Terex T45, T45X, T45S Service Manual – Factory Maintenance Specs

If you’re wrenching on a T45, T45X, or T45S reachstacker and you don’t have the factory torque values for the hydraulic fittings, you’re gambling with a $200,000 machine. I’ve seen too many guys snap bolts or blow seals because they used a generic chart. That’s why you need the Terex T45, T45X, T45S Service Manual – not a third-party reprint, the OEM document from Terex. 103 pages of exactly what the factory expects you to do, when, and with what tool. Exactly the procedure they wrote for their own techs.

This manual covers the maintenance of the Reachstacker T45, T45X, and T45S. It’s a translation of the original Italian instructions, so the torque table on page 21 uses Nm, but there’s a conversion table to Imperial right there. You get sections on general information, routine maintenance, extraordinary maintenance, troubleshooting, and transport. It tells you how to fill out the control logbook, how to inspect hydraulic oil systems, and exactly which filters to replace and when. That’s the difference between a machine that runs for 10,000 hours and one that gets a rebuild at 4,000.

Terex T45, T45X, T45S Service Manual: What’s Inside

Start with Section 1 – General Information. It covers ground personnel safety, general warnings related to maintenance, and the control logbook. There’s a sample logbook and instructions on how to fill it out. Then it dives into system maintenance: preventive maintenance, inspection, restore, and maintenance programming for hydraulic oil systems and electrical systems. The screw tightness torque table on page 21 is a must-have. You get a conversion table for inches-millimeters, volume, pressure, speed, temperature, length, power, and strength. That’s the kind of data you don’t want to approximate.

Screw Tightness Torque Table: Why You Need It

Page 21 has the torque table. It lists values for different bolt grades and sizes. If you’re tightening a hydraulic fitting on the pump-transmission compartment, you need that number. The manual also includes pressure adjustment and measurement points located in the main right compartment and the secondary right compartment. On page 46, you’ll find the pressure control points – that’s where you set the pressures for the hydraulic circuits. Without those specs, you’re either under-tightening or over-tightening, and both cost you time and money.

Hydraulic Oil System Maintenance: Inspection and Restore

The hydraulic system is the heart of this reachstacker. Section 1 has a sub-section on hydraulic oil systems: inspections, maintenance, restore, eliminating malfunctions, and restoring components. It tells you how to check oil level, where the level indicators are (page 37), and how to top up. For the T45X and T45S, the procedures are the same. The manual also covers the cooling oil bath brakes – checking oil level and topping up. That’s critical for the brakes on these machines. Don’t skip it. The routine also includes checking junction tightness, inflating tyres, and adjusting movement sliders – all with factory-specified tolerances. If you’re rebuilding a hydraulic pump or replacing a valve, the restore procedures will save you from contamination issues.

Routine Maintenance: Control List and Lubrication

Section 2 – Routine Maintenance – gives you a control list for maintenance and a TABLE OF CONTROLS on page 27. That’s your schedule. Lubrication table on page 29 tells you which grease points to hit and with what lubricant. The routine maintenance procedure includes checking engine oil level, coolant level, transmission oil level, hydraulic oil level, and filling the diesel oil tank (800 litre capacity). There’s even a section on refilling the AdBlue tank only with Volvo TAD1360VE engine. The manual shows you the position of all caps and level indicators. If you’re servicing a T45, you need this for the differential axle and wheel hub oil changes. It also covers programmed replacement of filters, coolants, and sliders. That’s the kind of detail that keeps a reachstacker working in a busy yard without unplanned downtime.

Troubleshooting Section: Diesel Engine and Braking System

Section 4 – Troubleshooting – covers the diesel engine, maximum pressure valve, check valve, direction adjustment valves, pressure adjustment valve, filters, pressure gauges, gearbox and torque converter, steering, overload control system, and braking system. If the machine throws a code or something feels off, you go here first. The manual doesn’t tell you to replace parts randomly – it walks you through the diagnosis. That’s the OEM way. For more on manual transmission diagnostics, check Manual Transmission and Manual Transmission for general principles, but for the T45 series, this manual is your only reference for factory-specific values and component locations.

Who This Manual Is For

If you own a T45, T45X, or T45S reachstacker, this manual is for you. Whether you’re a fleet mechanic, a rental yard tech, or a contractor who maintains your own equipment, you need the factory procedures. This is not for the casual DIY guy – these machines are big and dangerous. But if you have the training and the tools, this manual gives you the specs to do the job right. The section on pressure control points (page 46) alone will pay for the manual the first time you adjust the hydraulics without blowing a seal. You also get the electrical system maintenance and restore procedures – critical for avoiding shorts and component failure.

Source Validity: OEM vs Aftermarket

This is the OEM manual from Terex. It’s the same document that Terex sends to their dealerships. The parts catalog TEREX T45 Parts Catalog and the operator manual TEREX T45 T45X T45S Operator Manual complement this service manual. If you need specs for an older Terex machine like the TS14G, check Terex TS14G 1994 Service Manual – Factory Specs for Overhung Scraper. But for the T45 series, this is it. Aftermarket manuals often skip the detail on the control logbook and the conversion tables. Don’t trust a copy when you can have the original.

Frequently Asked Questions

Does this manual cover the Volvo TAD1360VE engine?

Yes, it covers the Volvo TAD1360VE engine in Section 2 for AdBlue refilling and oil top up.

Can I use this manual for the T45X or T45S?

Yes, the manual explicitly covers T45, T45X, and T45S models. All sections apply to all three, unless otherwise noted (e.g., AdBlue only for Volvo engine). The torque table and pressure points are the same across models. Additionally, the routine maintenance procedures such as checking oil levels, lubricating sliders, and replacing filters are identical for all variants. The only differences are in specific engine types and optional equipment. For example, the diesel engine oil top up differs between Cummings and Volvo engines, but both are covered. The control logbook example is generic and applies to any of the three models. So yes, this single manual serves all T45 series reachstackers.

If you want to keep your T45, T45X, or T45S reachstacker running at factory spec, there’s only one way to get the procedural detail and the torque values: Access the Factory Manual from AutoRepairManuals. It’s 103 pages of OEM maintenance that will save you from a blown hydraulic line or a seized transmission. I’ve seen techs waste hours because they didn’t have the right pressure settings. Don’t waste your time. Get this manual in your service bay and use it on every job.
