A New Deflector Has Been Added to the Mixing Chamber {6635}

Usage:

RM-350B 7FS
Road Reclaimer/Soil Stabilizer:
RM-350B (PIN: 7FS1-UP)

Description of Change: A new deflector has been added to the mixing chamber. The deflector has been added in order to cover the gap between the mixing chamber and the upper edge of the rear door. Dust can penetrate this gap, restricting the operator's visibility and comfort. The rubber flashing will prevent material from escaping through the upper portion of the rear door.

Adaptable To: The new 196-3994 Deflector is effective with S/N:7FS00173
.

The new 196-3994 Deflector is adaptable to S/N:7FS1-00172
.

Rework Procedure

The following parts must be ordered in order to update existing machines with the new deflector.
