Bomag 06421246 Star Knob

The Bomag 06421246 Star Knob is a genuine OEM replacement component designed for a wide range of Bomag pavers, single drum rollers, tandem rollers, pneumatic tyred rollers, cold milling machines, soil compactors, refuse/landfill compactors, and recycler/stabilizers. Sourced directly from Bomag, this star knob matches the exact specifications of the original part, ensuring a correct, consistent fit across every compatible machine. This part covers an extensive lineup including BF-series pavers, BW-series rollers, BM-series cold milling machines, BC-series compactors, and MPH/RS-series recyclers and stabilizers. When the original knob becomes worn, cracked, or lost, this genuine OEM replacement restores full operator control without the guesswork of sourcing an imprecise substitute.

Key Features

• Genuine OEM Construction — manufactured to Bomag's original material and dimensional standards, delivering the same grip profile, thread engagement, and surface finish as the part it replaces
• Direct-Fit Replacement — threads and dimensions match the original mounting point exactly, so this star knob installs without reworking the mating hardware or surrounding assembly
• Broad Machine Coverage — fits a wide range of Bomag equipment including BF 300, BF 600, BF 700, BF 800, and BF 900 pavers; BW 177, BW 213, BW 216, BW 219, and BW 226 single drum rollers; BW 141, BW 154, BW 174, BW 184, and BW 202 tandem rollers; BM 500/15 and BM 600/15 cold milling machines; BC 462 EB soil compactors; BC 462 RB, BC 472 RB, and BC 472 RS refuse/landfill compactors; MPH 122-2, MPH 125, MPH 600, and RS 650 recyclers/stabilizers; and the BW 28 RH pneumatic tyred roller
• Sustained Operator Control — a star knob provides the hand-friendly grip surface used to adjust or lock machine settings; a worn or missing knob makes precise adjustments difficult, slowing operation and increasing operator fatigue
• Long-Term Durability — built from the same materials specified for the original part, resisting the vibration, dust, and repeated handling typical in active compaction and paving environments

A star knob is a small but important manual control component found at various adjustment and locking points on Bomag equipment. Its distinctive multi-lobe grip allows operators to tighten, loosen, or position a setting by hand — without tools — making it central to quick, accurate machine adjustments during operation. When a star knob cracks, strips, or goes missing, the adjustment point it controls becomes difficult or impossible to set correctly, which can affect machine setup accuracy and slow down the crew on the job.
