hi all iv just brought some yb pistons and rods but they dont have what number cylinder its ment for is this a big problem ?

 

used pistons ?? numbers are only used as reference so they can be replaced in the correct cylinder of the engine they were removed from, also big end caps are given numbers, so they are re-assembled on the correct rod, if say the engine was stripped down on a bench, to be rebuilt, ,
new/used pistons have an arrow on them also, this points towards front of engine

 

oh thanks mate
