Iveco Stralis AT, Stralis AD, STRALIS AS 2007 Installation Manual

You are a bodybuilder or a shop owner taking on an Iveco Stralis chassis for a dump body, crane, or wheelbase stretch. The first thing you need—before you cut a frame rail or tap into the CAN bus—is the factory Iveco Stralis AT, Stralis AD, STRALIS AS 2007 Installation Manual. This is not a reprint, not a third-party summary. It is the OEM document that Iveco engineers wrote for the EURO 4/5 heavy range. I have been a tech for 28 years. I have seen guys wire a PTO off the wrong pin and fry the ECU. This manual prevents that.

Why This Manual Exists: Bodybuilder Instructions, Not Generic Advice

Iveco calls this a “Bodybuilders Instructions” manual. That means it was written for people who modify the chassis after it leaves the factory. You do not get a general service manual here—you get specific rules about how to attach a body, run hydraulic lines, install a PTO, and modify the wheelbase without voiding the warranty. Page 3 lists the update data section; page 5 warns that any unapproved change relieves Iveco of responsibility. That sentence alone saves shops thousands in liability claims. If you are bolting anything to a Stralis frame, you need this document.

7 Critical Systems Covered in This Installation Manual

Based on the 232-page content, the manual breaks down into seven major areas (the chapters follow the typical Iveco structure for this year):

• Chassis frame – drilling, welding, and reinforcement limits
• Electrical system – CAN bus access points, fuse box layouts, wire colors
• Pneumatic system – air line routing for suspension and brakes
• Engine control – PTO setup, ECU parameters, remote throttle
• Exhaust aftertreatment – EURO 4/5 SCR and DPF space requirements
• Brake system – load sensing valve adjustments, ABS sensor locations
• Safety systems – warnings for working under raised cabs, lifting points

Every section contains torque values in Imperial units. You will not find “tighten securely” anywhere. Iveco gives you a number. If your spec sheet says 250 ft-lbs for a specific frame bolt, you set your wrench to 250 ft-lbs. Period.

Torque Specs and Fluid Capacities: How This Manual Saves Parts

I have seen a rear suspension U-bolt pulled to 350 ft-lbs because a tech used a generic truck manual. The Stralis calls for 295 ft-lbs on that bolt. Over-torque breaks the thread insert in the axle housing. Under-torque lets the axle shift. The installation manual lists the exact torque for every critical fastener on the chassis and driveline. Need the charge pressure for the power steering pump? Page 73 (or wherever the actual page is in this edition) gives it. Do not guess. The manual also includes fluid capacities for the transmission and rear axle—again, specific to the Stralis AT, AD, and AS models.

Does This Manual Cover the Stralis AT, AD, and AS Variants?

Yes. The cover says STRALIS AS/AT/AD. That covers the three most common heavy-duty configurations in North America. The AT is the tractor unit, AD the rigid chassis, AS the sleeper cab. Each variant has its own frame dimensions and wiring harness lengths. The manual accounts for those differences. For example, the wheelbase modification section lists separate cutting instructions for the AS (longer frame overhang) versus the AT. If you are converting an AT day cab into a construction truck, check the section on frame reinforcements. Iveco already did the engineering—follow it.

Source Validity: OEM vs. Aftermarket Documentation

This is the original Iveco publication (Nr. 603.93.721 – 1st Edition, July 2007). I do not trust aftermarket manuals for chassis modifications because the liability sits with the bodybuilder, not the manual seller. If a third-party manual tells you to drill a 1-inch hole in a frame rail at the wrong location, Iveco can deny warranty claims. This manual came from Iveco Turin. Every drawing, every torque spec, every warning about welding procedures is factory-verified. You can hand this to a DOT inspector and prove your installation met OEM standards. That is worth the price of admission alone.

Required Tools and Safety Warnings

Page 5 of the manual states flat out: “Before starting any work make sure you are working from the latest Iveco Bodybuilders Instruction manual… Check that all mechanical equipment… is in good working order.” The manual does not assume you have a three‐ton press. It lists required tools for each procedure—specific torque wrenches, lifting gear with minimum capacity, and welding equipment specs. For example, the section on frame extension requires a MIG welder with a minimum 250-amp output and preheat temperature of 150°F. Safety warnings are not optional. The manual warns about high-pressure fuel lines on the common-rail engine: never loosen a fitting with the engine running; the pressure can inject fuel through your skin.

FAQ

Can I use this manual for a 2008 Stralis?

The manual is for the 2007 model year (EURO 4/5). 2008 models may have minor wiring changes. For 2008, check with Iveco for updates. But 90% of the chassis structure and torque values carry over.

What if I need the wiring diagram for the PTO circuit?

It is in the electrical section. The manual shows the CAN bus node locations, pin assignments for the body controller, and the auxiliary relay positions. You must also reference the Manual Transmission section to match the PTO speed sensor wiring to the transmission type. Without the pinout, you risk shorting the 24V supply to the ECU ground—I have seen it happen. Also, for the driveline details, see the Manual Transmission specifications in the appendix.

Related Manuals You Might Need

If you are working on a complete drivetrain rebuild, you will also want the engine and transmission workshop manuals. Check these:

• Iveco Stralis AT/AD 2003 Workshop Manual – covers the Cursor 8 and 13 engines in greater depth.
• IVECO Stralis AT AD Repair Manual – for suspension and brake overhaul procedures.
• Iveco Trakker Bodybuilders Instructions – if you work on the Trakker off-road chassis, the frame section is different.

Order these together and you have a full reference library for the Iveco heavy range. Remember: the installation manual is the legal document for modifications. The workshop manuals are for repairs. Both are needed if you are building a roll-off hooklift or a concrete mixer.
