Improvements to Implement Steering Pump Suction Tubes {5057}

Usage:

938H JKM
Integrated Toolcarrier:
IT38H (S/N: JNJ1-UP)
Wheel Loader:
938H (S/N: MJC1-UP; JKM1-UP; LKM1-UP)

Description of Change: The manufacture of the steering pump suction tubes and hump hoses have improved the brazing process on the tubes. The new process will improve service life and reliability.

Adaptable To: The changes to the process on the 262-5578 Tube Assembly and the 262-5579 Tube Assembly are adaptable to the following machines:

Table 1
Model     Serial Number    
938H     (S/N: JKM1-730)
