The Bomag 05745490 Decompression Shaft is a genuine OEM component designed for the BW 75 H walk-behind light roller. Sourced directly from Bomag, this decompression shaft meets the exact specifications of the original part it replaces, ensuring correct function within the engine's starting system. This is the precise part number 05745490 referenced in Bomag's own service documentation for the BW 75 H.
Key Features
- Genuine OEM Engineering — machined to Bomag's exact dimensional and material specifications, ensuring the shaft engages and releases compression reliably during every engine start cycle
- Direct-Fit Replacement — designed to install into the BW 75 H engine assembly without alteration, matching original mounting points and shaft geometry
- Confirmed Fitment — verified for the BW 75 H walk-behind light roller; always cross-reference part number 05745490 against your machine's serial number before ordering
- Consistent Cold-Start Performance — a correctly functioning decompression shaft reduces engine resistance at startup, allowing the operator to pull-start the machine smoothly in all conditions
- Operational Safety — a worn or seized decompression shaft can make the engine difficult or unsafe to start; replacing it with the correct OEM part restores safe, controlled engine engagement
The decompression shaft is a small but critical engine component that temporarily vents cylinder pressure during the pull-start sequence, making it easier for the operator to turn the engine over by hand. Without it functioning correctly, the engine can become extremely difficult to start or may kick back against the starter cord, creating a risk of injury. When this shaft wears, bends, or seizes, starting the machine becomes a struggle — replacing it promptly keeps the BW 75 H roller operating as intended and the operator safe.
