3G3357 Bucket Adapter for J350 Loader Buckets – Aftermarket Replacement

The 3G3357 bucket adapter is offered as an aftermarket replacement for the J350 center bolt-on, two-strap adapter configuration. Also written as 3G-3357, this reference identifies the adapter between a loader bucket edge and a separate replaceable tooth. It should be distinguished from the tooth itself and from a one-piece unitooth. A correct purchase therefore starts with identifying which component needs replacement and which existing components will remain in service.

The adapter mounts at a center position along the bucket edge. Its bucket connection and tooth connection must both match the existing assembly. The two mounting holes are only one part of that check: buyers should also compare the strap opening, seating surfaces, hole locations and tooth interface. A matching family designation helps narrow the search, but does not establish complete interchangeability between different adapter part numbers.

For a replacement inquiry, provide the full machine model, serial number if available, bucket identification and old adapter markings. Bucket information matters because equipment may have been fitted with a replacement bucket or a modified cutting edge. Photographs should show the existing adapter from above, below and from the side, together with the bucket mounting area. Include close-ups of the tooth connection and any retaining components that need to be matched.

When submitting measurements, state the units and show the reference points on each photograph or drawing. Useful checks include the bucket edge thickness, mounting opening, hole center spacing and the geometry of the bolt seats. Record whether measurements came from a new sample, a worn component or an approved drawing. Heavy wear can change the measured profile, so an old part should not be treated as a complete manufacturing specification.

Typical purchasing situations include loader bucket maintenance, workshop repairs and distributor stock replenishment. For earthmoving, aggregate handling or other loading work, describe the actual material and operating conditions in the inquiry. These details help define the requested replacement; they do not establish that every tooth style, bucket arrangement or service condition is suitable for the same configuration.

Separate the required supply into the adapter, the tooth, adapter-to-bucket fasteners and tooth-retention components. Identify the references and quantities needed for each item. An adapter listing or a photograph does not establish that accessories are included. The quotation and order confirmation should specify the agreed components, packing arrangement, destination and delivery requirements.
