Landini Rex 60, Rex 65, Rex 70, Rex 80, Rex 90 2003 Training Manual

You’ve got a Rex 70 that won’t start, a Rex 90 with a clutch that’s slipping, or a Rex 80 that’s dumping hydraulic fluid all over the shop floor. And the aftermarket manual you grabbed online? It tells you to tighten the head bolts to 80 ft-lb, but the Landini factory spec says 74 ft-lb plus a 90-degree turn. That’s the difference between a seal that holds and a head gasket that blows five hours later. I’ve seen it happen. This Landini Rex 60, Rex 65, Rex 70, Rex 80, Rex 90 2003 Training Manual is the actual OEM document used at the Landini training center in Italy. It’s 710 pages of factory data—no translations, no guesswork, no third-party edits. If you’re working on one of these orchard or vineyard tractors, this is the single source you need.

Engine Timing: 903.27 and 1004.40/42/40T

Chapter 2 of the manual covers both engine families. The 903.27 engine tuning section (Sect. 3) walks you through finding compression TDC of cylinder #1, checking camshaft timing, and verifying the injection pump locking angle. For the 1004.40, 1004.42, and 1004.40T engines, Sect. 4 gives the same step-by-step procedure. Each step includes the factory driving torque values—for example, the recommended torques for the 1004.40T are listed in Sect. 2-3. If you’re a tech who’s been burned by aftermarket manuals that skip the injection pump timing, this section alone is worth the price of the access. The manual also includes conversion tables (Sect. 5) so you can convert those metric torque values to ft-lb if you’re working with imperial tools.

Transmission Rebuild: What the Standard Transmission Chapter Covers

Chapter 4 is the standard transmission. The manual doesn’t just give you a drawing—it breaks down the main components into four sub-assemblies: engine-gearbox axle assembly (A), gearbox (B), bevel gear pair and rear differential (C), and side final drives (D). Each sub-section has inspection and adjustment procedures. For the differential, you get the pinion position adjustment relative to the crown wheel, bearing preload specs, and the correct tooth contact pattern. The power train diagram on page [DATA NEEDED] shows the gear layout. If you’ve ever rebuilt a transmission using a generic manual and ended up with a whine that wouldn’t go away, you know why the OEM procedure matters. The manual also includes a section on Manual Transmission theory—though it’s focused on this specific Landini model.

7 Major Systems Documented

The table of contents lists 13 chapters. Here’s what you’re getting: Introduction (safety, pre-delivery inspection, torque values), Engine, Clutch, Standard Transmission, 4WD Front Axle, Power Take-Off, Low Pressure Hydraulic Circuit, High Pressure Standard Hydraulic Circuit, Mechanical Power Lift, Electronic Power Lift, Electrical System, Air Conditioning System, and Special Tools. That’s every major system on the Rex 60 through Rex 90. The hydraulic circuit specs (Sect. 2-9) give you pump flow rates and pressure settings. The electrical system chapter includes wiring diagrams for the whole tractor. No fluff, no reprints—just the 2003 factory training binder.

Get the Right Torque Data Before You Tighten Anything

Torque values are scattered throughout the manual, but the main driving torque tables are in Chapter 1, Sect. 7. The engine-specific torque values are in Chapter 2, Sect. 2. For the transmission, Chapter 4, Sect. 2-3 lists driving torques and sealants. And the clutch chapter (Chapter 3, Sect. 2) gives you the main technical specs including clutch pedal free play. If you’re replacing a clutch on a Rex 65, you’ll find the flywheel bolt torque and the pressure plate bolt torque in that section. Use the correct Loctite sealant from the list in Sect. 6-1. I’ve seen guys skip the Loctite on a PTO shaft and then wonder why it leaks. Don’t be that guy.

Source Validity: Why This Is Not a Reprint

This file is a direct scan of the original Landini training manual, P/N 3659961M2, published May 2003. It’s not a third-party compilation, not a reflowed PDF with missing pages, and not a copy of a copy. The OCR excerpt shows the actual page layouts with the Landini logo and the preface statement that the manual is intended for training center attendees. If you’re serious about working on these tractors, you want the OEM document. Compare it to something like the Landini Legend 2000 Training Manual—that’s a different series, but the same factory quality. For other Landini models, the Landini Legend 105-165 Workshop Manual is also available. And if you’re cross-training on other brands, the Hyundai Kia Transaxle Training Manual might be useful, but it’s not a Landini spec.

A word about the 4WD front axle (Chapter 5). The manual includes the same level of detail: assembly drawings, inspection procedures, and driving torques. If you’re diagnosing a wobble in the front end, you’ll find the wheel bearing preload procedure and the steering knuckle torque specs. The manual also covers the high-pressure hydraulic circuit (Chapter 8) for the power lift. That’s where most of the electrical gremlins live in these tractors, and the wiring diagrams in Chapter 11 will save you hours of chasing shorts.

One more thing: the safety section (Chapter 1, Sect. 3) is not just boilerplate. It covers the specific danger decals on the Rex models, safe lifting procedures, and the correct way to replace tractor parts. If you’re working alone in a home garage, read that section. The manual also explains how to do the pre-delivery inspection (Sect. 4-2) and the routine maintenance guide (Sect. 4-3). That’s the kind of info that keeps a tractor running for 20 years instead of 20 weeks.

FAQ

Does this manual cover the Rex 100?

Yes, the Rex 90 and Rex 100 are included in the “Rex 80-90-100” listings in the engine specs and other sections. The manual covers Rex 60, 65, 70, 80, 90, and 100.

What torque values are in the manual?

Standard driving torques are in Chapter 1, Sect. 7. Engine-specific torques for the 903.27 and 1004.40/42/40T are in Chapter 2, Sect. 2. Transmission and clutch torques are in their respective chapters. The conversion tables in Sect. 5 let you convert between metric and imperial.

Is this the same as the service repair manual?

No. This is a training manual, not a full service repair manual. It includes the same technical specs, torque data, and procedures, but it is designed to be used alongside instructor-led training. It does not contain every repair step for every possible failure—it focuses on the core systems. For a deeper service manual, look at the Manual Transmission chapter here is thorough, but overall the training manual is a complement to a workshop manual.

Can I print this manual?

The PDF is full quality and can be printed. 710 pages is a lot of paper, but if you need a hard copy in the shop, go ahead. The file is a scanned original, so the images are clear.

Look, I’ve been turning wrenches since before most of these tractors were built. When you’re up against a deadline and a customer’s tractor is sitting in the yard, you don’t have time to guess. You need the factory data. That’s what this Landini Rex 60-90 2003 Training Manual gives you. Access the Factory Manual and get the job done right the first time.
