JCB Shim Washer 60x90x4mm
Steel shim washer (adjustment washer). A structural element of the kinematic system for working attachments and suspension in JCB machinery. Designed for the precise elimination of axial play on pins connecting arms, booms, and chassis components.
Technical features:
- Material: Made of steel with high resistance to surface pressure and abrasion. Provides dimensional stability under heavy static and dynamic loads.
- Function: Installing the shim allows for the elimination of lateral (axial) play, which protects pin seats from "hammering out" and prevents improper force distribution in the machine's joints.

Technical Advice: Before installing the shim, thoroughly clean the contact surface between the boom lug and the pin housing. Axial play left exceeding 1 mm drastically accelerates the wear of pin seals and can lead to fatigue cracking of the arm welds. During adjustment, aim for minimum resistance during axial movement, which guarantees correct grease distribution throughout the joint.
