Consumables, materials and expendables

Name	Identification/References	Quantity
Drycleaning solvent	C-304	AR
Clean cloth	C-516	AR

Procedure

1. Look to the sight gauge on the Hydraulic Reservoir Filter Module (HRFM) through the screen of the right transmission fairing.

2. If the sight gauge is dirty, do the steps that follow:

   1. Remove the right transmission fairing (DMC-505-A-53-40-02-00A-520A-A).

   2. Clean the sight gauge with a Clean cloth (C-516) moist with Drycleaning solvent (C-304).

   3. Install the right transmission fairing.

3. Visually examine the sight gauge for cracks or discoloration.

4. If there are cracks or discoloration on the sight gauge, replace the HRFM.

5. Make sure the level of hydraulic fluid on the sight gauge is between the FULL line and the REFILL line.
