New Hose Assembly for the Pilot Lines Group Is Now Used on Certain D6R Track-Type Tractors {5057}
- Track-Type Tractors:
- D6R XL (S/N: S6T1-UP)
- D6R STD (S/N: S6X1-UP)
- D6R LGP (S/N: S6Y1-UP)
Description of Change: A new hose assembly is now used in the pilot lines group for the machines listed above.
The improved hose assembly has a shorter coupling which reduces hose bending stress.

New 425-3911 Hose As replaces the former 226-3512 Hose As in the 340-0117 Pilot Lines Gp for machines S6Y297-UP, S6X1617-UP, S6T0802-UP.
This new hose is not adaptable to machines S6Y1-296, S6X1-1616, S6T1-0801.
Use the following procedure to make 226-3512 Hose As for machines S6Y1-296, S6X1-1616, S6T1-0801.
In the event of failure, replace the 226-3512 Hose As with the new 226-3512 Hose As (1) .
The improved 226-3512 Hose As (1) has a new coupling for reducing hose bend stress.
