Shims for your Mini Digger & Excavator

Excavator shims are essential to securely fit your quick hitch, buckets and attachments to your excavator. In this guide, we'll delve into the intricacies of excavator shims, discussing what they are, when to use them, and how to use them effectively.

What are Excavator Shims?

Excavator shims , often referred to simply as shims or shim washers, are thin pieces of mild steel, designed to fill gaps between excavator components to avoid slack, movement and premature wear. Shims are most commonly used to secure buckets, attachments and quick hitches to your mini digger or excavator dipper end. If your excavator attachments do not fit snuggly to your dipper end, the slack will allow the attachment hangers or quick coupler to move while in use, leading to wear of both components over time. A loose attachment or quick hitch can be difficult to control when operating and could even lead to injury or damage to other equipment.

When should you use Excavator Shims?

Knowing when to use shims is crucial for ensuring proper fitment and avoiding unnecessary where to your excavator and excavator attachments. Here are some common scenarios where shims are essential:

Alignment Correction - During mounting or maintenance, components may not fit perfectly due to manufacturing tolerances or wear and tear. Shims help adjust these alignments by filling in any spaces between the bucket hanger and the end of the excavator, preventing premature wear and optimising your performance while operating.

Wear Compensation - Over time, parts of the excavator may wear unevenly, leading to movement in your hitch or attachment. Shims can be inserted between the bucket hangers and the dipper end to compensate for this wear, extending the lifespan of your equipment and returning your operations to optimal performance.

How To Use Excavator Shims

Step 1: Locate the Issue & Prepare the Surface

Determine where misalignment or gaps exist. Ensure that the surfaces where the shims will be placed are clean and free of debris. This promotes better contact and prevents accelerated wear to the shim and components.

Step 2: Select the Correct Shim Size

Determine the appropriate shim sizes to close the gap by inserting different size shims until snug. When inserting shims, start with the thinnest shims and add more as necessary until the gap is filled and the components are secure.

Step 3: Secure the Components

Once alignment is confirmed, secure the components in place using appropriate fasteners or locking mechanisms.

Step 4: Monitor and Adjust

Periodically check your digger for signs of movement or wear and make adjustments to the shims as needed to maintain a snug fit and optimal performance.
