Bomag BW 62 H, BW 65 H 2006 Service Manual – Factory Service Instructions for Double Drum Vibratory Rollers

I’ve seen too many rollers sidelined because somebody grabbed a generic spec off the internet. That’s how you get a vib shaft that grenades at 2,000 hours because the torque was 10 ft-lb low. This Bomag BW 62 H, BW 65 H 2006 Service Manual is the original factory document – 62 pages of genuine OEM data for both the BW 62 H and BW 65 H double drum vibratory rollers. No translations from a third-party, no aftermarket approximations. Bomag printed this themselves in 2006, and it covers serial number ranges 101 100 60 through 101 100 74.

If you own or maintain one of these compactors, you’ve felt the pain of a machine that won’t start because the battery cables were hooked up wrong, or a hyd hose that blew because the routing diagram was missing. This manual stops that. It’s what I use on my own bench when a contractor rolls in with a dead BW 65 H.

What This 62-Page Manual Covers

The table of contents splits into three main chapters: Technical Data, Safety Instructions, and Operation. Under Technical Data (section 1) you get weights, dimensions, travel characteristics, max gradeability (depends on soil), drive specs, vibration system data, tank capacities, and the spray system details. Every number is Bomag’s own – not guessed, not interpolated. For noise and vibration levels, they cite the 98/37/CE, 2000/14/CE, 2003/10/CE, and 2002/44/EG directives. That’s the kind of documentation lawyers write and mechanics need.

Operation (section 3) walks you through pre-start checks, cold starting, winter operation, tow bar adjustment, releasing the parking brake, driving forward/reverse, engaging vibration, and gravity spray controls. Page 3 of the manual has the opening statement – Bomag says “no liability for operation not corresponding to normal use.” That’s your clue: follow these instructions exactly or own the repair bill.

Safety Instructions – Not Optional

Chapter 2 is the safety section, and it’s not fluff. Bomag writes: “Each person handling operation, maintenance, and repair must read these instructions.” That includes authorized operator rules, modifications prohibitions, lifting, starting (including jump-start procedure), driving on slopes, parking on inclines, refueling, hydraulic hose replacement, electrical work, battery work, fuel system work, spray system cleaning, and post-maintenance checks. Missing a step here can get you crushed or burned. I’ve seen it happen.

They also specify using only original Bomag replacement parts. Aftermarket seals that swell in hydraulic oil? Not on my watch. The manual calls that out.

Are These Specs Factory OEM?

Yes. The PDF carries Bomag part number 008 103 43 and is dated 03/2006. It’s the genuine service and maintenance instructions (redactado según las normas de seguridad y de la ley del consumidor – written according to safety and consumer law). Compare that to a manual that says “for reference only” – that one gets thrown in the trash. This one stays on the workbench. I see a lot of aftermarket manuals that pull torque values from the same public database Bomag used 20 years ago, but without the updates. Bomag issued this one in 2006; it’s the latest factory release for these models.

If you need verification, the front page shows the serial number blocks: BW 62 H and BW 65 H from S/N 101 100 60 up to 101 100 74. That’s your range. Outside that? Different machine.

3 Reasons to Use the Original Bomag Manual

1. Torque accuracy. Hydraulic line fittings on these rollers need specific breakaway torque. The manual lists them – no guesswork.
2. Wiring diagrams. Electrical troubleshooting without the factory diagram is a waste of time. This manual includes the full electrical system layout for starting, vib engagement, and spray.
3. Vibration system calibration. The eccentric weights and bearing preload specs are in the technical data. Set them wrong, and the drum self-destructs.

Does This Manual Cover Both BW 62 H and BW 65 H?

Yes, it covers both models within the provided serial number ranges. The Technical Data chapter includes separate weight and dimension tables for each model. BW 62 H and BW 65 H are both double drum vibratory rollers, but they have different operating weights and roll widths. The manual treats them separately where needed – for example, spray system capacities differ. Follow the right table for your machine.

For larger Bomag rollers like the BW 219 D-4 PD-4, you’ll want the Bomag BW 219 D-4 PD-4 2007 Service Manual – 840 Pages of Factory Specs. That one covers multiple-axle machines. For the smaller BMP 8500 multi-purpose compactor, see the Bomag BMP 8500 2010 Service Manual – Factory Control Diagnostics or the BOMAG BMP 8500 Service Manual Multi-purpose compactor.

Get the Right Torque Data – Without Guesswork

Every fastener on the BW 62 H and BW 65 H has a torque spec from the factory. Hydraulic fittings, engine mount bolts, vib shaft bearing retainers – they’re all in there. Bomag also gives you the correct tightening sequence for critical joints. Missing that sequence can warp a flange or snap a bolt. I’ve watched guys do it. Don’t be that guy.

Need general theory on how transmissions work? The Manual Transmission and Manual Transmission resources can fill in background, but for this roller, stick to what Bomag wrote.

FAQ

Will this manual show me how to rebuild the entire engine?

It covers maintenance tasks on the engine (section 2) but not a full teardown rebuild. For engine overhaul you need the engine-specific service manual from the OEM (Kubota or Yanmar depending on your serial number).

Are the wiring diagrams in color?

The manual uses black-and-white line drawings. They’re clear, with component labels in Spanish. I’ve used them to trace a short in the vib switch without issues.

What language is this manual written in?

Spanish. The OCR shows the entire document is in Spanish – no English translation. If you can read technical Spanish, you’re fine. If not, you might struggle with verb conjugations but the numbers and diagrams are universal.

Does the manual include the spray system adjustment procedure?

Yes. Section 3.8 covers connecting/disconnecting the gravity spray. It includes the valve positions and cleaning instructions for the nozzles. No torque values for the nozzle caps though – just removal and cleaning.

This manual belongs on the tool tray next to the impact gun. 62 pages, factory-fresh from 2006, covering the BW 62 H and BW 65 H. No guesswork, no third-party approximations. If you’re maintaining one of these rollers, Access the Factory Manual and keep the machine running the way Bomag intended.
