MILLISH DIESEL RESTORATION

Here's the engine as we received it from Adrian.

Now we'll dismantle it and see what needs to be done.

OK first up is to clean everything and then determine exactly what needs to be done, apart from the obvious zero compression.

Here's the case all cleaned and the crankshaft reassembled with the front end.

With a really good cylinder liner to case fit we can now just move straight into making the replacement piston and contra.

So the cylinder liner has a couple of nasty grooves made in it from a very loose fitting gudgeon pin and a good look at the port placing leaves us with a bit of concern as to the viability of the engines performance so I think some rectification work on the ports is required.

Cylinder liner reported and the grooves lapped out.

All finished and ready for the new piston and contra to be fitted.

Here is the new piston and contra piston blanks all ready for final machining to size and final fitting to the cylinder liner.
