 (1)  Do the steps that follow to find the thickness of the shims (29) for each of the hydraulic tubes (24, 25, 26):
 NOTE: Do not install the O-rings, backup rings, or shims at this
____
 time.

 (a)  Do the steps that follow to measure dimension A on each hydraulic tube (24, 25, 26): 1) Install the hydraulic tubes (24, 25, 26) in the RAT strut
 housing (16). 2) Tighten the tube nut (27), on each hydraulic tube (24, 25, 26), by hand until it touches the end flange (28).
 3)  Measure the clearance, on each hydraulic tube (24, 25, 26), between the surface of the RAT strut housing (16) and the inner face of the tube nut (27).
 4)  For each hydraulic tube (24, 25, 26), write this clearance as dimension A in Table I.
