1U1857 Bolt-On Bucket Tooth for Cat 924F and 928G Loaders

Product Overview and Full Description

The 1U1857 bucket tooth is a bolt-on, one-piece wear component for a matching bucket lip. The forward tooth section and rear mounting straps form a single body, commonly described as a unitooth or monoblock tooth. The photographed YASSIAN sample has a yellow finish, two mounting holes and an open space between the upper and lower straps. It is offered as an aftermarket replacement using 1U1857 and 1U-1857 as identification references.

This tooth is intended for compatible center positions along the front of a bucket. Its mounting section fits around the matching lip and is secured with the correct bolt arrangement. The integrated design does not require a separate tooth adapter for this mounting configuration. The complete mounting interface must match the bucket, including the lip thickness, hole spacing, hole shape and seating surfaces. A similar outline alone is insufficient to establish interchangeability.

The reference application is general loading and earthmoving with a correctly equipped bucket. Buyers should describe the material handled, working conditions and existing wear pattern when requesting a quotation. For rock impact, demolition or other demanding duties, the tooth selection needs a separate application review. The relevant question is whether the proposed part matches both the attachment and the intended work, rather than whether its number appears in a broad list of machinery parts.
