Linde H12, H16, H18, H20 Training Manual – What You Actually Get

I’ve seen too many forklift repair jobs go sideways because someone relied on a generic hydraulic diagram or a reprint that left out the critical shim tolerances. The Linde H12, H16, H18, H20 Training Manual is the real deal – a factory document from Linde AG, not some third-party rewrite. If you’re working on a Series 350 IC-engined truck with Linde Hydraulic Control (LHC), this is the only paper that should be on your bench. It runs 238 pages, covers H12, H16, H18, and H20 variants, and gets into the kind of spec detail that separates a running truck from a comeback job.

Engine Specifications and Timing (Chapter 1)

First section opens with diesel engine specs – displacement, compression ratios, valve clearances. But the meat is in the injection pump work. Section 1.3 walks you through removal and installation of the fuel injection pump, then checking and adjusting static injection pump timing. Page 8 has the exact procedure for setting pump timing with a dial indicator. It also covers crankshaft sprocket removal and alternator V-belt tension adjustment. If you’re chasing a hard-start or low-power issue, this chapter will save you from pulling parts you don’t need.

Transmission and LHC Control (Chapter 2)

Chapter 2 is where the hydraulics get dense. Starts with the digital electric-hydraulic control (LHC) – general layout, then how the electronic control manages truck speed. There’s a schematic diagram of the drive unit (page 4) and a full hydraulic circuit diagram (page 7). Technical data for the travel drive system is listed on page 5. You’ll find cross‑sectional views of the drive pump and the variable pump. The manual doesn’t skip the electric‑hydraulic adjustment procedure (section 2.7) – including how to set the swash angle and the hydraulic zero position. A towing device procedure is also in here.

Diagnostics: Working with the Linde Test Module (Section 2.10)

Diagnostics are broken out in section 2.10. It covers electrical system diagnostics, then gets specific about using the Linde Test Module – the factory scan tool. There’s also a subsection on diagnostics with a PC using the Linde Interface Converter and the “Test & Setup” software installation. If you’re dealing with intermittent fault codes or a dead control unit, this part tells you which pins to probe and what readings to expect. Standard aftermarket manuals skip this level of detail. You’ll also find troubleshooting tables for common hydraulic and drive system issues.

Hydraulic Circuit Diagram – What You Need to Know

Page 7 shows the hydraulic circuit diagram. This isn’t a generic representation – it’s the exact plumbing for the Series 350 trucks with LHC. The diagram includes the variable pump, brake valve, and multiple disc brake circuit. If you’re swapping a drive motor or rebuilding a reduction gear, you’ll need to reference this diagram to avoid cross‑connecting lines. The manual also covers repairing the reduction gear, multiple disc brake, and hydraulic motor (section 2.9).

Does This Manual Cover the Glow Plug System?

Yes, section 1.6 covers the glow plug system – checking glow plugs, testing them, and what burnt electrodes mean. It’s two pages but saves you from chasing a no‑start in cold weather. The same chapter also has compression pressure checking and hydraulic tappet inspection. For a 238-page training manual, it packs in more real repair procedures than most aftermarket service books that claim to be “comprehensive.”

5 Systems You’ll Actually Fix Using This Manual

• Diesel engine – injection timing, cylinder head removal, crankshaft timing
• Transmission – LHC electronic control adjustment, drive pump repair
• Hydraulics – circuit diagrams, variable pump cross-section
• Electrical diagnostics – Linde Test Module and PC interface
• Drive axle – reduction gear, multiple disc brake, hydraulic motor

Source: OEM Linde, Not a Reprint

This is a scan of the original Linde training document – part number 350 804 4701.0400. It’s marked “Service Training” and remains exclusive property of Linde AG. That means every torque value, every shim thickness, every diagnostic voltage matches what the factory expects. I don’t trust aftermarket wiring diagrams for anything with a hydrostatic drive. This manual gives you the OEM specs, period.

Who Needs This Manual?

If you’re a shop owner or a fleet mechanic who sees H12 to H20 Linde trucks regularly, this training manual belongs in your library. For DIY owners, it’s the difference between guessing and knowing. The instructions assume some mechanical understanding, but they’re written for technicians – no fluff, just the steps. Page 26 covers the multiple disc brake removal and installation sequence; you’ll need that if you’re replacing internal seals.

What torque specs are given for the cylinder head?

Section 1.5.5 covers fitting the cylinder head with tightening sequence and torque values. The manual lists the exact values for the Series 350 engines.

How many pages does the manual have?

238 pages. That includes the table of contents and all chapters.

Does it include the LHC diagnostic software setup?

Yes – section 2.10.1.2 covers installation of the “Test & Setup” diagnostic software and use of the Linde Interface Converter.

Is this only for the H12, or does it cover the larger models too?

The manual specifically covers H12, H16, H18, and H20 trucks – all part of the Series 350 family. It does not cover H25 or larger.

Access the Factory Manual now and keep a copy on your shop tablet. Having the OEM training material in front of you when you’re pulling an injection pump or adjusting the LHC hydraulic zero will pay for itself on the first job.
