KEILKRAFT K6 RESTORATION

Here is the engine as we received it from Adrian.

Let's get it dismantled and assessed for repairs.

Oh Boy, what looked like a not so bad engine on the outside had some hidden rottenness that will need to be removed in order to bring this old English gentleman back to a state of good health and running order.

 

Apart from a good clean the main issue that needs resolving is the obvious broken piston and a seriously flogged out rod and gudgeon pin, which has left the liner not to bad but definitely needing some love.

First step is to clean everything up and prepare the good parts to be reassembled once the replacement parts have been manufactured.

OK so having cleaned and measured all the other main parts we've found further issues.

Unfortunately the crankshaft is badly worn on both the main journal and the big end which has a 0.1 taper towards the back of the engine worn into it so the rod is going to always want to rub against the rear face of the case if this is left untreated.

Sooo a new crankshaft will now have to be manufactured and so we will take the opportunity to make it as a 1 piece unit with slightly altered flywheel layout.
