Description
Overview:
The Bucket Packing Shim is a flat, ring-shaped spacer designed for excavator and digger bucket joints. Built from durable metal, it sits within the pin stack or between mating faces to take up side play and keep the bucket aligned under load. With an internal diameter of 80 mm (3.15 inches) and a thickness of 3 mm (0.12 inches), it suits assemblies built around an 80 mm pin or boss and allows fine adjustment by adding or removing shims. By reducing wobble and sideways movement, it improves control, grading accuracy, and helps limit knock and wear on pins and bushes during everyday digging, trenching, and loading. Simple to fit and replace, it is a practical component for routine maintenance in workshops and on site.
Key Features:
- 80 mm internal diameter (3.15 inches) for 80 mm pin/boss interfaces
- 3 mm thickness (0.12 inches) for precise adjustment and easy stacking
- Flat washer-style form for quick fitting between bucket, linkage, or dipper-end faces
- Helps reduce bucket wobble and sideways movement for smoother operation
- Assists in maintaining accurate bucket control and breakout alignment
- Minimises impact and wear on pins, bushes, and linkages by keeping loads even
- Durable metal construction for reliable performance in tough site conditions
- Easy to install and remove with basic hand tools during service work
- Suitable for workshop rebuilds and on-site repairs across many excavator makes (size-dependent)
- Cost-effective way to restore a tight pin stack without major component replacement
- Identified by MPN 300 048 for straightforward reordering
Typical Applications:
Taking up side clearance on bucket pin stacks, between bucket ears and the dipper or quick coupler; reducing lateral movement after wear develops; setting end-float during pin and bush replacement; pre-hire or scheduled services to improve machine feel; general construction, utilities, demolition, and landscaping tasks where accurate bucket positioning is required.
