Cat 3500 Marine Emissions Upgrade Kits

Posted on August 15, 2011

Caterpillar Marine Power Systems and Caterpillar Emissions Solutions have announced that the United States Environmental Protection Agency (EPA) has certified Cat 3500 Series marine emissions kits according to EPA Rule 40 CFR Part 1042. This Marine Remanufacture Program applies to many commercial engines flagged or registered in the United States, and the requirements include a 25 percent particulate matter reduction at overhaul.

The kits include a list of primary components; electronic controls, camshafts, cylinder heads, flywheel housing, air lines, engine oil lines, fuel injection lines, turbocharger oil lines, water lines, exhaust manifolds, aftercooler, valve mechanism, pistons, turbocharger shield, turbochargers, wiring groups, fuel injectors, and exhaust heat shields.

Emissions upgrade kits for Cat 3500 Series marine propulsion engines are currently available for order from Caterpillar. The kits are also available internationally for customers but compliance will depend on local acceptance, Cat said. Cat Marine said customers should contact the local Cat Dealer to determine applicability based on existing engine serial number and operation profile.
