Procedure
Position the front and rear supports
Mount the ball bearing joint and the gudgeon
1 Attach the front (1) and rear (2) supports, keeping strictly
to the dimensions shown in the previous section.

The installer should choose the support attachment
system (welding, screwing, molding, etc) in accordance
with the composition of the material to which the
supports are attached (metal, concrete, etc).

Attach the supports on sufficiently robust
structural elements.
O
IT IS VERY IMPORTANT TO RESPECT THE DIMENSIONS: If
the dimensions are not respected, the piston rod will not
make the whole travel, meaning the mechanical slow
down system will not work.
2 Weld the support brackets (3) and (4) to the
supports (1) and (2).
O
Carry out the welding with the operator withdrawn and
at a distance. If not, the piston rod may become
damaged from Welding splatter, which could lead to
failures and oil leaks.
1 Introduce the nut (1) in the ball bearing joint (2).
2 Thread the ball bearing joint-nut set on the piston
rod (3).

Before doing this, apply grease to the ball
bearing joint and the piston rod.
3 Position the gudgeon (4) in its housing in the rear
end cap (5).
4 Introduce the horizontal pin (6), crossing the
gudgeon and the top.

ø
Horizontal pin: = 10mm, L = 57.2mm
5 Secure the pin using the safety washers (7).
6 Position the caps (8) to close the housing.
