6 Valve block
102-1 Filter (option)
When factory-mounted, filter (102-2) is not provided
- in this case, a hydraulic loop line is installed here.
In case of retrofits, filter (102-2) remains in place.
102-2 Filter (series equipment)
232 Lubricating oil pump
is actuated when building up pressure for opening the tailgate.
318-1 Left side tailgate hydraulic cylinder
318-2 Right side tailgate hydraulic cylinder
331 Pick-up raise/lower hydraulic cylinders
2 pieces, spring-loaded
336 Knife support On/Off hydraulic cylinder
338 Rotor cut-out clutch
345 Top tensioning arm hydraulic cylinder
346-1 Bottom left tensioning arm hydraulic cylinder
346-2 Bottom right tensioning arm hydraulic cylinder
370 Drive clutch for roller no. 3. When subject to pressure, the clutch opens so that roller no. 3 does
not drive the belts (when opening the tailgate).
513 Hydraulic accumulator
pressurised to 2 bar
626-C Shut-off tap
for left-side tailgate cylinder. Is combined with 626-D and 626-E.
626-D Shut-off tap
for right-side tailgate cylinder. Is combined with 626-C and 626-E.
626-E Shut-off tap
for belt tensioner cylinder. Is combined with 626-B and 626-C.
- blocked when 626-C and 626-D are open.
- open when 626-C and 626-D are blocked.
627 Shut-off tap
In the initial position (see circuit diagram):
- the oil supply to valve block (6), (input P) is ensured.
- the oil supply to the rotor cut-out clutch (338) is shut off.
When actuated:
- the oil supply to the valve block (6), (input P), is shut off
- the oil supply to the rotor cut-out clutch is provided.
