How do I replace a coupling head?

Identify the correct coupling head in terms of total weight, diameter drawtube, hole pattern and c-c measurement. (vertical/crossed/horizontal)

How do I find the right coupling head?

Perform the following steps during assembly:

  1. If you are using a universal coupling head, which fits several diameters of drawtube, choose the right adapter. The outer diameter of the drawtube must be the same as the inner diameter of the adapter.
  2. Start by pushing together the coupling damper so that the sleeve is in the same position as the rear hole of the drawtube.
  3. Take the rear bolt and press this through the hole on the coupling head, drawtube and sleeve on the coupling damper.
  4. Press in the front bolt.
  5. Do not forget to perform a functional check of the coupling head.
