No.: 18 TS-4Rev November 29, 2018 TO: Service Locations FROM: Service Systems Development SUBJECT: DD Heavy Duty Platform Accessory Drive Belt Note: This document supersedes 11 TS-11, 12 TS-10, 13 TS-29, 14 TS-28, and 17 TS-9. ISSUE The belt drive system is creating noises and/or throwing belts. It’s possible to misdiagnose a belt tensioner as the primary failed part. Material testing and inspections in Detroit shows a high No Trouble Found rate on belt tensioners. This is due to some repair shops not following the symptom-based troubleshooting “Belt Coming Off” or “Belt Drive Noise” found in the troubleshooting manuals. CAUSE Winter is prime-time for old, worn out, and aged belts to begin squeaking (noise) due to material hardening and excess moisture. Belts are a maintenance item and are not covered under any warranty. The belt drive system on the front of the engine is a complex system consisting of numerous components that must work in harmony with each other in order to function correctly. Normal variation in the alignment of these parts and worn out belts can lead to noisy belts and throwing of belts. REQUIRED ACTION In September, 2016, and October, 2017, symptom-based troubleshooting “Belt Drive Noise” (found in the “Noise” chapter) and “Belt Coming Off” were updated in the EPA07/10/GHG14 DDEC VI/10 Electronics and Troubleshooting Manual (DDC-SVC-MAN-0084) and GHG17 Troubleshooting Manual (DDC-SVC-MAN-0191). This troubleshooting must be utilized. Do not replace the belt tensioner unless the troubleshooting calls for it. For these complaints, a new belt or belts will usually correct the problem. A belt coming off after installation is typically due to improper installation of the belt, or the use of an incorrect belt. Continued noise after belt replacement is typically due to improper installation of the belt, damaged belt pulleys, pulley contamination from old belt material or fluids (coolant, oil, fuel, belt dressing, etc.), or use of an incorrect belt. When replacing the belts, reference the “Poly-V-Belts” chapter in the EPA07/10/GHG14 Engine Manual (DDC-SVC-MAN-0081) and the “Belt Drive” chapter in the GHG17 DD Platform Workshop Manual (DDC-SVC-MAN-0190). These chapters were updated in February, 2018. Various belt information videos were published in February, 2018, and can Detroit Diesel 13400 Outer Drive, West / Detroit, Michigan 48239-4001 18 TS-4Rev -2- 12/4/2018 be found on DTNAConnect.com > Reference > Detroit Multimedia > DD Platform > Belt Tensioner. In October, 2016, the belt maintenance interval was reduced to 150,000 miles for long haul service and 105,000 miles for short haul and severe service. Reference the DD Platform Operators Manual (DDC-SVC-MAN-0189) found on DTNAConnect.com > Search Literature > Detroit Literature > DD13/DD15/DD16. No logon is required to access this manual. In March, 2018, new belts became effective at the truck plants to reduce belt issues by better accommodating variability in the belt drive system. These belts carryover the improvements first advertised in Technical Service letter 17 TS-9 for service-only belts for the DD13/DD15 onhighway truck engine with the variable speed water pump. These belts are now released for production with a new part number, and are joined by new belts for the fixed speed water pump for all EPA10 and later on-highway truck engines. Do not use belts from incorrect engine types. For instance, don’t use a belt from an engine with a fixed speed water pump on an engine with a variable speed water pump. The fixed speed water pump belt is 9mm longer and results in slack in the belt with the tensioner operating near the end stops and can cause the belt to come off. Refer to PartsPro on DTNAConnect.com for the latest belt part number information for a particular unit. REQUIRED MATERIAL If the belts do need replacing, Table 1 provides a list of the new belt part numbers that superseded the prior part numbers. Stock of the former part numbers CANNOT be returned.

Variable Speed Water Pump Fixed Speed Water Pump Figure 1 – Water Pump Identification CLAIM PROCESS Normal in-warranty procedures apply. Proactive removal of properly functioning parts is not allowed under warranty. Again, belts are maintenance items and are not covered under any warranty.
