The Bomag 05712120 Shim is a genuine OEM component designed for Bomag BW 161 AC-2, BW 161 AD-2, BW 164 AC-2, BW 164 AD-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers, as well as BW 6 and BW 6 S walk-behind rollers. Sourced directly from Bomag, this shim carries the exact material grade, thickness tolerance, and dimensional spec of the original part it replaces. Correct shim selection is critical to maintaining proper bearing preload, gear mesh, and component alignment — and this genuine OEM part ensures you hit the spec the first time. Whether you are rebuilding a drum assembly, adjusting drivetrain clearance, or restoring a worn spacing stack, this shim drops in without guesswork.
Key Features
- OEM Thickness Tolerance — manufactured to Bomag's exact dimensional spec, ensuring the spacing and preload values your assembly depends on are met precisely
- Direct-Fit Installation — matches the original profile and material so it seats correctly in the same stack position as the factory shim, with no reworking of mating surfaces
- Broad Tandem and Walk-Behind Coverage — confirmed fit across BW 161 AC-2, BW 161 AD-2, BW 164 AC-2, BW 164 AD-2, BW 202 AD-2, BW 202 AHD-2 tandem rollers and BW 6, BW 6 S walk-behind rollers
- Protects Adjacent Components — a correctly fitted shim prevents excessive bearing wear, shaft movement, and gear mesh error that can cascade into costly drivetrain damage
- Genuine Bomag OEM Part — supplied under part number 05712120, traceable to Bomag's own catalog for confident procurement and parts documentation
A shim is a precision spacer used to control clearance, preload, and alignment between mating components such as bearings, gears, shafts, and housings. By setting the correct gap or compressive load in an assembly, a shim ensures that moving parts operate within their designed tolerances — reducing heat, vibration, and uneven wear. When a shim is missing, deformed, or worn to the wrong thickness, adjacent components can shift out of alignment, bearings can run with incorrect preload, and the resulting stress accelerates failure throughout the assembly. Using the correct OEM shim restores the assembly to its intended specification and protects the surrounding components from premature damage.
