The Bomag 05744161 Decompression Shaft is a genuine OEM component designed for a range of Bomag compaction equipment, including the BT 80 D tamper, BW 75 H walk-behind roller, and BPR 40/45 D, BPR 40/45 D-2, BPR 40/45 D-3, BPR 50/52 D, BPR 50/52 D-2, and BPR 50/52 D-3 reversible vibratory plates. Sourced directly from Bomag, this shaft matches the original manufacturer's specifications — ensuring a correct, confident installation every time. When you order part number 05744161 from DHS Equipment, you're getting the same component that left the factory floor, with no guesswork on fitment.
Key Features
- Genuine OEM Precision — Manufactured to Bomag's exact tolerances for the decompression shaft, ensuring the component seats and operates correctly within the engine's starting mechanism.
- Direct OEM Replacement — Engineered to swap in place of the original shaft with no reworking or adaptation needed across all covered models.
- Broad Fitment Coverage — Fits the BT 80 D tamper, BW 75 H walk-behind roller, and the BPR 40/45 D, BPR 40/45 D-2, BPR 40/45 D-3, BPR 50/52 D, BPR 50/52 D-2, and BPR 50/52 D-3 reversible vibratory plates.
- Dependable Cold-Start Performance — A properly functioning decompression shaft allows the engine to turn over freely on the pull stroke, making reliable starting possible even in demanding field conditions.
- Fuel System and Starting Safety — Correct decompression shaft function is essential to safe, controlled engine starts; a worn or damaged shaft can cause hard starting or uncontrolled compression events during pull-start operation.
The decompression shaft is a critical part of the engine's manual starting system. It briefly opens an exhaust or decompression valve during the pull-start stroke, releasing cylinder pressure so the operator can bring the engine up to the speed needed for ignition — without fighting full compression on every pull. When this shaft wears, cracks, or fails to actuate correctly, the engine becomes extremely difficult or impossible to start by hand, and continued forced attempts can strain the recoil starter assembly. Replacing a failed decompression shaft with a genuine Bomag part, such as part number 05744161, restores proper starting behavior and protects the broader starting system from secondary wear.
