Contents Product Affected • ISL G CM2180 Description of Change • New steel and aluminum piston kits have been released. • The new steel piston replaces the original aluminum piston for select ISL G CM2180 models. Reason for Change Improved piston durability. Customer Communication Customers who operate 320 hp engines may experience a reduction in power when cruising at high rpm. https://qsol.cummins.com/qs3/pubsys2/xml/en/tsb/2017/tsb170022.html 6/28/2017 Steel Piston and Aluminum Piston Kit Introduction Page 2 of 7 Service Instructions CAUTION Use of an aluminum piston engine control module (ECM ) calibration code in an engine with steel pistons will create an uncertified engine configuration and can result in inconsistent and undesirable engine behavior, and possible engine damage. NOTE: Some engines with specific control parts lists (CPL) are not able to be converted to steel pistons at this time and must continue to use aluminum pistons. Reference the Service Parts section below for more information. Warranty Considerations: For warrantable piston replacements requiring the upgrade of aluminum pistons to steel pistons, steel piston upgrade kit, Part Number 5406086, must be used. Installation of Aluminum Pistons: • See Table 1 for aluminum piston kit part number and kit contents. • See Table 4 for a list of CPLs that must use aluminum pistons. Conversion from Aluminum Pistons to Steel Pistons: • See Table 2 below for steel piston part numbers and steel piston upgrade kit contents. • See Steel Piston Installation Instruction, Bulletin 5414627, supplied with the steel piston upgrade kit. • See Table 3 for a list of CPLs that are required to use the steel piston upgrade kit when being converted from aluminum to steel pistons. • With the exception of the upper and lower gasket kits, all parts in the steel piston upgrade kit must be used during the conversion from aluminum pistons. Gaskets that are not required for the repair of the engine, such as the rear main seal may be discarded. • When changing from aluminum to steel pistons, an updated ECM calibration code must be installed. Reference Table 5 for ECM calibration code information. • When changing from aluminum to steel pistons, the CPL number will change. • Upon completion of the conversion from aluminum to steel pistons, an authorized change label, Part Number 5297400 must be completed and installed on the engine.

When upgrading to steel pistons, steel piston upgrade kit, Part Number 5406086, must be used. All other engine CPLs must use aluminum pistons. Reference Table 3 and Table 4. • Steel piston and aluminum piston part numbers are not to be mixed in the same engine.
