Case 2090, 2290, 2390, 2590, 2094 Workshop Manual

You are on the job with a Case 2590 that won’t start. You’ve already swapped a filter and bled the fuel system, but the injection timing is off. Without the factory spec, you’re guessing – and guessing on a diesel that size costs you a pump rebuild. I’ve torqued enough head bolts to know: a generic manual from some third party will leave you chasing ghost issues. This is the OEM Case 2090, 2290, 2390, 2590, 2094 Workshop Manual – 118 pages of the same documentation a dealer tech uses. It covers the 2090, 2290, 2390, 2590, and the 2094/2294/2394/2594 variants. No aftermarket interpretation. Just the factory procedures that match the hardware on your lift.

Engine Overhaul: Cylinder Heads and Sleeves

Page 43 holds the torque sequence for the cylinder head bolts. That sequence matters – I’ve seen warped decks from a rookie running them in the wrong order. The manual calls out the step pattern and the final angle, not just a number. Cylinder sleeve removal and installation is also covered, with the puller tool specs listed. You get the clearance for the sleeve flange and the block bore. This is the difference between a seal that holds and a coolant leak that sends you back in.

Hydraulic System: Testing and Filters

Hydraulic pressure testing starts on page 223? Actually, the indexing uses paragraph numbers (see page 02-04 for the index key). The section on “Testing Pumps” and “System Filters” runs from the Hydraulic System chapter (starting around page 269). You will find the pressure specs for the remote valves and the hitch control valve. If you are chasing a slow lift or a drifting rockshaft, the manual gives you the exact port to tap and the gauge range required. Aftermarket manuals skip these details – they tell you “check pressure” but leave out the adapter fitting. This manual includes the Manual Transmission pump pressures for the power shift models, which is separate from the hydraulic system.

Fuel System: Bleeding and Injection Timing

Page 75 covers injection pump timing for the Case 2390 and 2590. That’s the page you need when the engine smokes at idle or lugs hard under load. The manual shows the timing pin location and the degree marks on the flywheel. Fuel system bleeding procedure is on page 73 – a step-by-step that tells you which bleed screw to crack first and which filter housing to prime. If you are using a generic manual, you might Manual Transmission the fuel line order and get air locked. This one gets it right.

Electrical System: Alternator and Starting Motor

Page 94 and 96 cover the alternator regulator test and starting motor overhaul. The wiring diagrams are not just generic schematics – they reference the actual harness connectors on the 2090 and 2094 cabs. You get the diode check procedure for the alternator and the starter solenoid continuity test. I have seen a lot of time wasted replacing a starter that was fine because the ground cable was corroded. The manual’s diagnostic steps make you check the voltage drop before pulling the starter.

Source Validity: OEM Versus Aftermarket

This is the original Case / International Harvester shop manual. The PDF is scanned from the factory print, not a rekeyed copy that introduces typos in torque values. Every page, from the identification plate location (page 05) to the power shift overhaul (pages 124-127 in the index), is verbatim from the OEM. The page count is 118 pages – that covers the 2090, 2290, 2390, 2590, and the 2094/2294/2394/2594 variants. Aftermarket manuals often compress the content into 60 pages and miss the small-block differences. This one has the full index with paragraph references so you can jump straight to the procedure for your specific model.

Audience Fit: Who Needs This Manual

If you own a Case 2290 or 2590 and do your own repairs, this manual pays for itself the first time you avoid a tow to the dealer. The procedures assume you have basic mechanic skills – you know which end of a wrench to use – but they don’t skip steps. Each section lists the required tools, including special Case tools (like the injector puller). For a shop that sees multiple models, the index at page 02-04 gives you model-specific paragraph numbers so you can find the right procedure for a 2090 vs a 2390 without flipping through the whole book.

FAQ

Does this manual cover the Case 2094 model?

Yes. The title includes 2094, and the index lists separate paragraph numbers for the 2094/2294/2394/2594 models. For example, the front axle section shows specific entries for the 2094 under Spindles and Wheel Bearings.

What torque values are listed?

You get factory torque specs for cylinder head bolts (page 43), main bearing cap bolts, connecting rod nuts, flywheel bolts, and wheel lug nuts. The manual also specifies the angle-tighten steps where needed. Not just a generic range – exact ft-lbs for each fastener.

How many pages is this manual?

118 pages.

Is this the same manual a dealer would use?

It is the exact same content. The document is an OEM shop manual distributed by Case/International for their dealer network. It includes the identification plate locations, special tool numbers, and the bleeding procedures that are not found in condensed aftermarket versions. If you want to verify part numbers or compare with the factory parts catalog, this is the source.

You need the factory data on your bench, not a third-party summary. This is the manual that will keep you from guessing torque on a head gasket or mis-timing an injection pump.
