folding
NOTE! Take great care. The hydraulic ram for folding may be pressurised even if the implement
is not connected to the tractor.
Figure 4.6
NOTE!
The piston rod guide is tightened to 700 Nm and fitted with a mechanical rotation lock.
NOTE!
Clean the hydraulic ram thoroughly before starting work.
1 Mark the ram tube and piston rod guide in order to retighten to the same position when reas-
sembling, see “Figure 4.6”.
2 Undo the screw (A) M6x8 fully and make sure to save the steel ball (D) which forms the rota-
tion lock.
3 Fit the tool (C) onto the piston rod guide (B). Undo and pull out the piston rod guide.
4 Pull out the piston rod. The seal can now be replaced.
NOTE! Make sure you do not damage the seals or seal surfaces.
5 Check that there are no scratches on the jacket lining (E).
6 Fit in reverse order.
!
Make sure that you retighten the piston rod guide fully to 700 Nm to the mark you made pre-
viously. To refit the rotation lock, place the steel ball (D) back in the intended hole and put the
screw (A) back in place. Tighten.
Carefully flush the ram prior to assembly. Fit the ram to the implement (see “5.1 Hydraulic system
diagram” on page 44 ), and bleed the hydraulic system, see “4.10 Bleeding the folding hydraulic
systems” on page 39 .
