Interference May Occur Between the Clips of Air Cleaner Group, the Hose Assembly of Steering Lines Group, and the Hose of Air Lines Group on 777G Off-Highway Trucks{1051, 1054, 1071, 4304}

Usage:

777G RDR
Off-Highway Truck/Tractor:
777G (S/N: T5A1-UP; TNM1-UP; RDR1-UP; T4Y1-UP)

Introduction

The problem that is identified in the technical information bulletin that follows does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.

Problem




Illustration 1g03398907

Arrows indicate interference between the hose assembly and clips, and the hose and clips

The orientation and location of 5P-7469 Clip (2) and 5P-7468 Clip (3) can interfere with the 363-7571 Hose As (1) that is part of 309-1347 Steering Lines Gp or the 186-2002 Hose (4) part of 295-5152 Air Lines Gp and 295-5151 Air Lines Gp . The clips are part of 295-5155 Air Cleaner Gp which retains the 371-1173 Hose (5). The interference can cause chafing on the 363-7571 Hose As and or the 186-2002 Hose that can lead to premature component failures. In some instances the 371-1173 Hose (5) can also chafe the 186-2002 Hose (4) causing a premature component failure.

Note: 295-5152 Air Lines Gp is used on S/N:RDR and ; S/N:T5A machines and 295-5151 Air Lines Gp is used on S/N:TNM and ; S/N:T4Y machines.

Solution

Inspect the orientation and location of the 5P-7469 Clip and the 5P-7468 Clip and the routing of the 371-1173 Hose and to ensure that:

  • No interference exists between the clips and the 363-7571 Hose As (steering system load sensing line).

  • No interference exists between the clips and 371-1173 Hose and the 186-2002 Hose .

If required, adjust the clips and 371-1173 Hose to eliminate any chafing between either 363-7571 Hose As and 186-2002 Hose .
