Condensectomy - overview

 

The aims of a 'condensectomy' are:

  • to take the condenser that is buried in the armature out of circuit, and possibly remove it completely;

  • to maintain the connection of the 'earth' side of the low-tension winding to the body of the armature; and

  • to maintain the connection of the 'live' side of the LT winding to the live contact breaker point.

Then, when an EasyCap is fitted to the contact breaker assembly, the whole magneto can function as intended, without the old condenser interfering with the operation.

A number of people have mentioned that if the old condenser has failed completely open circuit, then there is no need to disconnect it. That is true. However, condensers commonly fail in other ways, and it is nigh on impossible to tell whether a condenser has failed open circuit without disconnecting it from the LT winding. Having disconnected it, there's no point in reconnecting it again.

In this section of the web site, we have set out step-by-step instructions on how to perform a condensectomy on a Lucas K1F, K2F, KVF or N1 magneto or an MO1 or MN2 magdyno.  If you wish, you can print out printer-friendly versions of the instructions and take them to your workshop. Alternatively, you can use our Armature Service or Magneto Service and we will do the job for you. If you are working on a BTH magneto, please follow the Lucas instructions, but bear in mind that there are some differences with the BTH instruments.

There are a number of procedures involved, as listed below.

 

PROCEDURE

  • Removing the magneto from the machine

  • Removing the magneto armature

  • Choosing whether to perform the condensectomy by either:

    • The 'quick snip' procedure (often not possible) or

    • The 'complete works' procedure

  • If required, replacing the insulator for the drive-end bearing outer race or replacing the oil seal

  • If required, replacing the insulator for the CB-end bearing outer race

  • Reassembling the magneto including fitting an EasyCap

  • Reinstalling the magneto on the machine
