Built around a single machine, this Daedong FX751 Workshop Manual (OEM #DT56-W00) runs 547 pages on the 2006–2009 FX751 tractor and covers every system from the turbocharged engine and wet-clutch transmission through the hydraulic and electrical layout. Hydraulic schematics trace each fluid path across the steering, lift, and joystick circuits, while separate diagrams map the bonnet, panel, fender, and cabin wiring. Forty-five pages on hydraulics alone bring exploded views of the line layout, proportional valve specs, and oil cooler service. Two numbers worth knowing before you start: rear wheel M18 mounting nuts torque to 274.5–318.7 Nm, and cylinder head bolts go in two stages, 49–59 Nm then 103–113 Nm. When the FX751 is down and the clock is running, open the bookmarked PDF on any device, search the spec, and finish the repair.

Kioti FX751 Common Problems This Manual Covers
Daedong FX751 power shuttle gearbox slips, jerks, or refuses to engage forward or reverse p. 189
Check transmission fluid level first; capacity is 68 L (18.0 U.S.gal.) and low fluid is the fastest diagnosis. Remove the shuttle valve assembly and measure clutch disc thickness against the specs on page 189: discs must read 2.9~3.1 mm and plates 2.24~2.36 mm. Worn past limit, replace the clutch pack.
Manual Section: 04- TransmissionLift arm raises slowly, stalls under load, or loader functions feel weak and intermittent p. 385
Replace the hydraulic filter per the schedule on page 25, every 200 hours; a clogged element cuts flow well below the main pump's rated 38.0 LPM at 2,200 rpm. Verify fluid level, then check for air ingress at suction fittings. Inspect gear pump shaft-to-bushing clearance: reject any pump where clearance exceeds 0.15 mm.
Manual Section: 10- Hydraulic SystemEngine won't start or turns over slowly in cold weather, loses power under load
Service the air cleaner first: clean the element every 100 hours and replace it annually (page 25). Bleed air from the fuel system and confirm injection pressure at 21.57~22.55 MPa, then walk the engine diagnostic and verify intake and exhaust valve gaps measure 0.15~0.25 mm (page 68).
Manual Section: 02- EngineTemperature gauge climbs into the red or coolant overflow appears at the reservoir cap
Verify coolant level first; system capacity is 10 L (2.6 U.S.gal.) and a low reading usually points to a leak. Inspect fan belt tension every 100 hours per page 25: deflection must be 7~9 mm under moderate thumb pressure (page 37). Look over radiator hoses and clamps for cracks, then run the overheating diagnostic.
Manual Section: 02- EngineCab air conditioner blows warm air or heater fails to keep the cab warm p. 509
Inspect A/C belt tension first: mid-span deflection must be 10~12 mm (page 40). Confirm the compressor clutch engages when the switch is on and verify refrigerant charge is adequate. For heat-only faults, check coolant flow to the heater core. Isolate the fault type using the visual and auditory checks in section 12-Cabin (page 509).
Manual Section: 12- CabinFrequently Asked Questions
What are the torque specs for Daedong FX751 engine or wheel bolts?
For wheel bolts, the torque for (1) Bolt & Nut is 166.7 ~ 186.3 Nm (17 ~ 19 kgf-m, 123.0 ~ 137.4 lb-ft) and for (2) Nut is 274.6 ~ 318.7 Nm (28 ~ 32.5 kgf-m, 202.5 ~ 235.1 lb-ft). For engine bolts, the Cylinder head bolt requires 103.1 ~ 112.9 Nm (10.5 ~ 11.5 kgf-m, 76.04 ~ 83.27 lb-ft) and the Connecting rod bolt requires 53.9 ~ 58.8 Nm (5.5 ~ 6.0 kgf-m, 39.75 ~ 43.36 lb-ft).
What does the FX751 warning light or fault code mean?
Take the engine oil pressure warning lamp: it comes on when oil pressure drops too low. If it lights while driving, stop the engine immediately and check the engine oil level.
How to troubleshoot Daedong FX751 no-start or hydraulic problems?
To troubleshoot engine no-start, check the battery voltage (11.8 ~ 13.2 V), the battery terminal of the start motor, the slow-blow fuse (rated capacity: 60 A), and the key switch for proper connection. For hydraulic problems, symptoms like the lift arm not lifting or lowering, or abnormal noise, require checking for insufficient oil, air in the system, clogged oil filters, or defective hydraulic pump components.
What are the replacement specifications for fuel filters?
Replace the fuel filter element every 400 hours. When fitting the new one, insert a packing between the seal and its contact surface and give it a 1/2 turn to seat it. Keep dirt and particles out of the filter during replacement.
How quickly can I access this Daedong FX751 manual after buying?
This is a 547-page searchable PDF ready for immediate download. Works on any device: pull it up on your phone while you're under the hood. No shipping, no waiting.
Am I able to print pages from this Daedong FX751 manual?
Yes, print as many copies as you want; there are no restrictions. Many mechanics print the section they need and bring it to the shop floor.
Does this Daedong FX751 Workshop Manual have electrical diagrams?
Yes. Full electrical schematics are included with wire colors, connector locations, and circuit descriptions.
