The Bomag 05702539 Diesel Engine is a genuine OEM replacement built for BW 135 AD, BW 138 AD, BW 138 AC, and BW 138-AD tandem rollers. Sourced directly from Bomag, this engine delivers an exact drop-in match to the original specification — no guesswork, no fitment concerns. It is confirmed compatible across the BW 138-series tandem roller lineup, making it the straightforward choice when a full engine replacement is needed.
Key Features
- Genuine OEM Power Output — matched to the original fuel delivery, displacement, and torque output spec for these tandem rollers, so the machine performs exactly as designed off the assembly line
- Direct Engine Swap — engineered to align with existing mounts, connections, and ancillary fittings on BW 135 AD and BW 138-series tandem rollers for a clean installation
- Confirmed Tandem Roller Fitment — fits BW 135 AD, BW 138 AD, BW 138 AC, and BW 138-AD tandem rollers, covering the full spread of this Bomag compaction series
- Full Propulsion and Compaction Restored — a correctly functioning diesel engine keeps drum drive, vibration systems, and hydraulics operating at rated capacity; a failed engine brings the entire machine to a stop
- Genuine Bomag Part Number 05702539 — verify against your machine's parts manual or serial plate to confirm the correct replacement before ordering
The diesel engine is the core power source for the tandem roller, driving both the propulsion system and the hydraulic circuits that power the vibratory drums and steering. Without a properly functioning engine, the roller cannot generate the drum frequency or travel force needed to compact asphalt to specification. When an engine shows signs of failure — excessive smoke, loss of power, or inability to start — replacing it with a genuine OEM unit restores the machine to its original rated output and keeps the compaction process on schedule.
