Spraying season doesn't wait, and the 582 pages behind OEM ID SQ-044V1 exist so a Flexi-Coil 67 or 67XL sprayer never sits parked while the weather holds. This Flexi-Coil 67 service manual PDF takes both variants from boom fold, levelling, and stabilising procedures through overhaul of the PTO-in pressure pump. Wiring diagrams trace the lighting circuits, hydraulic schematics map boom tilt and unfold, and troubleshooting tables run the plumbing, pressure, and foam marker systems from symptom to cause. Purge the plumbing lines at 827 kPa (120 psi), then torque the rear frame tension link nut to 108 Nm (80 lb ft). Guess either number and you buy the repair twice. The text layer searches clean, bookmarks split out every system, and any page you print can sit on the bench and take grease while your spraying window stays open.

Flexi-coil 67, 67XL Common Problems This Manual Covers
Flexi-Coil 67XL boom pressure drops and surges when individual spray sections are shut off
Check your regulator setting before blaming the control valve. Set spray pressure 70 - 100 kPa (10 - 15 psi) above desired operating pressure, following the procedure on page 497, so the regulator has headroom when sections close. If pressure still surges, turn the tractor remote hydraulic flow down until pump speed steadies, then reset pressure.
Manual Section: Spraying Pressure System - 20.C p. 497Hydraulic oil runs hot during spray operation, pump housing too hot to touch
Measure oil temperature at the reservoir; the hydraulic drive pump is rated for a maximum of 60 \u00b0C (160 \u00b0F), listed with the pump specifications on page 487. If you are over that, close the bypass down and reduce tractor remote flow so excess oil is not being dumped and heated. Recheck temperature once the system stabilizes.
Manual Section: Spraying Pressure System - 20.C p. 487Boom frame cracking at stress points, repeat weld repairs on wing sections every season
Inspect the boom wings and center frame for hairline cracks at every weld before the season starts; a loose, flexing frame feeds fatigue straight into the boom. Lubricate the tension link threads, then torque the tension link nut to 108 Nm (80 lb ft) as specified on page 124. Reweld and reinforce cracks before spraying, not after harvest.
Manual Section: Frame Primary Frame Troubleshooting p. 124Boom wings and wheels will not lock cleanly into transport position when folding
Adjust the rear rest tube until you see a 6 - 13 mm (1/4 - 3/4 in) gap between the wing latch and the front transport rest plate, shown on page 123. Work in small steps: 3 mm of rear movement gives about 6.5 mm at the front latch. Torque the rest tube bolts to 380 Nm (85 lb ft) when finished.
Manual Section: Frame Primary Frame Troubleshooting p. 123Boom section valves respond slowly or stick, solenoids click but sections stay shut
Test voltage right at the valve connector; these electric ball valves need a full 12 volts dc at 1 amp to cycle properly. If the tractor accessory plug drops voltage, run a fused lead straight off the battery. When reinstalling a valve, torque the hex head cap screws to 1.7 Nm (15 lb in), covered on page 443.
Manual Section: Spraying Plumbing System Troubleshooting p. 443Frequently Asked Questions
What are the torque specifications for Flexi-Coil 67/67XL fasteners?
The torque specifications for fasteners depend on the grade and size of the bolt. For example, a 1/4 inch Grade 5 bolt has a dry torque of 13.6 Nm (10 lbf/ft) and a lubricated torque of 9.8 Nm (7.2 lbf/ft). Refer to the Bolt Torque Information table on page 25 for a complete list of specifications. p. 25
How do I calibrate a Flexi-Coil 67 sprayer?
To calibrate the sprayer, first determine the actual tractor ground speed by timing travel over a 30.5 m (100 ft) distance. Then, measure the volume sprayed over a known distance (400-800 m) and calculate the application rate by dividing the total volume by the area sprayed. Detailed calibration procedures are found on page 405. p. 405
What is the procedure for greasing the PTO shaft on a Flexi-Coil 67/67XL?
Grease the cross journals (4, 5, 6) every 8 hours. Grease the inner tubes (5, 7) every 16 hours. Finally, grease the shield retaining bearings (2, 3) and the push pin (1) every 40 hours. p. 74
How is the caster wheel shock/spring adjusted on a Flexi-Coil 67/67XL?
The caster wheel shock/spring should be adjusted so the distance from the bottom of the wing boom to the ground is between 81 - 84 cm (32 - 33 in). Ensure the lower spring retainer is set to the highest point for maximum spring compression. p. 256
How do I adjust the break-away tension on a Flexi-Coil 67/67XL suspended boom sprayer?
Adjust the spring inside hook length to 36.8 cm (14 1/2 in). Additionally, adjust the lower latch bolt to leave a slight gap of 1.6 mm (1/16 in) between the bolt head and the latch. Do not adjust the lower spring beyond 23.4 cm (9 1/4 in). p. 147
