The Bomag 04050117 Shim is a genuine OEM component designed for a wide range of Bomag compaction equipment, including the BMP 851 trench compactor, BW 138 AC-5 and BW 138 AD-5 tandem rollers, BW 135 AD-5 tandem rollers, BPR 30/38 and BPR 30/38 D reversible vibratory plates, BP 18/53 and BP 20/53 vibratory plates, and BW 71 E, BW 75 S, and BW 90 S walk-behind rollers. Sourced directly from Bomag, this shim meets the exact material and dimensional tolerances required for proper assembly and alignment across each of these platforms. Installing the correct OEM shim ensures components seat and preload as engineered, protecting the integrity of the surrounding assembly.
Key Features
- OEM Dimensional Precision — manufactured to Bomag's exact thickness and material spec, ensuring the shim delivers the correct spacing and preload for its application rather than an approximate fit
- Drop-In Replacement — matches the original profile so it installs directly within the existing assembly without grinding, shimming further, or modifying adjacent components
- Broad Fitment Coverage — confirmed for the BMP 851 trench compactor, BW 138 AC-5, BW 138 AD-5, and BW 135 AD-5 tandem rollers, BPR 30/38 and BPR 30/38 D reversible vibratory plates, BP 18/53 and BP 20/53 vibratory plates, and BW 71 E, BW 75 S, and BW 90 S walk-behind rollers
- Assembly Integrity Protected — correct shim thickness prevents bearing preload errors, component misalignment, and accelerated wear in mating parts that depend on accurate spacing
- Genuine Bomag OEM Part — part number 04050117 is an authentic Bomag component, eliminating the guesswork of cross-referencing aftermarket alternatives for a part where dimensional accuracy is critical
A shim is a precisely dimensioned spacer used to set the correct clearance or preload between two assembled components — such as bearings, housings, shafts, or drive elements. Even a small deviation from the specified thickness can cause uneven load distribution, premature wear, or component failure in the assemblies it supports. When a shim wears down, deforms, or is replaced with an incorrectly sized piece, the resulting misalignment puts stress on surrounding parts and can lead to costly secondary damage. Using the correct OEM shim, like this Bomag 04050117, ensures the assembly is restored to its original specification and performs as intended under compaction loads.
