The Bomag 05728478 Ring Gear is a genuine OEM component designed for BPR 40/45 D, BPR 40/45 D-2, and BPR 40/45 D-3 reversible vibratory plates. Sourced directly from Bomag, this ring gear is manufactured to the exact tolerances required for proper drive engagement and long service life on your machine. This part is a direct drop-in replacement for the BPR 40/45 D series, ensuring correct mesh geometry and load distribution from the moment it is installed.
Key Features
- Genuine OEM Drive Engagement Accuracy — manufactured to Bomag's exact tooth profile and hardness specifications, ensuring correct gear mesh and load transfer in the drivetrain
- Direct Replacement for the BPR 40/45 D Series — engineered to install in place of the original ring gear with no additional machining or fitment adjustments
- Confirmed Fitment — compatible with BPR 40/45 D, BPR 40/45 D-2, and BPR 40/45 D-3 reversible vibratory plates
- Drivetrain Integrity Restored — a worn or damaged ring gear causes erratic plate travel, loss of propulsion, and accelerated wear on mating components; replacing it promptly keeps the compaction system running as intended
- Verified Part Number — ordering by part number 05728478 confirms you are receiving the correct Bomag ring gear for your specific machine variant
The ring gear is a core component in the reversible vibratory plate's drive system, transmitting rotational force from the engine or motor to the exciter or travel mechanism. It works in mesh with a pinion or drive gear, and the precision of its tooth form directly determines how smoothly and efficiently power is transferred. When a ring gear wears, chips, or cracks, the result is rough or intermittent plate movement, unusual drivetrain noise, and eventually a complete loss of forward or reverse travel — making timely replacement essential to keeping the compactor productive on site.
