Engine News, SEBD9995, 26 June 2015, "Improved Heavy Duty Tier 3 and Tier 4 Injectors Are Now Used on Certain Engines". Disregard the previous article. The article that follows has added part numbers.

Description of Change: The improved fuel injectors have a tighter clearance between the plunger and body to reduce fuel dilution.

Adaptable To: The improvement has been made to the fuel injectors listed in Table 1.

The fuel injectors are adaptable to the above engines back to first production.

ReferenceSpecial Instruction, REHS3007 for concerns of fuel dilution.If fuel dilution levels are above 6 percent and viscosity is below the limits outlined in Table 1 from Special Instruction, REHS3007, the injectors should be checked against the affected serial number ranges listed in Table 2.

Note: Most Cat^® engines are shipped with 10w30 engine oil.
