GENERAL
When disassembling parts that are duplicated in
the engine, (e.g.: pistons, connecting rods etc.), it
is strongly recommended to note their position
(cylinder 1, 2 or 3) and to keep them as a “group”.
If you find a defective component, it would be
much easier to find the cause of the failure within
the group of parts (e.g.: you found a worn valve
guide. A bent spring could be the cause and it will
be easy to know which one among the springs is
the cause to replace it if you grouped them at dis-
assembly). Besides, since used parts have
matched together during the engine operation,
they will keep their matched fit when you reas-
semble them together within their “group”.
