  Q: When should the distributor be removed and what are the steps involved in the process on Volkswagen Transporter?

  A:

  The distributor should be removed only if indications suggest it needs renewal or overhaul. Begin by taking off the distributor cap and disconnecting the LT wire from the coil terminal, then detach the pipes connected to the vacuum advance unit. The distributor is secured by a clamp gripping the lower circular part of the body, which is held to the crankcase by a single bolt; removing this bolt allows the distributor and clamp to be lifted out together. It is important to note that if the bolt securing the clamp to the distributor is loosened and the positions of the distributor and clamp are altered, the static ignition timing will be affected. The lower end of the distributor drive shaft features a driving dog with offset engagement lugs that fit into corresponding slots, preventing the shaft from being set 180° out of position during reinstallation. Additionally, renewing the rubber 'O' ring in the annular exterior groove of the body is advisable, as this seal prevents oil from leaking up the outside. Replacing the distributor involves reversing the removal process, ensuring that the offset drive shaft dogs are correctly aligned for proper engagement and full seating of the body.
