Cummins Sulfur Tolerance Kit For Off-Highway Engines (49-675 hp

Product catalog summary

Availability and Restrictions:
Cummins Sulfur Tolerance Kits are available for engines ranging from 49 hp to 675 hp, including Tier 4 Interim and Tier 4 Final engines. These kits require the destruction or return of existing emissions dataplates, which are replaced after installation. Once installed, engines cannot be reverted to their original state. Kits are available through Cummins Care and must be installed by a global Cummins distributor, as conversion is prohibited by the EPA within the United States.

Purpose and Benefits:
The Sulfur Tolerance Kit is designed for Tier 4 or Stage IIIB/IV engines to operate on high-sulfur diesel fuel (up to 5,000 ppm), which is necessary in regions lacking Ultra-Low Sulfur Diesel (ULSD). This conversion ensures reliable performance and increases the marketability and resale value of equipment in areas without ULSD access.

Installation Procedures:
Installation varies by engine model and may include:

Exhaust Gas Recirculation (EGR) removal
Aftertreatment system removal
Installation of block-off plates and plugs
Exhaust manifold, intake, and coolant cover plate installation
Rerouting of coolant plumbing
Exhaust restrictor plate installation
New engine calibration to disable EGR and aftertreatment functions
Non-emissionized dataplate installation

Note: Replacement muffler is not included.

Contact Information:
For more information, U.S. customers can contact Cummins Care at 1-800-CUMMINS™. European customers can call 00-8000-286-6467. Additional details are available through local Cummins distributors.
