Bomag BPR 25/45, BPR 100/80 2007 Training Manual – Factory Data You Can Trust

If you are a mechanic or shop owner who has ever tried to rebuild a Bomag reversible plate without the factory specs, you know the feeling. You guess a torque, it leaks. You miswire a sensor, the control unit locks you out. The Bomag BPR 25/45, BPR 100/80 2007 Training Manual is the document that stops that waste. This is not a reprint or a summary. It is the original OEM manual used in Bomag’s own service training program. 93 pages of factory data, wiring diagrams, and adjustment procedures. If you work on these plates, stop guessing.

Technische Daten und Einstellwerte – The Numbers That Matter

The manual opens with a section titled Technische Daten und Einstellwerte. That is German for technical data and adjustment values. This is where you find the real specs. Not generic values from a parts catalog, but factory-sourced numbers for the exciter system, hydraulic pressures, and bolt torques. If you are setting the exciter bearing preload or checking hydraulic system pressure, this table is your reference. Without it, you are relying on guesswork and hoping the threads hold.

Erregersystem and Verstellung – Exciter System Adjustment

The exciter system (Erregersystem) is the heart of the vibration. The manual covers the mechanical drive version (BPR) and the hydraulic version (BPH). It shows the construction of the exciter shaft, the eccentric weights, and the adjustment mechanism. There is a section on Handhebelverstellung (hand lever adjustment) and Tip Control – mechanical-hydraulic pump adjustment. You get exploded diagrams and step-by-step adjustment procedures. This is where most techs get it wrong. They skip the preload step and the machine vibrates unevenly. The mechanical drive on the BPR models operates differently from a Manual Transmission in a truck, but the principle of power transmission is similar. The manual tells you exactly how to set it.

Hydraulik / Elektrik BPH 80/65 – Wiring and Safety Interlocks

For the hydraulic drive models (BPH 80/65 and BPH 80/65 S), the manual includes dedicated hydraulic and electrical sections. It covers vibration switching, exciter shaft adjustment, and the vibration/start interlock (Anlassperre). The wiring diagrams are factory originals. You get the Stromlaufplan (wiring diagram) for the BPR 80/65 S and the 65/70D. These are not redrawn by a third party. They are the actual schematics from Bomag. If you are diagnosing a no-vibration or no-start condition, trace the circuit using these diagrams. For the hydraulic models, the drive is fluid-based, not a Manual Transmission at all.

LogikFunktionBPH – Control Logic Without the Headache

A separate section covers the logic functions of the BPH control system. It goes through each input: ignition on (S00), starter (S00 again), motor speed switch (S121), travel lever (S55, S75), vibration switch (S36), and the BMFSA display module. It even includes the remote control and cable operation (Funkfernsteuerung). If you have a machine that won’t vibrate or won’t start, this section tells you which switch does what and how to test it. No guessing.

Fehlercodes und Warnungen – Diagnostics Based on Real Fault Codes

The BLM Steuerung section lists all fault codes and warnings for the control unit. You get the code number, the symptom, and the corrective action. There is also a procedure to enter codenumbers, display stored faults, and clear them. If you are a technician who has spent hours chasing intermittent faults, having this code list saves you time. Page 2 of the manual (Vorwort) explains the importance of proper training and documentation – a reminder that this manual is meant for shop use.

Does this manual cover both the BPR 25/45 and BPR 100/80?

Yes. It covers the entire BPR Serie 4 including both models.

What language is the manual in?

The manual is in German. However, the diagrams, tables, and torque values are universal. If you need an English version, you will need a translator, but the technical content is clear.

Are the wiring diagrams complete?

Yes. The manual includes full wiring diagrams for BPR80/65S (Stromlaufplan 70118) and 65/70D (70117). These are original Bomag schematics, not redrawn. They show every wire, connector, and component. If you are troubleshooting an electrical issue, these diagrams are essential. Without them, you are working blind. I have seen techs cross-wire the remote control because they used a generic diagram. Don’t be that guy.

Can I use this for the BPH 80/65 S specifically?

The manual has a dedicated section for BPH 80/65 S including hydraulics, electrics, and logic functions. However, the primary focus is BPR. For a dedicated BPH manual, check related products below.
