Piston Designs

So many designs, so little time
By Steve Scott

One design fits all? Maybe, but certainly not very often where heavy-duty diesel pistons are concerned. Piston designs have changed in recent years and the design you take out of an engine may not look like the new replacement. If it does not, you certainly need to confirm the replacement is correct before going further with a rebuild. Even greater attention should be applied where the thought of mixing different design pistons within an engine are involved.
