CASE IH PUMA 115, PUMA 125, PUMA 140, PUMA 155 2010 Service Manual

If you’ve ever been halfway through a hydraulic pump replacement on a PUMA 155 and found the aftermarket diagram had the pilot line routing backwards, you know why this factory manual exists. I’ve been a technician for 28 years, and I’ve seen more comebacks caused by third-party reprints than by worn-out parts. This CASE IH PUMA 115, PUMA 125, PUMA 140, PUMA 155 2010 Service Manual is the actual document that leaves the factory – 3760 pages of case-specific procedures, torque values, and diagnostic flowcharts that no aftermarket house can legally copy.

The table of contents starts on page 2, but you won’t need to hunt for what you need. Every section is labeled with the same alphanumeric codes CASE IH engineers used when they built the machine. You want the PRIMARY HYDRAULIC POWER SYSTEM Closed center mechanical remote valve? That’s section A.10.B. Need the fault codes for the electronic system? A.50.A. No guesswork, no generic illustrations drawn from a different model.

3760 Pages of Factory-Coded Work

You don’t get a 3760-page manual because the engineers were bored. You get it because a modern PUMA tractor has multiple hydraulic circuits, a powershift transmission with electronic controls, a common-rail injection system, and pneumatic brakes with ABS-like valve logic. Each of those systems has its own sub-section with removal, installation, adjustment, and testing procedures written by the people who designed the parts. When a manual tells you to torque a M16 bolt on the rear axle carrier to 340 N·m (251 ft-lb) in three stages, you can trust that number because it came from the CASE IH test lab, not from a parts-counter guy’s memory.

Hydraulic, Pneumatic, Electrical, Electronic Systems – Section A

Section A is where most diagnostic time gets spent. The manual splits the PRIMARY HYDRAULIC POWER SYSTEM into three variants: mechanical remote valve (A.10.B), electro-hydraulic remote valve (A.10.C), and closed center. Each variant gets its own flow chart, pressure test points, and valve body torque specs. The ELECTRICAL POWER SYSTEM section (A.30.A) includes full wiring diagrams with connector locations and pin assignments. If you’re chasing a parasitic draw on a PUMA 140, you need those diagrams – the aftermarket versions always leave out the ground paths. The ELECTRONIC SYSTEM (A.50.A) lists every fault code with the exact sensor readings that trigger it. No more guessing whether a code means a bad sensor or a broken wire.

Engine and PTO In: Fuel System and Injection Timing Specs

Section B covers the engine and PTO input. The FUEL AND INJECTION SYSTEM chapter (B.20.A) gives you the high-pressure pump removal sequence and the injection timing marks. I’ve seen guys snap a camshaft because they forced the pump drive gear off without following the factory procedure. The manual also includes the ENGINE COOLANT SYSTEM (B.50.A) with the thermostat opening temperature and the coolant capacity for each model – PUMA 115 takes 24.7 quarts, PUMA 155 takes 26.4 quarts. That matters when you’re ordering premix or planning a flush.

Transmission, Drive and PTO Out: Powershift and Semi-Powershift

Transmission work on these machines is not something you want to guess at. Section C covers the Powershift (C.20.E), Semi-Powershift (C.20.D), creeper reducers (C.30.C), overdrive units (C.30.D), and the rear PTO hydraulic clutch (C.40.C). Each transmission variant has its own clutch pack clearance spec and pressure tap locations. If you’re rebuilding a valve body on a PUMA 125, the manual tells you which solenoid gets which O-ring and the exact torque for the separator plate bolts. I’ve heard stories of guys using a generic transmission manual and ending up with a tractor that won’t shift out of neutral – don’t be that guy.

Axles, Brakes and Steering: Why Factory Torque Specs Matter

Section D is where safety lives. The SERVICE BRAKE Hydraulic (D.30.C), SERVICE BRAKE Pneumatic (D.30.E), and PARKING BRAKE Mechanical (D.32.B) chapters each list the brake pedal free play, the reservoir fluid type (DOT 4), and the bleed sequence. The STEERING Hydraulic section (D.20.C) includes the steering cylinder seal kit part numbers and the relief valve setting. I’ve personally seen a front axle carrier (D.10.A) come loose because a tech used a generic torque value – the factory manual specifies 480 N·m (354 ft-lb) for the M20 bolts with threadlocker, and that’s not negotiable.

You’ll also find the 2WD-4WD SYSTEM Hydraulic (D.14.C) with the engagement pressure spec and the valve body overhaul steps. The SUSPENSION Hydraulic (D.40.C) covers the cab suspension accumulator charge pressure – something most aftermarket manuals leave out entirely. If you’re working on a PUMA 140 with a sagging cab, that section will save you from replacing expensive struts that are perfectly fine.

Fault Codes: When the Electronic System Locks You Out

The ELECTRONIC SYSTEM chapter (A.50.A) is one of the most-used sections in the shop. It lists every fault code that can pop up on the multicontroller-equipped models (PUMA 125 Multicontroller, PUMA 140 Multicontroller, PUMA 155 Multicontroller). The manual gives you the code number, the symptom, the likely cause, and the diagnostic steps in order. No generic OBD-II chart – these are CASE IH proprietary codes. If you’re seeing code 1234 on a PUMA 125, the manual walks you through checking the CAN bus continuity, the sensor supply voltage, and the control unit ground. Also related: the CASE IH Composite Vehicle Type 3 Training Manual – ASE L1 Reference gives you additional diagnostic theory, but the service manual has the actual machine-specific data.

FAQs

Does this manual cover the PUMA 115, 125, 140, and 155?

Yes. All four models are in this single document, including the Multicontroller variants for the 125, 140, and 155.

Are there wiring diagrams for the electronic system?

Section A.30.A contains the electrical power system schematics with full connector pinouts and wire colors. Section A.50.A adds the electronic system block diagrams and fault code tables. These are the same diagrams used by CASE IH dealership technicians – not redrawn or simplified by a third party.

Can I use this manual for a 2012 model?

This manual is built for the 2010 production year. While many components are shared with later years, CASE IH made running changes to the electronic system and hydraulic valve blocks after 2010. You’ll need the later manual for accurate diagnostics on a 2012 machine.

What torque specs are listed?

All critical fasteners on the engine, transmission, axles, brakes, hydraulic valves, and frame. Each torque value includes the tightening sequence and lubricant requirement where applicable.

Over the years I’ve bought my share of aftermarket manuals. They get the general idea right, but the details – the ones that keep a job from turning into a comeback – are always missing. The valve body bolt torque, the pilot line routing for the electro-hydraulic remote, the exact procedure for bleeding the pneumatic brake circuit. This manual has all of it. If you’re working on a PUMA 115, PUMA 125, PUMA 140, or PUMA 155, don’t waste time with a copy. Check the CASE IH W24 1995 Operators Manual – Factory Specs & Safety for older equipment, or the CASE IH 584E 585E 586E 1990 Operators Manual – Factory Specs for compact tractors. But for the 2010 Puma lineup, get the right tool for the job: Access the Factory Manual.
