Connection of hydraulic unions
The union locking procedure is as follows:
:
A
On THE BENCH
A1
Fit the nut manually on the ogive using the manual pre-assembly tool provided.
A2
Turn the wrench through 1.5 turns to compress the ogive and fasten it to the hydraulic tube.
A3
Remove the nut.
Check that the ogive can turn but does not slide.
B
ON SITE OF INSTALLATION
B1
Manually fit the nut.
B2
Close with wrench as follows:
-
0.5 TURNS for DIAMETER < 16 MM
-
0.75 TURNS for DIAMETER >= 16 MM
C
After these operations the union is closed correctly.
Tightening the nut more than indicated causes excessive deformation of the ogive and can compromise the hold of the hydraulic union.
N.B :
The hydraulic pipe must have the following characteristics:
-
It must be cut perpendicular to the axis
-
It must be burr-free.
