Kramerallrad 180, 280 2007 Service Manual

You’re pulling a wheel loader into the bay. It’s a Kramerallrad 180, 280 2007 Service Manual job – and if you’ve ever tried to guess a torque spec on a steering ram or guess which hydraulic circuit feeds which motor, you know where that ends. Stripped threads, blown seals, hour wasted. This is the factory manual, 238 pages of what Kramer-Werke printed in 2007. Not a reprint, not a third-party copy. Original OEM.

I’ve torqued more head bolts than most people have had hot meals. When I need a spec, I want it from the source, not from a forum or a generic CD. This manual gives you the exact tightening values for the 340-01, 341-01, and 341-02 models. Page 6.3? That’s where the axle tightening values for the 340-01 live – stuff like the planetary drive and wheel hub. You don’t guess. You look it up. That’s the difference between a job that stays fixed and a callback.

Maintenance: Fluids, Filters, and Bleeding the Fuel System

Section 3 walks you through the maintenance plan – fluids and lubricants, fuel filter cleaning, bleeding the fuel system. The manual specifies the exact viscosity for hydraulic oil, engine oil, axle oil. If you’ve ever put the wrong oil in a 280’s gearbox, you know how fast it gets expensive. They also cover the V-belt, air filter, and tyre care. Don’t skip the wheel change procedure – the torque sequence for lug nuts on a wheel loader is not the same as your pickup. Page 3.18 spells it out.

Engine and Fuel Injection System: Valve Clearance and Nozzle Specs

Chapter 4 goes deep into the engine – fuel injection system, injection nozzle specs, and valve tip clearance. The manual provides a table for engine trouble codes (section 4.11). If the engine won’t start and you’re chasing fuel supply, check section 4.9 for the fuel system overview. It shows the flow path from tank to injection pump. That’s the kind of detail that saves you from swapping a pump when it’s just a clogged filter. The heating circuit for the cab (engine–cab) is also diagrammed – useful if you’re in San Antonio and your heater’s dead.

Power Train: Variable Displacement Pump and Hydraulic Motor

Section 5 covers the variable displacement pump A10VG28DA and the hydraulic motor VM45EZ6. There are diagrams for the drive circuit, hydraulic oil circuit, and check/adjustment instructions. The model 340-01 (180) and 341-01/341-02 (280) have separate schematics. If you’re troubleshooting weak travel, you need to understand the pump’s displacement control – the manual dedicates section 5.10 to check and adjustment. No aftermarket manual gives you that level of detail on a pump that costs thousands to replace.

Axles: Tightening Values and Sealing Work

Chapter 6 is where most people mess up. Axle type labels, drain and fill plugs, screw connections, sealing work. The manual gives tightening values in Nm for the 340-01 (section 6.3) and for the 341-01/341-02 (section 6.8). It also covers the self-locking differential, planetary drive, and input shaft. If you’re replacing seals on the planetary carrier or axle tube, section 6.12 and 6.13 show the exact sealing procedure. Failure to follow that sequence leads to leaks that take a weekend to fix.

Brakes and Steering System: Adjustments and Track Setting

Brakes – section 7. Handbrake readjustment, brake pad replacement, cable pull basic setting. The steering system in chapter 8 includes hydraulic circuits for the 180 and 280, servostat pressure relief valve settings, steering ram sealing, and track setting. The track setting procedure (section 8.30 – 8.34) includes steps for checking, correcting, setting the steering limit, and synchronisation. If the loader doesn’t track straight, you follow that sequence – it’s all there. I’ve seen shops charge $500 for a steering alignment that’s really just a ram length adjustment from page 8.28.

Do I Need This Manual for Both the 180 and 280?

Yes. The manual covers models 340-01 (180), 341-01 (280), and 341-02 (280 with different drive lever). Differences are called out in each section – torque specs, diagrams, part numbers. The table of contents clearly separates the two drive lever variants (TD.5 vs TD.6). You get both in one PDF. That’s 238 pages for two machines.

Before you buy a $30 aftermarket PDF from some website, consider this: I’ve seen aftermarket manuals that skip the maintenance label explanation (section 3.2), omit the V-belt tension data, or give generic torque values that don’t match the axle hardware. This is the same document Kramer-Werke printed in 2007. Order number 1000104011 EN 06/07. If you want to check it against other factory literature, look at the Kramerallrad 4009 Parts Catalog – that parts catalog references the same torque specs from this service manual.

For other machines in the shop, you might need the White Outdoor LT-5 – 700 Series Rider Service Manual or the Maruti MB308 Service Manual Procedures and Repair – Section: Section 8A Wiring D. But for this wheel loader, get the factory manual. Also, if you’re not familiar with how a manual transmission works, reference Manual Transmission for basics, but don’t apply those general principles to a hydrostatic drive – the power train in this Kramerallrad is not a manual gearbox. The Manual Transmission article won’t help you with the A10VG28DA pump.

FAQ – Kramerallrad 180, 280 2007 Service Manual

Does this manual cover both the 180 and 280 wheel loaders?

Yes. One PDF covers the 340-01 (180) and the 341-01/341-02 (280). All sections separate specs where needed.

What about torque specs for the axles?

Section 6.3 gives tightening values for model 340-01. Section 6.8 covers the 341-01/341-02. They list in Nm – convert if you need ft-lb.

Is this the same manual that Kramer-Werke sold?

Yes. Factory PDF, order number 1000104011 EN, edition 2.1 from 06/07. 238 pages. No third-party rewrite.

I need to replace the steering ram seals. Where do I start?

Go to section 8.26 – sealing steering rams. It shows the disassembly and torque for the gland nut. Then section 8.28 for ram setting after reassembly. You will need a seal kit, a torque wrench, and the puller tool specified in the required tool list in TD.3.

Access the Factory Manual. I’ve been turning wrenches since before most of you were born. You want to work on this machine the right way, you get the factory documentation. That’s not a suggestion – that’s how you avoid a comebacker.
