Every second rod journal faces in the opposite direction (180 degrees) on each crankshaft journal. The narrower sides on the rod journal face each other, the wider part of the journals face outwards towards the crankshaft journal.
Which way should the arrow point on a piston?
Arrow on piston should always point to the exhaust side.
How are the rods installed in a reverse rotation engine?
On a reverse-rotation engine (where the crank rotates counterclockwise when 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.
Which is the right side of a piston rod to use?
If the big end of the connecting rod features a larger chamfer on one side, this side must be installed facing the crankshaft’s journal radius fillet. If the rods are designed for use on a crank that does not feature a radiused fillet, the rods may not feature a large chamfer on one side.
How are the rods oriented on a crank?
If the rods are designed for use on a crank that does not feature a radiused fillet, the rods may not feature a large chamfer on one side. Rod orientation can then be obtained by orienting rod with its bearing tang grooves biased toward the pan rail (outside) or cam side (inside).
Why do you need a rod bearing on a piston?
rod bearings exist to facilitate bearing installation and are not specifically intended to prevent bearing “spin.” The bearing crush that is generated when the cap is properly tightened prevents bearing movement.

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.
