Excavator
320E (S/N: LAK1-UP)

Description Of Change: The upper frame assembly has been updated on the machines that are listed above. The new upper frame assembly has an extra hole to change the magnet cable routing to prevent interference with the machine harness. A new clip that secures the machines harness is also used. The new clip prevents the harness from moving freely.

Adaptable To: The part number for the improved 381-3409 Upper Frame As will remain the same. The new 4K-8864 Clip is a direct replacement for the former 8M-2773 Clip. Refer to the following illustrations for the new and former upper frame and cable routing along with the location of the new clip.
