This 224-page Mustang 519 Service Manual (OEM #913302) covers everything from engine removal to telescoping boom rebuilds. The PDF provides detailed wiring schematics for the starter circuit, park brake, and steering mode troubleshooting. You also receive hydraulic schematics detailing the circuit routing for boom lift, extension, tilt cylinders, and steering. Step-by-step procedures span every major system, including the hydrostatic pump, steering control valve, axle removal, cylinder disassembly, and chassis covers. Lock down exact specifications, like torquing the wheel nuts to 450 ft.-lb. (607 Nm) and setting the steering column shaft center nut to 35 lb.-ft. (47 N·m). Your machine is down. Bookmarked and keyword-searchable, this PDF opens on any device so you can pull up the right spec and get back to work.

Mustang 519 Common Problems This Manual Covers
Mustang 519 engine cranks but won't start, or starter motor doesn't engage p. 50
Check the battery voltage first; a fully charged unit reads 12 to 13 volts (page 58). Work through the starter circuit troubleshooting sequence on page 50: inspect fuses, verify ignition relay and key switch continuity, then test the starter solenoid. Clean corroded terminals and retest before condemning the starter or replacing the solenoid.
Manual Section: Starter Circuit TroubleshootingHydraulic boom won't lift, extend, or all boom functions are weak and slow p. 127
Verify the hydraulic reservoir is full to capacity (18.0 gal / 68 L) and fluid is clean. Run the pump pressure test on page 134: target output is 3350 psi (230 bar). If pressure is low, inspect the 16-micron return filter (bypass at 50 PSI) and work through the boom lift troubleshooting chart on page 127.
Manual Section: Boom Lift Cylinder TroubleshootingSteering is stiff, pulls to one side, or mode selector doesn't switch p. 131
Test steering circuit pressure; spec is 2400 psi (165 bar) on page 131. If mode changes are the problem, check the selector switch for continuity, then test each solenoid coil for opens. A mode that won't shift almost always traces to a blown fuse or failed coil before the steer control valve itself. Inspect fuses in the electrical panel first.
Manual Section: Steering Circuit Pressure TestPark brake won't release or stays engaged, machine refuses to move p. 126
Measure park brake pilot pressure: the release threshold is 370 psi (25 bar) per page 126. If pressure is present but the brake won't release, inspect the park brake solenoid and its fuse. Verify the park brake switch is fully engaged and the relay has power. Low pilot pressure points to the hydrostatic pump as the upstream source.
Manual Section: Park Brake Circuit TroubleshootingFork self-leveling drifts out of position or stops responding during boom travel p. 130
Inspect the isolation valve and check valve in the slave cylinder circuit; the self-level check valve should hold at 65 psi (4.5 bar) per page 130. If the fork drifts, test slave cylinder port pressure: spec is 3500 psi (240 bar). A leaking counterbalance valve or contaminated check valve are the most common failure points in this circuit.
Manual Section: Boom Slave Cylinder/Fork Self Level TroubleshootingEngine temperature climbs into the red or machine loses power under load p. 20
Check coolant level first; capacity is 12 qts. (11.3 L), using a 45/55 ethylene glycol and water mixture (page 20). Remove the radiator cover (Chassis section, page 217) and inspect the core for debris. Low hydraulic fluid (18.0 gal / 68 L) compounds heat at high cycle rates. If both check out, suspect the thermostat or water pump.
Manual Section: EngineFrequently Asked Questions
What are the torque specifications for a Mustang 519?
The manual provides various torque specifications. For SAE fasteners, a 1/4 inch Grade 2 bolt requires 5-6 lb-ft (7-8 Nm), while a 1 inch Grade 8 bolt requires 900-1080 lb-ft (1220-1464 Nm). For metric fasteners, an M4 ISO Grade 8.8 bolt requires 3-4 lb-ft (2-3 Nm), and an M36 ISO Grade 12.9 bolt requires 3500-4200 lb-ft (2580-3090 Nm). Additionally, specific components like Engine Mount Bolts require 150-180 lb-ft (203-244 Nm) and Hydrostatic Pump Mounting Bolts require 220-240 lb-ft (298-325 Nm).
What are the replacement specifications for the Battery?
The replacement specification for the battery in a Mustang 519 Telehandler is one 950 minimum CCA (Cold Cranking Amps) Low-Maintenance Type, operating on a 12-Volt, Negative Ground electrical system.
