PROBLEM

Show/hide table

Certain C32 Petroleum Engines were shipped with reduced or necked down exhaust pipes to increase exhaust back pressure. There is now a washer available to weld into the inlet of the diesel oxidation catalyst. These washers need to be added and the exhaust pipes removed to provide a more robust solution to increasing exhaust back pressure.
