Short Description

The 161-8573, also written as 1618573, is a bolt-on bucket heel-plate reference for selected Cat 966 and 972 loader bucket configurations. Offered as an aftermarket replacement, it is used for rear and bottom bucket wear-protection enquiries. The OEM reference identifies a rectangular profile with a notch. Confirm the bucket identification, plate outline, notch, mounting pattern, dimensions and required supply scope before ordering.

Full Description

The 161-8573, also written as 1618573, is a bolt-on bucket heel-plate reference associated with selected Cat 966 and 972 wheel loader bucket configurations. This listing is for an aftermarket replacement. The reference identifies the replacement application; the quoted item must be checked against the actual bucket and an approved specification before ordering. OEM names and numbers do not indicate genuine Caterpillar manufacture.

A heel plate is fitted to the rear and bottom wear area of a loader bucket. It provides a replaceable wear surface in an area exposed to contact with working material and the ground. Correct identification involves the mounting position, the surrounding bucket structure and the plate being replaced. Record the installed location when removing an old plate so the replacement enquiry clearly identifies the relevant bucket wear component.

The OEM reference describes a rectangular plate with a notch and bolt-on attachment. The complete outline and notch are important features to compare with the removed component and bucket mounting area. Matching overall length and thickness alone does not establish compatibility. Check the notch dimensions and position, hole layout, fastener seats and mating face against the required drawing.

Reference applications cover selected 966 and 972 loader buckets. Equipment within either model family can use different buckets or wear-protection arrangements. A machine model therefore helps narrow the search, while the bucket identification and existing part reference establish the configuration that needs checking. Include the machine PIN or serial number, bucket manufacturer and bucket identification number where available.

Loader bucket wear-protection enquiries may arise in abrasive material-handling operations. State the material being handled and describe the operating conditions when requesting a quotation. Photographs of the old plate and adjacent bucket structure can help explain uneven wear, damage or mounting concerns. The replacement specification should reflect the actual bucket arrangement and operating requirement.

For compatibility review, provide photographs of both faces, the notch, each mounting opening and the installed plate position. Supply measured length, width and thickness together with hole centre distances, offsets from defined edges, and notch dimensions. Use a drawing with clear measurement references where possible. An unworn sample or approved drawing is particularly useful when the removed plate is heavily worn or has been modified.

Distributors and importers should state the total order quantity and any repeat-purchase requirement. Repair businesses, contractors and mining maintenance teams should identify the number of plates required for each bucket and list any associated hardware separately. Agree the material requirements, any hardness requirements, dimensional acceptance criteria and inspection documents before order approval. Confirm the exact supply scope, packing requirements, destination and requested delivery date in the quotation. Product and packed weights require confirmation for shipping.

Compatible Machine Models

Selected reference applications are listed below. Compatibility requires the bucket configuration using 161-8573; the machine model alone does not confirm fitment. Check the machine PIN or serial number, bucket identification and actual mounting details before ordering.

Reference Part Numbers

161-8573 and 1618573 are common written forms of the same reference. No additional fully interchangeable heel-plate number is stated. Confirm any proposed alternative against the complete outline, notch, mounting pattern and bucket arrangement.

Applications

• Rear and bottom wear-protection replacement for the verified loader bucket configuration.

• Loader bucket maintenance in abrasive material-handling operations, subject to specification review.

• Replacement-part procurement for distributors and importers.

• Bucket repair enquiries from maintenance businesses, mines and construction contractors.
