Heat Exchanger Collar trying to escape

Discussion in 'Mech Tech' started by olnow, Nov 8, 2014.

  1. Type 4 engine, early type heat exchange collar at the clyinder head has come off.

    I assume I can get this welded back on - any tips?

    Worth doing?

    Do I need to seam weld all the way round, as it seemed to be only tacked on in a few places ?

  2. Just along each flat side is fine... But you will need to clean it back to shiny metal and turn the welder up to max to get good penetration :cool:
     
  3. Thanks Paul,

    I'll get the welder cranked up then....

    Does it rely on the interfence fit to seal, or should I shove a little bit of exhaust paste in there?

    Sorry for all the questions!
     
  4. Normally they are an interference fit, so seat it with a few taps from the hammer!! :)

    Zed Gradually getting grumpier

    Just make sre you get it flat and level with the other one or it'll blow.
