Step by step guide on how to install piston rings once the piston has been removed
from an automotive engine.
Difficulty Scale: 8 of 10
Step 1 - To replace piston rings the piston must
be removed from the engine block and replaced (if worn.) For best results the engine
block should be bored and new pistons fitted to the connecting rods which should
be re-sized. Piston rods can become "out of shape" due to the extreme force they
are subjected to. All piston rings are accompanied by a set of installation instructions,
these instructions are used to determine the orientation of the piston ring gap.
The location of this gap is an important aspect to the performance of the ring. Begin
by cleaning the piston thoroughly and securing it firmly in a vise. (Do not tighten
against piston, use connecting rod.)
