Wacker Neuson BS 50, BS 500, BS 60, BS 600, BS 70 2004 Repair Manual

If you’re tearing down a Wacker BS 50 without the right torque values, you’re asking for a snapped bolt. This Wacker Neuson BS 50, BS 500, BS 60, BS 600, BS 70 2004 Repair Manual is the factory document. 106 pages.

Safety Information: Read This Before You Turn a Wrench

Section 1 goes beyond common sense. It covers operating safety with internal combustion engines, service safety, and repair safety specific to vibratory rammers. Wacker doesn’t mess around with liability. They list the exact personal protective equipment and procedures for fuel system work. If you skip this section, you’re working blind. I’ve had a rammer kick back on me once because I didn’t release the spring tension properly. The manual spells that out on page 9 under Service and Repair Safety. You also get warnings about hot surfaces, fuel vapor, and proper lifting techniques. This isn’t a suggestion – it’s the procedure that keeps your hands attached.

Technical Data for 17 Model Variants

You get separate technical data for every model: BS 50-2, BS 50-4, BS 500, BS 500S, BS 50-2i, BS 500-oi, BS 60/70-2, BS 60-4, BS 600/700, BS 600S, BS 60/70-2i, BS 600/700-oi, BS 600/700 High Altitude, BS 65-V, BS 650, DS 70, DS 720. Each variant has its own page with specifications like engine type, weight, impact rate, and lubrication capacity. The BS 60-4 and BS 500 have different air cleaner setups – the manual tells you which is which.

Torque Values and Threadlocking Compounds

Page 31 is where you live when rebuilding these rammers. The torque values table covers all critical fasteners. Don’t use a generic chart – Wacker specifies inch-pounds and foot-pounds for each bolt. Also listed are the threadlocking compounds (Loctite types) for the crank gear, connecting rod, and spring system. I’ve seen a loose connecting rod nut cause a catastrophic engine failure because someone used the wrong compound. This manual lists the exact Wacker part numbers for the recommended compounds.

Does This Manual Cover the Ramming System?

Absolutely. Section 5, starting at page 67, walks you through bellows replacement, ramming shoe removal and installation, spring system cover removal, spring inspection, and protective pipe service. The lubrication procedures differ between BS 500/600/700/650 and BS 50/60/70 models – the manual has separate subsections. If your rammer jumps erratically, check the troubleshooting section on page 97, but it usually comes down to worn bellows or a broken spring. Page 78 shows how to inspect the spring system properly.

Troubleshooting: Engine Hard to Start?

Section 8, from page 94, gives you a diagnostic flow for six common issues: engine hard to start, engine does not start, engine does not accelerate or runs poorly, engine overheats, rammer does not tamp, rammer jumps erratically. Each symptom has a list of probable causes and corrective actions. I used this section to diagnose a BS 70 that wouldn’t accelerate – turned out to be a clogged Tillotson carburetor. The manual’s carburetor section (page 50) shows the exact rebuild steps.

Source Authenticity: OEM Wacker Neuson Print

This is not an aftermarket compilation. It’s the original factory repair manual published by Wacker Corporation in 2004. The PDF is a direct scan from the official document, complete with the foreword, part number listings, and copyright notice. I’ve seen aftermarket manuals that transpose torque values or omit the high altitude variant specs. That’s dangerous. With this OEM manual, you get the exact data that Wacker engineers approved. The Manual Transmission knowledge doesn’t help here – this is specific to vibratory rammer drivetrains. For a broader context on construction equipment standards, you can reference the Automotive Industry Overview. If you need related manuals, check out Wacker Neuson Rammer Repair Manual BS 50 – DS 720 for the same series, Wacker Roller RD 27 Repair Manual – Section: Lubricating Articulated Steeri for roller service, and Wacker PT, PG, PD Pumps Repair Manual for pump repairs.

Does this manual cover the BS 700?

Yes, the BS 700 is included in the technical data and all applicable sections.

What torque spec for the crankshaft?

Page 31 lists torque values for all models. You need to look up your specific model variant because the BS 50 and BS 70 have different values.

How many pages?

106 pages of factory procedures – nothing wasted.

Is this a reprint from an aftermarket source?

This is the original OEM Wacker Neuson factory repair manual published in 2004, a direct scan of the official document. Aftermarket manuals often have errors in torque specs that can cause catastrophic failure. I’ve seen it happen with a Tillotson carburetor rebuild – the wrong throttle linkage adjustment led to a runaway engine. This manual gives you the exact Wacker procedure, including threadlocking compound specifications and the proper sequence for the spring system. Use that.

If you’re serious about keeping your Wacker rammer running without surprises, get the factory data. Stop relying on forum guesses or generic charts. Access the Factory Manual now and have the specs at your fingertips.
