New Holland LM740 Common Problems This Manual Covers
New Holland LM740 engine cranks but will not start, or starts then stalls under load
Bleed air from the fuel lines and replace the fuel filter before anything else. Work through the engine troubleshooting procedures starting on page 56. Test the injectors; opening pressure should be 245 bar per page 38. If you pull the injection pump, torque its mounting bolts to 12 plus or minus 5 Nm, listed on page 69.
Manual Section: Engine Troubleshooting p. 56Transmission slipping with low clutch pressure, machine loses drive when boom is loaded
Check transmission oil level cold and hot before condemning hard parts. Test clutch pressure; a stuck regulating valve or worn piston sealing rings will bleed it down. During reassembly, torque the regulator sleeve to 61-68 Nm and verify clutch piston to separator disc clearance of 1.22-2.74 mm, both covered on page 113.
Manual Section: Powershift Transmission p. 70Hydraulic system slow and weak, boom will not lift rated load to full height
Verify hydraulic fluid level first; the system holds 170 litres, listed on page 32. Test main relief pressure with a gauge at the pump; spec is 245 bar on page 30. If pressure stays low, replace the filters and inspect the pump and control valve using the hydraulic system section starting on page 276.
Manual Section: Hydraulic System p. 276Loud grinding or whining noise from hydraulic pump, worse at high idle
Inspect the suction hose for collapse and check every suction-side clamp for air leaks; cavitation sounds like gravel in the pump. Check fluid level, then tighten or replace loose fittings and bleed the system. Confirm the pump still builds 245 bar at relief, spec on page 30, before blaming the drive coupling or shaft.
Manual Section: Hydraulic System p. 276Transmission runs hot with harsh gear engagement and torque converter noise under load
Clean the cooler and radiator fins and confirm oil level before tearing anything down. Inspect the modulating valve for varnish and sticking; harsh engagement usually starts there. On reassembly, torque the modulating valve and inching valve to 81-88 Nm per page 113, and trace oil flow on the hydraulic schematic.
Manual Section: Powershift Transmission p. 70Frequently Asked Questions
What are the torque specifications for the engine mounting bolts on the New Holland LM740?
The engine is secured to the machine frame by three mountings. When refitting the engine-transmission assembly, the nuts and bolts securing the engine to the mountings must be tightened to a torque of 120 Nm. p. 54
How do I bleed the hydraulic system after maintenance on a New Holland LM740?
To bleed air from the cooling system, start the engine and run at idle for at least five minutes. After this time, top up the coolant level as necessary. Then, increase engine revolutions to warm the coolant until the thermostat opens, and keep revolutions high to release all remaining air from the circuit, which takes about 15 minutes from the time the thermostat opens. p. 55
What is the procedure for bleeding the brake system on the New Holland LM740?
Brake bleeding requires two operators: one in the cabin to press the brake pedal and top up the reservoir, and one outside to open and close the bleed screws. Start with the rear axle, then proceed in the order: rear right-hand axle, rear left-hand axle, front left-hand axle, and finally the front right-hand axle. p. 122
What is the correct oil pressure for the engine when running hot?
When the engine is running hot, the oil pressure should be 0.70 bar at idle and 3.50 bar at maximum rpm. p. 37
What is the required clearance for the clutch A discs?
The required clearance for the clutch A discs is 1.22 to 2.74 mm. If the clearance is greater than 2.74 mm, you must add one steel outer disc under the end plate. p. 133
What do I get after purchasing this New Holland LM740 manual?
