Replacement of wheel cylinder (yellow)
The machine is folded out to the work-
ing position, the wheels (B) are lifted
off the ground and pressure relieved
from the wheel cylinders (A).
1. Disconnect hoses from cylinder
2. Support cylinder
3. Remove split pins from pins, remove pins
4. Remove cylinder
5. Fit new or repaired cylinder
After the wheel cylinders are fitted, they are actuated until they show a slight trav-
el. Reverse cylinder until it returns to start position. Move cylinder backwards and
forwards several times.
If cylinder is not bled correctly as described above, there is a risk that part of the
machine can suddenly move much quicker than normal, and before the tractor
driver can prevent it. This is because air (unlike oil) is compressible. A section can
therefore swing out very quickly if air bleeding is not performed correctly. This rep-
resents a major risk of injury to personnel and of damage to the machine.
Ensure no personnel are within the extension radius of the side sections.
Replacing gaskets on the wheel cylinder
See the section "Replacing gaskets on tilt cylinder"
Replacing the harrow hoist cylinder (white valve block no. 3).
The machine is extended to the work-
ing position, the wheels are raised so
that the two cross-kill rollers are rest-
ing on the ground. The harrow arms (A)
are then lowered so that the harrow
tines (B) rest on the ground. The har-
row hoist cylinders are then depres-
surised (A).
