WHY ?
Any assembly which requires free movement & noise reduction demands a proper clearance amongst its parts. Hence shims and spacers come into the picture to achieve this requirement.
HOW?
To maintain the proper clearance, various parts are individually measured for particular dimension & based on clearance formula, the Shim or Spacer size is derived. After defining the Shim or Spacer size, the proper Shim or Spacer is selected. An independent station verifies whether the selected shim dimension matches the calculated dimension. After selection of correct Shim or Spacer, it is put in that particular assembly & the performance of the assembly is checked.
