Part of the Hyundai Repair Manuals.
All 481 pages of this Hyundai HL760 service manual PDF cover one machine: getting your HL760 wheel loader through teardown, testing, and reassembly with real factory numbers. Inside: complete electrical wiring circuits with connector pinout tables, hydraulic schematics for the brake, steering, and work equipment systems, and troubleshooting trees that trace every warning lamp back to its check point. You also get full disassembly and assembly procedures for the main pump, brake pump, steering valve, and boom and bucket cylinders. Verify stall speed at 2170 to 2310 rpm, then torque the engine mounting bolts to 13.3 ± 2.7 kg·m before you button anything up. Your loader is not earning anything parked. This PDF opens on any device with a real text layer; type the spec you need, jump straight to the right circuit, and get back to work.

Hyundai HL760 Common Problems This Manual Covers
Hyundai HL760 loader hydraulics slow and weak, boom struggles to raise or bucket won't curl
Check the hydraulic oil level and top off before chasing anything else. Inspect the suction strainer and suction lines for clogging or loose clamps pulling in air. Test main relief pressure against the 200 kg/cm2 spec on page 369; if the pump can't hit that number with warm oil, suspect internal pump wear.
Manual Section: Hydraulic System Troubleshooting p. 369Hydraulic oil foaming in the tank, pump whines and functions get jerky after warmup
Tighten every suction-side fitting and hose clamp before condemning the pump; upstream air leaks cause most foaming. Verify oil level and condition, milky oil means water contamination. Replace the suction-side O-rings, then retorque the main pump housing bolts to the chart value kg·m using the torque chart on page 18.
Manual Section: Hydraulic System Troubleshooting p. 369Transmission pressure low, machine loses drive in one gear or slips under load uphill
Verify transmission oil level first; the system holds 28 L and low oil starves the clutch packs. Run a stall test and compare against the 2170 to 2310 rpm spec on page 76. Follow the pressure checks starting, then inspect clutch pistons and seals; plate clearance should measure 2.1 mm.
Manual Section: Transmission Troubleshooting p. 76Steering feels weak and erratic, system won't build pressure at full lock
Check steering pressure at the priority valve before pulling the steering unit. Inspect the priority valve and steering valve using the steering section starting on page 246, and look for leakage past the cushion valve. If you remove the priority valve during testing, retorque its mounting bolts to 2.5 kg·m on reassembly.
Manual Section: Steering System Troubleshooting p. 246Growling noise from front axle under load, gets louder in tight turns
Drain the axle oil and check for metal flake before tearing anything down. Measure bevel gear backlash against the standard on page 170. Reset backlash if it's out of range, then torque the differential cap screws and ring gear screws to the values in the axle tightening-torque chart.
Manual Section: Power Train System p. 170Frequently Asked Questions
How do I reset the transmission fault code on a Hyundai HL760?
To eliminate a lock caused by system faults, shift the range shift lever through the NEUTRAL position. This procedure also applies to the up-shift interlock after an inductive sensor failure. p. 63
What are the replacement specifications for the hydraulic pump?
The main hydraulic pump is a fixed displacement gear type pump with a maximum delivery pressure of 150 kg/cm² (2130 psi). When reassembling, the bolts should be tightened to a torque of 5.0 ± 0.3 kgf·m (36.2 ± 2.2 lbf·ft). p. 203
What is the correct tightening torque for the engine mounting bolts?
The engine mounting bolts and nuts (size M12 x 1.25) should be tightened to a torque of 13.3 ± 2.7 kg·m (96.2 ± 19.5 lb·ft). p. 18
What is the procedure for bleeding the hydraulic brake system?
Two people are required to bleed the brake system. Put a clear plastic tube on the bleed screw (B) to route fluid to a container (A), push and hold the brake pedal, and open the bleed screw on the differential and axle assembly until hydraulic oil flows free of air. Repeat this for each bleed screw. p. 234
What is the recommended oil for the hydraulic tank and what is its capacity?
The hydraulic tank capacity is 199 liters (52.6 U.S. gal) for the tank and 294 liters (77.7 U.S. gal) for the total system. Recommended lubricants include ISO VG 32, ISO VG 46, or ISO VG 68 depending on the ambient temperature. p. 21
