Title: New pistons
Post by: JohnMillham on 10 July, 2014, 10:18:03 AM
My new pistons have arrived and look fine. They are lighter than the ones I removed and higher compression ratio. I was surprised to find that the gudgeon pin slides in when the piston is at room temperature, as I have always had to warm the pistons up previously. I gather that is now normal practice. So I'll be off to "Vibration Free" soon.
Regards, John

Having never seen an original Lambda piston, how different is it ?

Certainly looks very nice ..... and modern !

Not sure how original it is, but this is one which came out of my car. The new ones are lighter and with a higher compression ratio.

Paul at Vere Lancia had them made for me. He's in the Netherlands, but it looks like they were made in the USA. I'm having a set made in the same "style" for my Augusta.

The USA is also a good source for Aurelia pistons. Good quality, prices and delivery.

I'm having the devil's own job of fitting the "circlips", which are simply bent wire, but very strong. After spending pretty well all day yesterday, I have one piston on its rod and very sore fingers. I tried making a special tool, but it doesn't work. What's wrong with proper circlips? They even weigh less than these horrid lumps of wire!

I eventually modified the tool and it now works. No more bruised fingers and thumbs. Pistons and rods are now in the engine.
