The Bomag 05740979 Spacer Disk is a genuine OEM component designed for Bomag tandem rollers across the BW 100, BW 115, BW 120, BW 125, and BW 131 series, including the BW 100 AD-4, BW 100 AC-4, BW 120 AD-5, BW 120 AC-5, BW 125 AD-4, BW 131 AD-5, and additional variants. Sourced directly from Bomag, this spacer disk meets the same specifications as the part originally installed at the factory. Compatible models span multiple generations — from -3 and -4 through -5 series tandem rollers — making this a versatile OEM solution for fleets running multiple machine configurations. When fitment accuracy matters, ordering by part number 05740979 ensures you receive the correct component for your machine.
Key Features
- Genuine OEM Precision — manufactured to exact Bomag tolerances, ensuring the spacer disk maintains correct axial clearance and alignment within the drivetrain or drum assembly.
- Direct OEM Replacement — this spacer disk installs in place of the original without modification, preserving the designed spacing and load distribution of the assembly.
- Broad Tandem Roller Coverage — fits BW 100, BW 115, BW 120, BW 125, and BW 131 tandem rollers across -3, -4, and -5 generation variants, including AC, AD, SL, SLC, ACW, and CC configurations.
- Protects Adjacent Components — a correctly fitted spacer disk prevents unwanted lateral movement and bearing wear, protecting costlier surrounding components from premature failure.
- Verified by Part Number — ordering Bomag part number 05740979 confirms you are receiving the correct OEM disk spec'd for your tandem roller, eliminating guesswork during service.
A spacer disk is a precision-machined component used to establish and maintain correct spacing between rotating or stationary parts within an assembly — such as a drum drive, bearing housing, or gearbox. It ensures that adjacent components are held at the designed distance from one another, preventing axial play, misalignment, and uneven load distribution. When a spacer disk wears down or is damaged, it can allow unwanted movement that accelerates bearing and seal wear, leading to more extensive drivetrain repairs if left unaddressed.
