need to mark hoses or trace routes. See “Hydraulic
Connectors and Torque” on page 70.

806-105C U-BOLT 5/8-11 X 4 1/32 X 6
326. Relocate the valve group:
160-331S NTA607HD HYDRAULIC VALVE ASY
further outboard on the wing. The new U-bolt
center-line is approximately 3.8 cm (1.5 in) inboard
of the inside rear face of the wing gauge wheel
plate
. Secure valve group with saved U-bolt ,
