Bomag 05740178 Injection Pump

The Bomag 05740178 Injection Pump is a genuine OEM fuel system component designed for Bomag BW 80, BW 90, and BW 100 series tandem rollers. Sourced directly from Bomag, this injection pump meets the exact specifications of the original unit it replaces, ensuring correct fuel delivery performance across the full range of compatible machines. This pump fits an extensive lineup including the BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 80 ADS, BW 90 AC-2, BW 100 SCC-5, BW 80 AD-5, BW 90 AD-5, BW 100 ADM-5, BW 90 SC-5, BW 100 SC-5, BW 100 ACM-5, BW 90 AC-5, BW 90 SL-5, BW 90 SL-5 CC, and BW 100 SLM-5 tandem rollers. When the original pump fails, replacing it with genuine OEM part number 05740178 restores proper engine fuel metering and keeps your tandem roller running at full operating capacity.

Key Features

• OEM Fuel Metering Accuracy — manufactured to Bomag's original injection timing and delivery volume specifications, ensuring the engine receives precisely metered fuel at every load point
• Direct-Fit Replacement — matches the original mounting configuration, port sizing, and drive interface of the pump it replaces, so installation follows the standard service procedure without modification
• Broad Tandem Roller Coverage — confirmed fit across the BW 80, BW 90, and BW 100 tandem roller families, including AD-2, AD-5, AC-2, AC-5, SC-5, SCC-5, SL-5, SL-5 CC, ADM-2, ADM-5, ACM-5, and ADS variants
• Consistent Engine Output — a correctly functioning injection pump maintains steady power delivery and smooth compaction passes; a worn or failing pump causes hard starting, loss of power, and uneven engine response
• Fuel System Integrity — as a genuine OEM component, this injection pump is built to handle the fuel pressures and duty cycles specific to Bomag tandem roller engines, supporting long-term fuel system reliability

The injection pump is the heart of the diesel fuel system, drawing fuel from the tank and delivering it to each injector at precisely controlled pressure and timing. Correct injection timing is critical to engine efficiency — too early or too late, and combustion suffers, robbing the roller of power and increasing fuel consumption. When an injection pump wears or fails, operators typically notice hard starts, rough idling, black exhaust smoke, or a marked drop in compaction performance; replacing it promptly with a correctly specified unit restores full engine function and protects downstream fuel system components from the effects of poor fuel delivery.
