ASSEMBLY cont.
8. ATTACHING HYDRAULIC LIFT CYLINDER
IMPORTANT: SEAL ALL HYDRAULIC FITTINGS WITH A SEALANT LIQUID.
a) See ILL. 18. Attach barrel end of 4" x 24" (101.6mm x 609.6mm) hydraulic, arrow 1, to cylinder lug, arrow 2. Position cylinder
so ports are facing L.H.S. of disc. Secure with (1) 1-1/4" x 4-3/16" (31.7mm x 106.4mm) pin. Secure pin with one (1) 5/16" x 2"
(7.9mm x 50.8mm) cotter pins. To complete the assembly of cylinder, place a wooden block across top of frame for cylinder to
rest on.
b) See ILL. 18. Install 1/2" (12.7mm) x 90 degree street elbows, arrows 3 and 4, in ports on L.H.S. of cylinder. Face elbows
towards front of disc.
c) See ILL. 18. Install one (1) 1/2" x 216" (12.7mm x 5486mm) hydraulic hose, arrow 5, to rear 1/2" (12.7mm) street elbow, arrow
3.
d) See ILL. 18. Install one (1) 1/2" x 190" (12.7mm x 4826mm) hydraulic hose, arrow 6, to rear 1/2" (12.7mm) street elbow, arrow
4.
e) Run hose along frame and hitch through hose support, arrow 8, shown in ILL. 15.
f) See ILL. 18. Install proper male tips to ends of hoses, arrow 5 and 6.
g) Connect hose to tractor hydraulic couplers.
h) Block cylinder high enough for cylinder shaft to pass over top of rockshaft cylinder arm. Pump hydraulic oil into shaft side of
cylinder. When shaft side is full of oil, extend and contract cylinder approximately 10" or 12" to work air out of cylinder.
CAUTION: BEFORE APPLYING PRESSURE TO HYDRAULIC SYSTEM, BE SURE ALL CONNECTIONS ARE TIGHT AND
COMPONENTS ARE NOT DAMAGED.
i) See ILL. 18. After lift cylinder is completely filled with oil, pin shaft end of cylinder to rockshaft cylinder arm, arrow 7, with one (1)
1-1/4" x 4-3/16" (31.7mm x 106.4mm) pin. Secure pin with one (1) 5/16" x 2" (7.9mm x 50.8mm) cotter pins.
IMPORTANT:
When extending cylinder, be sure end or clevis
DOES NOT
strike rockshaft cylinder arm. Serious cylinder damage could
result.
9. See ILL. 18. Fully extend lift cylinder, arrow 1, to raise disc frame. Next install all depth control segments, (17-3/4” Lg) arrow 8, on lift
cylinder shaft, to lock frame in raised position.
CAUTION:
DO NOT LOOSEN OR DISASSEMBLE HYDRAULIC COMPONENTS WHEN THERE IS PRESSURE WITHIN THOSE
COMPONENTS. HYDRAULIC COMPONENTS UNDER PRESSURE MAY CAUSE PARTS AND HYDRAULIC FLUID TO
ESCAPE AT A HIGH VELOCITY, WHICH COULD CAUSE SERIOUS INJURY. ALWAYS RELIEVE THE PRESSURE IN THE
HYDRAULIC SYSTEM BEFORE MAKING ADJUSTMENTS TO THE HYDRAULIC SYSTEM. IF INJURED BY ESCAPING
HYDRAULIC FLUID, SEE A MEDICAL DOCTOR IMMEDIATELY.
