Which intervals, pressures and fluid figures Gehl set for its V400 skid-steer loader are settled in one source: this 120-page Gehl V400 operator manual PDF, Form No. 50950004, written for the standard and (EU) builds. Service work takes up the largest share of the book, from the engine air cleaner to routine engine care, while the controls chapter explains the operator restraint bar and safety interlock system before you ever raise the lift arms. Troubleshooting tables sort electrical, engine and hydrostatic drive faults by symptom, and a maintenance interval chart with its own log ties every service to the hour meter. Expect 3450 psi (238 bar) on both the main and high-flow circuits, and drain the hydraulic oil after 1000 hours or one year of use. Guess the oil wrong and your pump pays for it. The file is bookmarked and text-searchable, and it prints cleanly, so the service pages can live on the bench and collect grease.

Gehl V400, V400 (EU) Common Problems This Manual Covers
Gehl V400 skid-steer key turned, starter will not engage and instrument panel lamps stay dark
Before servicing the electrical system, turn the electrical engine disconnect switch OFF or disconnect the negative battery cable, as page 94 warns. Then check the electrical system troubleshooting chart on page 95. Start with the entries for entire electrical system failure and no instrument panel lamps, because a dark panel means the fault is upstream of the starter. If the lamps light but the starter still will not engage, work the starter entries next and follow the jump-starting procedure in the Operation section.
Manual Section: Electrical System Troubleshooting p. 95Lift, tilt and drive solenoids not working; loader will not lift, tilt or drive
Check the lift, tilt and drive solenoid entries in the Electrical System troubleshooting chart on page 96; check wiring yourself, but a faulty solenoid valve coil is a job for your Gehl dealer. Before chasing wiring, turn the electrical engine disconnect switch OFF or disconnect the negative battery cable, as page 94 warns, and read how the operator restraint bar and safety interlock system work in the Controls and Safety Equipment section so you know what the machine expects before it allows movement.
Manual Section: Electrical System Troubleshooting p. 95Engine cranks with good starter speed and turns over but will not start
Check the engine troubleshooting chart under the heading for an engine that turns over but will not start, and work its causes in order. If the engine has logged an active fault, record the SPN and FMI and match them against the SAE diagnostic trouble code and Cummins fault code list on page 79 before replacing any parts.
Manual Section: Engine TroubleshootingCummins engine diagnostic trouble code logged with SPN and FMI numbers the operator cannot identify
Record the SPN and FMI exactly as shown, then find the SPN in the SAE diagnostic trouble code and Cummins fault code list starting on page 79. Use the J1939 FMI descriptions in the engine diagnostic chart to read the failure mode. Correct the listed cause before you put the loader back to work moving material.
Manual Section: SAE Diagnostic Trouble Codes and Cummins Fault Codes p. 79Hydrostatic drive system overheating with sluggish acceleration and loader slow to pull away
Check the hydrostatic drive troubleshooting chart for sluggish acceleration and overheating, and work each listed cause in order. Check the hydraulic oil at the intervals in the maintenance interval chart on page 103. Replace the hydraulic oil if it is contaminated, after major repairs, or after 1000 hours or one year of use, following page 88.
Manual Section: Hydrostatic Drive System TroubleshootingBucket drifts down while lift and tilt cylinders respond slow and jerky
Check the hydraulic system troubleshooting charts for bucket drift, slow cylinder action and jerky action, and work each listed cause before you loosen any lines. Never use your hands to search for leaks; use paper or cardboard, because escaping fluid under pressure can penetrate the skin (page 11). Causes the chart routes to your dealer stay with the dealer. Inspect the condition of the hydraulic oil. Replace it if it is contaminated or past 1000 hours or one year of use, following page 88, then recheck cylinder response with an empty bucket.
Manual Section: Hydraulic System TroubleshootingFrequently Asked Questions
What causes the Gehl V400 lift arms to jerk?
Jerky lift arm and bucket action is typically caused by air in the hydraulic system. To resolve this, cycle the lift and tilt cylinders to their maximum stroke and maintain pressure for a short time to clear the air from the system. p. 100
What is the procedure for jump-starting the Gehl V400?
Jump-starting requires two people to perform the procedure safely. Connect the positive (+) jumper cable to the positive (+) remote battery terminal on the disabled loader first, then to the jumper vehicle's positive terminal. Connect the negative (-) cable to the jumper vehicle's negative terminal, and finally to the negative (-) remote battery terminal on the disabled loader. p. 49
What torque does the All-Tach pivot need on the Gehl V400?
The All-Tach pivot should be torqued to 380 ft.-lbs. (515 N·m) every 250 hours. p. 89
What is the capacity of the engine oil for the V400?
The engine oil capacity for the V400 is 11.75 U.S. quarts (11,1 L). p. 67
What is the correct tire pressure for 14 x 17.5 Heavy-Duty Flotation tires on a Gehl V400?
The recommended inflation pressure for 14 x 17.5 12-ply or 14-ply Heavy-Duty Flotation tires is 65 psi (450 kPa). p. 91
