3-4 HYDRAULIC LEVELER (OPTION)
3-4.1
Thread a 1-1/2-6 hex nut onto the lev-
eler screw assembly (See Figure 3-4). Ini-
tially leave approximately 6-1/2" of threads
visible between the 1-1/2-6 hex nut and the
leveler spring nut. Further adjustment may
be required.
3-4.2
Thread the leveler tube onto the leveler
screw assembly until it contacts the 1-1/2-6
hex nut. Rotate the tube so the grease zerk
hole in the threaded end points upward.
3-4.3
Slide the leveler cross over the front
end of the leveler tube.
3-4.4
Insert the 3-1/2 x 6 hydraulic leveler cyl-
inder into the front end of the leveler tube
and pin using two 5/8" steel leveler pins. Ro-
tate the cylinder so the hydraulic ports point
to the left side of the implement.
3-4.5
Slide the leveler cylinder cross up to the
cylinder and secure with 1/2-13 x 2 hex head
cap screws and hex lock nuts. Install the
screws from the back of the leveler cylinder
cross, pointing forward for proper operating
clearance. The indicator window of the lev-
eler cylinder cross should point to the right
side of the implement.
3-4.6
Insert a plastic wear flange bearing in
each leveler cross bracket. Install the plastic
wear flange bearing from the tube side of the
bracket.
3-4.7
Slide the leveler cross brackets onto the
leveler cylinder cross and secure with wash-
ers and 5/16" x 2-1/2" spring slotted pins.
3-4.8
Attach the leveler cross brackets to the
top of the leveler L link using 3/4-10 x 3-1/2
hex head cap screws and hex lock nuts.
3-4.9
Install grease zerks in the threaded end
of the leveler tube and the leveler cylinder
cross.
3-4.10
With a 1/2-13 x 2 hex head cap screw
and hex lock nut, attach the leveler indicator
gauge to the leveler cylinder cross. Do not
over tighten this screw, as the indicator
gauge must be free to pivot about this joint.
3-4.11
Rotate
the
cross-hole for the level indicator rod is hori-
zontal. Wrench-flats are provided at the
threaded end of the leveler tube to make this
adjustment. Secure the 1-1/2-6 hex lock nut
to prevent the leveler tube from rotating fur-
ther.
3-4.12
Insert the threaded end of the leveler
indicator
rod
cross-hole and the other rod end through the
bottom leveler indicator hole. Secure the in-
dicator rod with a 3/8-16 hex lock nut.
3-4.13
Install 1/32" restrictor fittings in the lev-
eler cylinder.
Note: These are smaller restrictor fittings than
those used in the fold system.
