III. ADDITIONAL SUSPENSION SPRING
FOR FC 202 R
(Kit No. 108 6660)(photo 45)
The additional compensating spring bal-
ances the extra weight of the roller
conditioning unit assuring smooth floata-
tion even when working on soft terrain.
To install the kit proceed as follows.
- Remove the existing compensating
springs.
- Attach central spring with shock ab-
sorber (C) to lower support (I) with
pin (G) and 2 cotter pins (dia 5x22).
- Hook both lateral springs (L) to lower
support (I) and attach them to the
upper support (S) with 2 hexagon bolts
(K)(M16x30) and 2 spring washers (M16).
- Bolt the lower support with installed springs to the lower hitch yoke (O) using
the hexagon bolt (U)(M16x120) and a self-locking nut (M16).
- Apply grease to one of the original two M16x210 bolts (Y) and screw this bolt onto
the central spring to attach the upper supports (S) to upright (V) of the 3-point
frame. Do not forget to put lock nut (W) over the upper support and spring washer
(dia 16 mm) under bolt head (Y).
Cutterbar down pressure is adjusted by rotating bolt (Y) after loosening lock nut
(W). It should be adjusted in such a way that the left or right side of the header
can be raised off the ground with a force of 50 daNm, which corresponds to a weight
of 50 kf/110 ft.lbs. Retighten lock nut (W) after setting down pressure.
