Hydraulic Blade Reversing
The Blade can be manually rotated 180
o
for backfilling
and then angled while in reverse position with hydraulics.
1.
Lower blade until it is resting on the ground.
2. Remove hairpin cotter (#1) and clevis pin (#2).
3. Remove cap screw (#8) and pivot cap (#3),
4. Remove locknuts (#9), bolts (#7), and hydraulic
angle plate (#4).
5. Turn hydraulic angle plate (#4) upside down and
attach it or the stored drive pivot cap (#6) to blade
pivot shaft (#5) with pivot cap (#3) and cap screw
(#8). Draw hex flange cap screw up snug, do not
tighten at this time.
NOTE:
The stored drive pivot cap (#6) can be used
in lieu of hydraulic angle plate (#4) in step 5 below.
6. With tractor 3-point, raise blade up, rotate blade 180
o
,
and then lower blade until on the ground.
7.
Remove hex flange cap screw (#8), pivot cap (#3),
and hydraulic angle plate (#4) or drive pivot cap (#6).
8. Turn hydraulic angle plate (#4) upright and reattach it
to blade pivot shaft (#5) with 3/4"-10 x 5 1/2" GR5
bolts (#7) and locknuts (#9). Draw locknuts up snug,
do not tighten at this time.
9. Attach pivot cap (#3) to hydraulic angle plate (#4)
with 3/4"-10 x 1 1/2" hex flange cap screw (#8).
10. Tighten hex flange cap screw (#8) and locknuts (#9)
to the correct torque.
11. Attach hydraulic cylinder to hydraulic angle plate (#5)
with clevis pin (#2) and secure with hairpin clip (#1).

Note: The removed and stored drive pivot
cap (#6) is shown as an alternate method for
securing the moldboard to the mainframe
while manually rotating the blade 180
