Within the hour you could have the L130's electrical schematics open on the bench, tracing a circuit the way Link-Belt's own techs do: the Link-Belt L130 service manual PDF, factory book 1121, runs 723 pages on this wheel loader. Wiring diagrams and troubleshooting charts carry the electrical side from battery service to the instrument cluster, while a dedicated hydraulic schematic maps the loader control system, pumps, and cylinders; the service tool software section on the ESX and DBU controllers fills the final quarter of the book. Torque the axle's notched nut to 400 Nm and pull quarter-inch Grade 5 hardware to 9 to 11 pound-feet instead of going by feel. Guess wrong once and you pay for the teardown twice. Bookmarked and text-searchable, this download puts the right spec in front of you the first time.

Link-Belt L130 Common Problems This Manual Covers
Link-Belt L130 loader hydraulic power fades, lift arms slow and bucket won't curl under load
Check hydraulic oil level and warm the system before testing. Tee a gauge into the loader valve inlet and verify pressure reaches 4060 PSI at relief. If pressure stays low, trace the circuit on the hydraulic schematic on page 723, then inspect the pump suction line for air leaks at every fitting.
Manual Section: Hydraulic System Description p. 473Final drive growls and leaks oil at the axle end, hub runs hot during travel
Drain the final drive and inspect the oil for metal before roading the machine again. During reassembly, torque the notched nut to 400 Nm and secure the fillister-head screws with Loctite 243 at 25 Nm, following page 406. Pressure-test the wet brake at 100 bar; more than 5 bar drop in 10 minutes means a leaking piston seal.
Manual Section: Power Train p. 406Engine cranks slowly or won't turn over at all on cold mornings
Test and load-test the battery before condemning the starter. Clean both terminals and torque the 1/4 inch Grade 5 clamp hardware to 9 to 11 pound-feet per the chart on page 15. If cranking is still slow, check the starting circuit against the wiring diagram for voltage drop across the ground cable.
Manual Section: Starter Motor Removal and InstallationAir conditioner quits cooling mid-shift, blower runs but vents blow warm air
Check the fuse and blower operation first, then hang gauges on the system. Work the troubleshooting chart starting to separate a low charge from a failed compressor clutch. If the charge is down, recover the system, evacuate, and refill with exactly 2 lb of refrigerant per the capacity spec on page 37.
Manual Section: Air Conditioning SystemSteering wheel turns hard at idle and the machine wanders on the road
Verify hydraulic oil level, then check the steering control valve for a sticking spool before pulling cylinders. Inspect the center pivot and articulation joint pins for wear; the frame should swing a full 42 degrees each way without binding. If a steering cylinder is bypassing, rebuild it and torque the piston cap screw to 300 pound-feet per page 279.
Manual Section: Hydraulic Steering System Description p. 255Frequently Asked Questions
What are the standard torque specifications for Grade 5 bolts, nuts, and studs?
For a 1/2 inch Grade 5 bolt, the torque specification is 80–96 pound-feet (109–130 Newton Meters). For a 1 inch Grade 5 bolt, the torque is 580–696 pound-feet (787–944 Newton Meters). p. 15
What is the engine oil capacity for the L130 wheel loader?
The engine oil capacity with a filter change is 19 U.S. Quarts (18 Liters). p. 21
What is the procedure to reset the ESX controller hours?
The Reset Hour Meter ESX command should only be used when replacing an ESX Controller. It resets the hours to zero and should not be used on a loader with an existing controller as it makes it difficult to determine when an error occurred. p. 580
What is the recommended tire pressure for 20.5 x 25 PR tires?
The recommended tire pressure for 20.5 x 25 PR tires is 43.5 psi (300 kPa, 3.0 bar), 40 psi (276 kPa, 2.8 bar), or 50 psi (345 kPa, 3.4 bar) depending on the specific application and manufacturer. p. 428
What is the torque specification for the piston cap screw on the steering cylinder?
The torque specification for the piston cap screw on the steering cylinder is 300 pound-feet (410 Nm). p. 279
