Solution
Caterpillar is aware of this problem and is recommending the following interim corrective action. Please follow the Special Instruction, M0110497, "Removal and Installation Procedure for DEF Heated Lines on Certain Machine Engines" for proper Disassembly and Assembly of the DEF heated lines to avoid failures. If a failure or DEF leak is noted even after following the special instructions, please use Service Magazine, M0103829, "Diesel Exhaust Fluid (DEF) Heated Lines May Be Damage on Certain Cat® Machines" for a temporary line repair. If additional help is needed, please go to the Parts Tech tab and enter a Product Health ticket in PSCRM.The new hose assemblies are listed in Table 1.
