EAGLE (SPB / SPC) BOOM
Adjustments
WARNING! Do not allow anyone under the
boom while adjustments are taking place.
IMPORTANT! To maximise boom life and per-
formance, re-tighten all boom fasteners and
inspect the boom for proper adjustment after the
first 8 hours of use.
IMPORTANT! Make it a daily (8 hours) habit to
inspect the boom for need of adjustment.
IMPORTANT! Every 40 hours, the break-away
clutch cap screws must be torqued to 55 Nm to
prevent boom damage.
Before adjustments are made check the following:
•
Sprayer is lubricated to scheduled requirements.
•
Tractor and sprayer are on level ground.
•
Boom is unfolded, except where specific guide-
lines are given.
NOTE! Adjustment of hydraulic cylinders is best done
without pressure in the hydraulic system.
Checking and adjusting sprocket timing (SPB)
1 With boom unfolded in the spraying position and
standing on the front side of the boom, check to
th
ensure that the 7
pin connection (A Fig 19) in the
timing chain, is aligned with the centre line between
the sprocket cap screws (B Fig 19).
2 To adjust timing, loosen turnbuckles on the front and
rear cables until slack.
3 Standing on the front side of the boom, position the
th
7
pin (A Fig 19) of the timing chain on the sprocket
as indicated in step 1.
4 Adjust front and rear cable tension (Refer to Adjust-
ing front fold cable (Page 14) and Adjusting rear
cable (Page 15)).

Aligning wing assemblies
1 With the boom unfolded and in the working position,
check alignment of the intermediate section with the
centre frame.
2 With the fold cylinder pressurised, determine if the
intermediate section needs to be adjusted to the
front or rear to come into alignment with the centre
frame.
NOTE! Because of adjustments made later, it is
better to start with the wing assemblies angled
slightly to the rear.
3 Relieve pressure from cylinder by folding boom in a
few inches.
NOTE! Cylinder rods have a machined flat, which
if visible, can be used for adjustments. If using the
machined flat for adjustment, leave the rod eye
pinned to the boom and loosen the lock nut. Refer
to Fig 30 on page 16.
4 Disconnect the cylinder rod eye (B Fig 20) from the
intermediate boom section.
5 Loosen the lock nut (A Fig 20) and adjust the rod
eye (B Fig 20) in to move boom forward or out to
move boom rearward. Tighten the lock nut (A Fig
20).
6 Attach the cylinder rod to the boom and pressurise
the cylinder to check boom alignment.
