Need factory numbers for your Hyundai HL760-3 wheel loader? This 481-page Hyundai HL760-3 service manual PDF breaks down the whole machine: engine, power train, brakes, steering, work equipment, and electrical. You get complete electrical circuit diagrams with connector layouts and component specifications, hydraulic schematics for the main control valve, priority valve, and steering circuit, plus step-by-step disassembly and assembly procedures for the transmission, axles, and cylinders. Every system carries its own operational checks, troubleshooting charts, and test-and-adjustment routines. Set the clutch cut-off pressure switch at 25 kgf/cm2, confirm stall speed lands between 2170 and 2310 rpm, and torque the engine mounting bolts to 13.3 kgf·m. A dead loader over a hydraulic puddle earns nothing. This bookmarked PDF opens on any device; grab your tablet, walk out to the machine, and start wrenching.

Hyundai HL760-3 Common Problems This Manual Covers
Hyundai HL760-3 will not move or drive power very weak in all gears
Check transmission oil level, then warm the oil by running 15 seconds in neutral (page 107). Test converter stall speed; it must fall between 2170 and 2310 rpm per page 110. A low reading with weak drive points to clutch element leakage, so measure clutch pressures before condemning the pump.
Manual Section: Transmission TroubleshootingSteering wheel heavy and slow to respond, worst at engine low idle
Verify hydraulic oil level and check the priority valve for a stuck spool first. Inspect the steering pump for wear if effort stays high at all engine speeds. After any steering cylinder reseal, torque the gland to 60 ± 6 kgf·m (434 ± 43 lbf·ft) per page 312 or it will leak again.
Manual Section: Steering System Troubleshooting p. 248Hydraulic oil overheats under load, boom and bucket slow down when hot
Check hydraulic oil viscosity and level before anything else, then clean plugged oil cooler fins with compressed air. Test main relief pressure; system relief should read 200 ± 5 kg/cm² (2845 ± 70 psi) per page 373. Holding a function over relief builds heat fast, so also check the work circuit for internal leakage.
Manual Section: Work Equipment Hydraulic Troubleshooting p. 373Brake fail warning lamp comes on during operation while pedal still feels normal
Check service brake oil pressure right away and park the machine; the lamp means pressure is below normal range. Trace the circuit on the hydraulic schematic on page 211, then inspect the accumulator and cut-off valve. Test the clutch cut-off pressure switch as well; rated setting is 25 kgf/cm² per page 118.
Manual Section: Service Brake Troubleshooting p. 211Boom drifts down with loaded bucket parked, bucket curls open on its own
Measure cylinder drift with the bucket loaded and oil at operating temperature. Boom cylinder rod retraction beyond 40 mm or bucket cylinder retraction beyond 20 mm exceeds the standard on page 376. Inspect the main control valve spools and cylinder piston seals for leakage, and replace any seals that fail the drift check.
Manual Section: Work Equipment Hydraulic Troubleshooting p. 376Frequently Asked Questions
How do I clear fault codes on a Hyundai HL760-3?
To display and clear fault codes, you must select neutral on the gear selector. The spanner icon on the display indicates an active fault, and selecting neutral allows the fault code to be displayed for investigation. p. 64
What is the torque converter stall speed for a Hyundai HL760-3?
The torque converter stall speed for the Hyundai HL760-3 should be within the range of 2170 to 2310 rpm. If the stall speed is outside this range, it may indicate a problem with engine power or the torque converter itself. p. 110
What are the replacement specifications for Transmission clutch packs?
The plate clearance for clutch K1 is 2.4 ± 0.2 mm, while for clutches K2 and K3, it is 1.8 ± 0.2 mm. For clutch K4, the plate clearance is 1.2 ± 0.2 mm. p. 154
What is the recommended oil capacity for the engine oil pan?
The engine oil pan capacity for the Hyundai HL760-3 is 22.4 liters (5.9 U.S. gallons). p. 27
What is the tightening torque for the engine mounting bolt and nut?
The tightening torque for the engine mounting bolt and nut (size M12 x 1.25) is 13.3 ± 2.7 kgf·m (96.2 ± 19.5 lbf·ft). p. 30
Is this Hyundai HL760-3 manual a download or a disc?
