Improved Hydraulic Line For Pilot Control Increases Service Life {5057}
Usage:
928G (6XR, 7SR) Wheel Loaders;
IT28G (8CR, 9AR) Integrated Toolcarriers
Description of Change: The material of the 118-1032 Hose Assembly changed to a two-wire braid reinforced high pressure hose. This material should provide a longer service life compared to the single wire braid reinforced hydraulic hose material.
Adaptable To: This was effective with 928G (6XR1669, 7SR982) Wheel Loaders and IT28G (8CR1882, 9AR499) Integrated Toolcarriers. This change is adaptable to earlier machines.
If fabricating the 118-1032 Hose Assembly, use 122-6889 Hydraulic Hose, 124-2114 Coupling, and 124-2130 Coupling.
