![John Deere 316 318 420 Repair Manual [Lawn Garden Tractor]](https://youfixthis.com/wp-content/uploads/2016/06/2016-06-16_15-27-22-300x300.jpg)
Part of the John Deere Repair Manuals.
This is the John Deere 310G Technical Manual PDF mechanics actually need: OEM #TM1886, 780 pages of factory procedures covering every system on the 310G Backhoe Loader from torque converter to backhoe swing frame. You get hydraulic schematics with full circuit routing through the main pump, loader valve stack, and backhoe cylinders, plus page after page of torque tables and exploded views spanning axles, transmission, MFWD, steering, and the operator station. Full rebuild sequences for the PowerTech 4.5L and 6.8L engines walk from removal through reinstallation, and a troubleshooting section gets you to a root cause without chasing your tail on forums. Filter mounting cap screws go back to 33 ± 4 N•m (24 ± 3 lb-ft); the hydraulic pump pulls 30 kg (65 lb) on removal. No more guessing. Bookmarked and keyword-searchable, this PDF opens on laptop, tablet, or phone; bring it right to the machine.

John Deere 310G Common Problems This Manual Covers
John Deere 310G stabilizers won't raise or lower, backhoe swing slow and hesitant p. 719
Inspect hydraulic oil level and check for aeration or contamination before opening the valve body. Remove and clean the backhoe control valve swing section spool per the disassembly procedure in Section 33. Torque the spool end screw to 9.5 N•m (84 lb-in.) after reassembly (page 719). If stabilizers still don't move, clean the suction strainer.
Manual Section: BackhoeTransmission slips out of gear or shifts hesitate and engagement feels sluggish under load p. 547
Check hydraulic and transmission oil level before anything else. Drain and replace the hydraulic oil filter, torquing filter mounting cap screws to 33 ± 4 N•m (24 ± 3 lb-ft) per page 547. If shifting stays rough, inspect the power shift clutch pack and hydraulic control valve in Section 03 for worn friction discs or sticking spools.
Manual Section: TransmissionEngine drags and cranks slowly on startup, fuel delivery blocked or engine won't fire p. 287
Remove and inspect the fuel pick-up tube strainer for debris, then test the lift pump for delivery pressure. If the engine still won't fire, drain the tank and reinstall the drain screw to 59 N•m (44 lb-ft) as shown on page 287. Verify no water contamination before refilling.
Manual Section: Engine Auxiliary SystemsECU receives no power and pump gets no signal, machine won't respond to controls p. 367
Inspect all ground connections at the ECU and pump, cleaning any corrosion. Check battery terminals and torque post nuts to 9.2 N•m (page 367). Measure resistance through the wiring harness from ECU to pump connector; high resistance indicates a damaged harness segment. Refer to Wiring Harness procedures in Section 16.
Manual Section: Electrical SystemsAir intake hose splits or clamps loosen, engine loses power and smokes under load p. 276
Pressurize the intake system to 13.8-20.7 kPa (2-3 psi) using the leakage test procedure on page 276. Listen and feel for leaks at every hose clamp, intercooler connection, and intake manifold joint. Tighten or replace any suspect clamp or hose section. Look for oil residue near joints as a secondary indicator of a persistent leak.
Manual Section: Engine Auxiliary SystemsFrequently Asked Questions
What are the torque specifications for the John Deere 310G hydraulic pump?
The pump section cap screws for the hydraulic pump should be tightened to a torque of 339 N•m (250 lb-ft). This specification is found in the 'Assemble Hydraulic Pump' section of the manual.
How do I release the transmission lock on a John Deere 310G?
To release the transmission lock, which is the park brake, you need to cycle the park brake switch. After starting the machine, turn the park brake switch ON/OFF to disengage the lock.
How do you fix john Deere 310G stabilizers won't raise or lower, backhoe swing slow and hesitant?
Inspect hydraulic oil level and check for aeration or contamination before opening the valve body. Remove and clean the backhoe control valve swing section spool per the disassembly procedure in Section 33. Torque the spool end screw to 9.5 N•m (84 lb-in.) after reassembly (page 719).
