Pin Shim 50mm JCB 82x51x1mm - 823/00220

Technical Specification and Compatibility

Shim washer with part number 823/00220 from the GX-AFTER offer. It is a steel ring with dimensions 82 x 51 x 1.0 mm, designed to eliminate axial play on 50 mm diameter pins. Commonly used in the kinematic systems of JCB machines (JS excavators, backhoe loaders, loaders), in places such as the bucket-to-arm connection, kingpost, or cylinders.

Part Number: 823/00220
Component Type: Shim / Spacer
Inner Diameter: 51 mm (for 50 mm pin)
Outer Diameter: 82 mm
Thickness: 1.0 mm
Material: Hardened Steel
Manufacturer: GX-AFTER

GX-AFTER precision shims are essential for proper attachment installation. Thanks to the use of high-grade steel, they are resistant to abrasion and crushing, which allows for long-term maintenance of the rigidity of pin connections.

Features of GX-AFTER 823/00220 Shim

Play Elimination: Allows precise removal of side play between the bucket ear and the arm, which prevents knocking and accelerated pin wear.
Seal Protection: Correctly selected spacer prevents crushing of dust seals (O-rings or lip seals) by working elements.
Pressure Resistance: Steel of appropriate hardness does not undergo plastic deformation under the influence of huge forces occurring in the excavator system.
Versatility: Standard dimension for 50mm pins makes the shim fit many JCB machine models and other manufacturers.

Application in JCB machinery

Category Application
Crawler Excavators JCB JS 130, JS 145, JS 160, JS 180, JS 200, JS 220 (Bucket pins, link - where 50mm dia exists)
Backhoe Loaders 3CX, 4CX (Nodes with increased pin diameter, e.g., rear arm in some Heavy Duty versions)
Loaders Loadall telehandlers (Cylinder pins, frames - verify by dimension)

The shim fits any 50 mm diameter pin where axial play reduction is required.

Related Parts and Hardware

The shim is a mounting element for 50mm pins. When regenerating the connection, it is worth also replacing sliding bushings and dust seals (O-rings) to ensure long node operation.

⚠️ Operational Warning

Leaving too much side play on the bucket pin causes impacts during operation ("clapping"), which drastically accelerates the wear of bushings and sockets in the arm. Using shims is a cheap way to avoid expensive arm re-sleeving.

Part Role in the Machine and Failure Diagnostics

Shim 823/00220 fills the space between the attachment ear and the machine arm.

  • › Noise during operation (axial play, lack of shims).
  • › Grease leak (shim does not press the seal).
  • › Rapid bush wear (uneven force distribution).
  • › Arm surface wear (metal-on-metal friction without spacer).

🔧 Expert Guide: Key Installation Tips

  1. Thickness Selection: Always have shims of different thicknesses handy (e.g., 1mm, 2mm, 3mm). This allows for a perfect "tight" fit of the pin, leaving minimal play for lubrication.
  2. Order: Shims are usually installed between the arm ear and the bucket ear, often protecting rubber dust seals with them.
  3. Greasing: After installing and eliminating play, grease the pin abundantly. Grease must flow out through the gaps, creating a protective barrier.

Technical FAQ and Trivia

What pin does it fit?

The shim has an internal diameter of 51 mm, so it is ideal for pins with a nominal diameter of 50 mm. This ensures 1 mm of mounting clearance.

What is the thickness?

This specific model is 1.0 mm thick. It serves to precisely eliminate small clearances. Other thicknesses are also available for larger adjustments.

Trivia about play

Did you know that an axial play on a pin of just 2 mm can cause a knocking sound audible within a radius of several dozen meters? This is because the metal structure of the excavator arm acts like a resonance box, amplifying every impact.
