HYDRAULIC ADAPTER REPLACEMENT – continued
NOTE
Use the proper fluid adapter installation tool kit for the hydraulic adapter size being replaced. Refer
to table 1.
Each installation tool kit contains three tools: lockring removal tool, combination removal tool, and
O-ring installation tool. Use the applicable open-end wrench and socket for each tool kit. Refer to
table 1.
The replacement of the hydraulic adapters on the hydraulic servocylinders is an AVIM task.
The replacement of the hydraulic adapters on the other hydraulic components is an “off helicopter”
task.
