Chain Wheel Sprocket 4812027420 Feeding Shaft Drive for BF980C SD2500 SD2530 SD2550 Pavers

Chain Wheel Sprocket 4812027420 is the feeding shaft drive sprocket used on BF980C, SD2500, SD2530 and SD2550 asphalt pavers. It is a direct replacement component for the paver conveyor feeding shaft, supplied as 100% new stock so the machine can return to work without re-machining or shimming.

Buyers normally trace this part through the OE reference number carried on the old sprocket or the parts manual. The reference 4812027420 is the primary matching key, and the four machine models below share the same feeding shaft mounting pattern, so one stock item covers the whole fleet.

• One part number, four machine models. The 4812027420 sprocket fits BF980C, SD2500, SD2530 and SD2550, which lets contractors and rental fleets keep a single line of stock instead of four separate part numbers.
• Forged alloy steel body. The blank is forged rather than cast, giving a denser grain structure that resists tooth deformation under the shock loads of an asphalt paver feeding shaft.
• Precision machined tooth profile. The tooth form is cut to match the original chain pitch, reducing chain wear, noise and the risk of chain jumping during continuous paving.
• Keyed shaft location. The hub is machined with a keyway and flange bolt pattern for positive location on the drive shaft, keeping the sprocket concentric after installation.
• 15 kg per piece, ready to install. Supplied as a complete chain wheel with no additional bushing kit needed, so the replacement is a direct bolt-on job on site.
