Parts Order

Part order policy:

  • Although parts are available for purchase by private parties, the purchase and installation of parts by an unauthorized repair shop or person will void the Manufacturer’s warranty and The Sigma Corporation of America will not be held responsible.
  • Certain parts will not be available for sale due to the complex level of replacement and special tools required for proper installation and adjustment.
  • The Sigma Corporation of America or its Authorized Parts Distributors, CRIS and Bigston Corp., will not accept the return or exchange of any part that was removed from its original packaging.
  • Service Manuals, Diagrams and Parts break downs are not available for public distribution.
  • Parts availability is subject to the specific product service life.
