Subtask 29-11-49-420-065
A. Installation of the Hydraulic Low-Pressure Switch Tube R (Ref. Fig. 407/TASK 29-11-49-991-910) R PRE SB RA32029-13
(1)
Remove the protective covers from the hydraulic low-pressure switch tube (15), the fitting on the pressure hose/tube and the hydraulic low-pressure switch.
(2)
Loosely connect the low-pressure switch tube (15) to the pressure hose/tube.
(3)
Loosely connect the low-pressure switch tube (15) to the hydraulic low-pressure switch.
(4) Install the clamp (20) on the low-pressure switch tube (15). Attach
the two tubes to the channel with the bolt (5), the washer (10) and
the clamps (20).
(5) Make sure that the low-pressure switch tube (15) is in the correct
position on the engine.
NOTE : Use a second wrench to hold the fittings when you TORQUE the____
coupling nuts. This prevents damage to the tube assemblies.
(6) TORQUE the coupling nut on the low-pressure switch (15) to between 7
and 7.68 m.daN (51.62 and 56.63 lbf.ft).
