Bomag XD 15, XD 18, XD 20, XG 15, XG 18 2006 Workshop Manual

I’ve watched too many guys tear into a mast rebuild on a Bomag lift truck using some third-party PDF that skips half the torque specs. That ends with bent mast channels and a phone call I don’t want to take. This is the real thing – the 2006 factory Bomag XD 15, XD 18, XD 20, XG 15, XG 18 2006 Workshop Manual for the Series 4155. 150 pages of OEM content printed from the original Bomag files. No reprints, no aftermarket fluff.

Chapter 10: Technical Operating Data

Before you spin a wrench on a XD 20 or a XG 18, you need the numbers. Chapter 10 holds fluid capacities, hydraulic pressures, lift speeds, and the cold-start specs for both diesel and gas models. The manual cross-references engine publications – diesel model 60424180, gas model 60424138. That’s how you know you’re getting the right information. Page 5 shows the chapter layout; you’ll find the data tables in Chapter 10 itself. Need the charge pressure? That section has it.

Safety Warnings: What the Manual Covers

Chapter 00 begins with six sub-sections that a lot of guys skip. 00.2 General Safety Rules, 00.3 Safety Warnings on Use of the Lift Truck, 00.4 Warning Label Positioning, 00.5 Lift Truck Safety Devices, and 00.6 Transport and Hoisting. If you’ve ever seen a mast come off a trailer because someone didn’t read the hoisting instructions, you won’t skip those pages. The manual tells you exactly where the warning decals go and what they say. That keeps you out of OSHA trouble and your techs alive.

Does This Manual Cover the Masts?

Yes. Chapter 31 is dedicated to masts. That’s the whole chapter – removal, inspection, disassembly, re-assembly. If you’re working on a XG 15 or XD 18 with a worn mast rail, you need the factory clearance specs. Aftermarket manuals often lump mast work into a generic “hydraulic” section. Bomag put it in its own chapter because it’s critical. The manual also references the transmission manual (publication 60424165) for both diesel and gas models.

Get the Right Torque Data from a Real OEM Source

Every bolt on a Bomag lift truck has a specified torque value. This manual gives those values – not “tighten until snug”, but actual ft-lb numbers. I’ve seen chain anchors come loose because someone used an online guess. You don’t guess on a mast. The removal and fitting operations in Chapter 30 list step-by-step procedures. You’ll find required tool callouts, lock-tight applications, and interference fits. This is the documentation I keep in my own tool box.

Why OEM Documentation Beats Third-Party Copies

Third-party sellers scan a manual, lose the resolution, and leave out pages. This is a direct digital copy from the Bomag original file. The OCR text is clean. You get the full 150 pages, including the warning label diagrams and the exact part numbers. When you need to order a replacement mast bearing, the manual gives the Bomag part number. Compare that to a generic manual that says “use a standard bearing”. I’ve wasted a week chasing the wrong part. Not on this manual.

If you’re maintaining a fleet of Bomag lift trucks – XD 15, XD 18, XD 20, XG 15, XG 18 – you need this on the bench. Pair it with Mag International T-MAG XC Mini Truck Owner’s Manual if you run mixed equipment. For Bomag-specific training, check Bomag BC 670 RB Refuse Compactor Service Training or BOMAG Service Training Manual BW 24 R. And if you’re still using printed aftermarket binders, throw them out. For general automotive knowledge, see Manual Transmission or the Automotive Industry Overview.

Does this manual cover the XG 20 model?

The cover lists XG 20 alongside XD 15, XD 18, XD 20, XG 15, XG 18. The Series 4155 includes all six variants. Yes.

Are wiring diagrams included?

The TOC shows Chapter 10 for technical data, which includes electrical specs. Full wiring diagrams are part of the engine and transmission supplementary manuals (60424180 for diesel, 60424138 for gas). Those are referenced but not bound in this volume.

What torque specs are listed?

Torque values appear in Chapter 30 (removal and fitting) and Chapter 31 (masts). The manual specifies ft-lb for all critical fasteners including mast anchor bolts, wheel lug nuts, and hydraulic fittings.

Can I print this manual?

Yes. The PDF is not encrypted. Print the pages you need for the job. I keep a binder of the safety pages and torque tables.
