Part of the Case Repair Manuals.
All 474 pages of this Case NEF Tier 3 Service Manual (OEM #84250518) cover the complete engine family: F4CE9484, F4CE9684, F4DE9484, F4DE9684, F4DE9687, F4GE9484, F4GE9684, F4HE9484, and F4HE9684. Inside you'll find wiring diagrams for the electrical power system, exploded views of the lubrication circuit and fuel injection assemblies, and system diagrams spanning the coolant, air intake, exhaust, and starting systems. You also get a dense procedures section walking through valve drive, crankshaft, cylinder head, and high-pressure common rail service, backed by a full torque table and special tool index right in the front matter. Torque the M10 belt tensioner to 37-49 Nm; replace the fuel filter with tool 380000670 at 10-15 Nm. No more chasing engine specs across three different sources. Bookmarked and keyword-searchable, pull it up on your phone or tablet right at the machine.

Case NEF Tier 3 (F4CE–F4HE) Common Problems This Manual Covers
Case NEF Tier 3 engine torn or worn drive belt with heavy lubricant or fuel contamination p. 10
Inspect the front cover area for fluid leaks. Replace the damaged belt and verify the belt tensioner torque is 37 - 49 Nm (27.3 - 36.1 lb ft) as detailed on page 10. Clean all pulleys thoroughly before installing the new belt.
Manual Section: Power Production - EngineMomentary or complete engine stoppage with a low oil pressure warning or coolant temperature alarm p. 10
Drain the oil and replace the oil filter. Apply clean oil to the new gasket and tighten the filter to contact plus a 3/4 turn, referencing page 10. Refill the system with fresh oil and check the coolant expansion tank sensor for proper operation.
Manual Section: Power Production - Lubrication SystemFrequent leaks from fuel circuits and filter housings with low fluid levels or air ingestion p. 100
Remove the old fuel filter and clean the mounting base. Install the new filter using tool 380000670 and torque it to 10 - 15 Nm (7 - 11 lb ft) according to page 100. Bleed the fuel circuit completely before attempting to restart.
Manual Section: Power Production - Fuel and Injection SystemSquealing noise from the front accessory drive or loose alternator belt during cold engine starts p. 11
Check the idler pulleys for bearing play. If replacing the pulleys on F4CE or F4GE models, torque the M10 fasteners to 37 - 49 Nm (27.3 - 36.1 lb ft) as shown on page 11. Verify pulley alignment to prevent premature belt wear.
Manual Section: Power Production - EngineFrequently Asked Questions
What are the recommended service intervals?
The manual provides a table for regular maintenance and inspection planning. For instance, the replacement of engine's oil and filter is recommended every 500 hours, while the replacement of the belt is every 1500 hours. Inspection and setting of tappet clearance should be done every 4000 hours.
What fluids and capacities does this machine require?
For 4-cylinder engines, the oil pan capacity is 13 l (13.7 US qt) and the oil filter capacity is 1 l (1.1 US qt). For 6-cylinder engines, the oil pan capacity is 15 l (15.9 US qt) and the oil filter capacity is 1 l (1.1 US qt).
What are the hydraulic system specifications?
The fuel injection system incorporates a hydraulic system with a rail delivery pressure modulated between 250 - 1600 bar (3625 - 23200 psi) by the electronic control unit. The pressure relief valve on the high pressure pump maintains a constant pressure of 5 bar (73 psi) at its inlet.
What torque specifications are listed?
Various torque specifications are listed for engine components. For example, the Cylinder Head Plug (¼") requires 10 - 14 Nm (7.4 - 10.3 lb ft), and the Intake Manifold M8 Screw requires 20 - 28 Nm (14.8 - 20.7 lb ft). The Engine Lifting Bracket Rear M12 bolts should be tightened to 65 - 89 Nm (47.9 - 65.6 lb ft).
