DAF LF45, LF55 2010 Workshop Manual

If you are wrenching on a DAF LF45 or LF55 from 2010, you already know that aftermarket documentation is a gamble. I have seen guys snap bolts on cab tilt assemblies because some third-party PDF had the wrong tightening torque. That costs you time, parts, and a phone call to the customer. The DAF LF45, LF55 2010 Workshop Manual is the OEM file – 230 pages of factory procedures, not a reprint of a reprint. It covers the cab suspension, tilt gear, seats, and all accessories. This is the same book DAF dealers use.

Factory data is the only data that matters.

Cab Suspension: Factory Torque Specs

The cab suspension on these trucks uses air bags and dampers. Page 2-3 lists the tightening torques for every bolt in the suspension assembly. If you are replacing the cab suspension struts or the anti-roll bar, you need those numbers. I have seen what happens when someone guesses: cracked brackets and a cab that leans. The factory manual gives you lb-ft values for each fastener. No guesswork.

Tightening Torques Across the Manual

Every section has a dedicated tightening torque sub-chapter. The cab tilt gear section specifies filling capacities on page 3-1 as well. If you are servicing the hydraulic tilt pump, you need to know the correct fluid level and type. The manual tells you. The ACCESSORIES section also lists its own torques on page 5-2. Aftermarket manuals often lump all cab-related fasteners into one table. That is lazy and dangerous. The DAF factory manual separates them by system because each system has different materials and load requirements. The INTERNAL AND EXTERNAL CAB COMPONENTS chapter has its own torque table on page 1-8. You get that level of granularity throughout the 230 pages.

Diagnostics Section: What It Covers

This manual includes a DIAGNOSTICS chapter that walks you through fault codes and test procedures specific to the LF45/LF55 cab electronics. It is not a generic scan tool guide; it references DAF-specific wiring and component locations. If you are troubleshooting a cab heating issue or a seat adjustment problem, the diagnostics section gives you a step sequence that matches the factory service protocol. For deeper electrical troubleshooting, the DAF LF/CF/XF Series Diagnostics Manual is a good complement.

Who Should Use This DAF LF45 LF55 Workshop Manual

This manual is for anyone who is working on these trucks, whether you are a seasoned fleet mechanic or an owner-operator who does his own maintenance. The procedures assume you have basic mechanical skill but they give you the factory step sequence. For example, the cab heating section walks you through removing the heater core without damaging the dashboard trim. The seats chapter tells you how to adjust the suspension seat. DAF LF45 LF55 2004 Technical Manual is a predecessor but this 2010 version includes updates to cab components and suspension. DAF LF45 LF55 Gearboxes and Clutch Workshop Manual covers drivetrain separately. If you need a broad overview of [Manual Transmission] theory, the Manual Transmission page on Wikipedia is useful, but for specific DAF LF45/LF55 torque values, stick with this OEM manual. Manual Transmission references can help with general understanding, but don’t rely on them for assembly.

Source Authenticity: OEM vs. Aftermarket

This manual is a direct scan of the DAF factory publication with part number © 0210. It is not a third-party rewrite. Every spec comes from DAF engineering. I have been burned by aftermarket manuals that swap metric and imperial units. This one uses the same units as the factory line. The TECHNICAL DATA section at the start gives you vehicle identification numbers, axle ratios, and weight tables specific to the LF45 and LF55. That information matters when you are ordering parts or calculating spring rates for the cab suspension. Trust the factory document, not a generic PDF.

Does this manual cover the engine or transmission?

No. This manual focuses on cab and accessories only. Engine and drivetrain are separate documents.

What torque values are listed for the cab suspension?

Page 2-3 lists the tightening torques for all cab suspension fasteners, including the air bag bracket bolts, damper mounts, and anti-roll bar connections. Each fastener is specified with its exact lb-ft value, and the manual also notes whether to apply threadlocker or lubricant. Without those numbers, you risk over-torquing the air bag studs – I have seen that cause leaks within 500 miles. The factory also gives the sequence for tightening the anti-roll bar, which prevents twisting the bushings. This is the kind of detail you only get from an OEM document like this 230-page workshop manual.

If you are going to work on a DAF LF45 or LF55 from 2010, get the factory data. Shop manuals like this one keep your repairs correct and your customers safe.
