John Deere 300D, 310D, 315D Common Problems This Manual Covers
John Deere 310D hydraulic system pressure drops after 2-3 hours, backhoe slows down p. 636
Check hydraulic reservoir level; capacity is 41.5 L (44 qt) per page 27. Inspect the 10-micron return oil filter for clogging and replace if overdue. Measure system pressure at the main relief valve: spec is 2700 psi (18 620 kPa) per page 26. If pressure reads low, pull the pump for inspection per the Main Hydraulic System section at page 636.
Manual Section: Main Hydraulic SystemLoader bucket drifts down slowly with engine off, won't hold position p. 691
Inspect loader control valve spools for wear or internal bypass; disassemble and clean per the Loader section at page 673. Torque 27 mm relief valves to 65 N·m (48 lb-ft) and 22.2 mm relief valves to 45 N·m (33 lb-ft) per page 691. Check loader cylinder seals for bypass before reassembling the valve.
Manual Section: LoaderEngine overheats during extended digging cycles, coolant temp gauge pegs red p. 361
Verify coolant level; system holds 16 L (17 qt) per page 337. Inspect fan belt deflection: new belt spec is 8 mm at 111 N (5/16 in. at 25 lb force). Adjust via the alternator strap and torque the strap cap screw to 27 ± 3 N·m (20 ± 2 lb-ft) per page 361. Clean the radiator core and test thermostat.
Manual Section: Engine Auxiliary SystemsBackhoe boom and dipper sluggish under load, dig force noticeably reduced p. 808
Measure backhoe circuit relief pressures. On 300D, crowd out (B) should hold 22 000 kPa (3200 psi); on 310D/315D verify 24 100 kPa (3500 psi) per page 808. If a relief valve is venting early, clean or replace it. Inspect the backhoe control valve for worn spools; rebuild per the Backhoe section at page 744.
Manual Section: BackhoeEngine cranks slowly or won't start in cold weather below freezing p. 478
Load-test the battery. Minimum spec is 625 cold cranking amps at -18°C per page 478. Check electrolyte level and hydrometer reading on each cell; verify terminal connections are clean and tight. If the battery fails load test, replace it. Inspect cold weather starting aids per Engine Auxiliary Systems at page 354.
Manual Section: Electrical SystemsBoom cylinder leaks past seals, arm slowly loses height when idle p. 792
Remove and disassemble the cylinder per page 744. Inspect bore, rod, and seals for scoring. Torque boom piston nuts per page 739: 300D snugs at 100 N·m (74 lb-ft); 310D/315D snugs at 250 N·m (185 lb-ft), both require an additional angle turn. Torque rod guide spanner nuts to 173-237 N·m (128-175 lb-ft) per page 792.
Manual Section: BackhoeFrequently Asked Questions
What are the torque specs for hydraulic pump bolts on John Deere 310D?
For the Main Hydraulic Pump (SN -802199), pump section cap screws and threaded studs should be torqued to 88-102 N·m (65-75 lb-ft). For Main Hydraulic Pump (SN 802200- ), the pump housing nut torque is 272 N·m (200 lb-ft), and auxiliary pump-to-main pump cap screws are torqued to 193 N·m (142 lb-ft). Additionally, reverser charge pump cap screws require a torque of 23-30 N·m (17-22 lb-ft).
What are the replacement specifications for Hydraulic pump?
For the Main Hydraulic Pump (SN 802200- ), only seals are serviceable. If any other parts are found worn or damaged, the entire pump must be replaced. It is also important to lubricate all internal surfaces with clean hydraulic oil before assembly, as premature pump failure can result if the pump is assembled dry.
How do you fix john Deere 310D hydraulic system pressure drops after 2-3 hours, backhoe slows down?
Check hydraulic reservoir level; capacity is 41.5 L (44 qt) per page 27. Inspect the 10-micron return oil filter for clogging and replace if overdue. Measure system pressure at the main relief valve: spec is 2700 psi (18 620 kPa) per page 26. If pressure reads low, pull the pump for inspection per the Main Hydraulic System section at page 636.
How do you fix loader bucket drifts down slowly with engine off, won't hold position?
Inspect loader control valve spools for wear or internal bypass; disassemble and clean per the Loader section at page 673. Torque 27 mm relief valves to 65 N·m (48 lb-ft) and 22.2 mm relief valves to 45 N·m (33 lb-ft) per page 691. Check loader cylinder seals for bypass before reassembling the valve.
