IMPORTANT : ALWAYS REPLACE SECURING ELEMENTS (LOCK-NUTS AND BOLTS)
WHEN THEY HAVE BEEN REMOVED 5 TIMES.
CAUTION : ALWAYS REPLACE DAMAGED KNIVES, NEVER STRAIGHTEN A BENT
KNIFE.
NEVER REPLACE ONE KNIFE ONLY PER DISC, ALWAYS REPLACE BOTH OF THEM TO
AVOID CREATING AN OUT-OF-BALANCE FORCE.
3. DISCS REPLACEMENT
To replace a disc, place a block of wood (Z) between
two discs to stop them from rotating. Unscrew the 4
nipple-screws (B) with the box spanner (T) supplied
with the machine and take the 4 conical spring washers
(C) off (photo 41 and fig. 42).
Two of these diametrically opposite bolts are also used
to secure the conical covers on top of the discs.
When remounting must the discs have their largest
diameters positioned at right angles to each other. This
positioning must be scrupulously respected so as to
avoid interference between the knives.
Take extra care when fitting the conical spring washers
(C) (fig. 42), which must be positioned with the conical
centre at the top.
Tighten bolts to a torque of 12 daNm (90 ft.lbs).
THE GMD 600 GII / 700 GII / 800 GII
DISCS SUPPLIED THROUGH OUR
S P A R E P A R T S D E P A R T M E N T
COME WITH A 1 MM SPACER (PART
no. 568 071 00) (fig. 40) ATTACHED
TO THEM. WHEN INSTALLING A
NEW DISC CHECK IF THE GAP
BETWEEN THE BLADES OR THEIR
M O U N T I N G B O L T S A N D T H E
C U T T E R B A R P R O T E C T I O N
SHIELDS IS AT LEAST 1 MM. IF
THIS IS NOT THE CASE FIT THE 1
MM SPACER BETWEEN THE DISC
AND ITS MOUNTING HUB FOR
INCREA-SED CLEARANCE (fig. 40).
THIS SPACER IS NOT REQUIRED
ON DISCS FOR GMD 600 GII-HD /
700 GII-HD / 800 GII-HD.
Dull knives require more horse power to cut the crop
and will leave an uneven stubble.
Worn knives should either be turned over on the same
disc to use the other cutting edge, or replaced. When
turning or replacing the knifes, make sure there is a 1
mm minimum gap between the knives or their mount-
ing bolts and the cutterbar wear plates. If otherwise,
insert one (maximum two) distance spacer(s) (code
568 071 00) between the discs and the disc bearing
stations (only for GMD 600 GII / 700 GII / 800 GII) (fig.
40).
