FItting pistons to A series Mini engine


After fitting the crank, it's time to fit the con rods and pistons.  These are new pistons made by Hepolite and are really good quality.  
They have to be pressed onto the con rods.  
As you can see the engine block is now painted.   I used a high temperature paint bought from Halfords and there are about 4 coats of paint.  Hopefully the paint will protect it for many years.  I hate rust so want to make sure water has no chance of getting under the paint.  

The piston ring compression tool was ok but it wasn't very good at the compressing the last little bit it get the rings into the bores.  

Music is by Orbital and is called Attached.

Mini/ MG Metro engine 1293cc rebuild

This is a part of the rebuild process of one of my Mini engines.
It's been sent off to Rob Walker Engineering, which is a bit South of Oxford, England.

Very nice chap I may add.
The block was acid dipped to remove dirt and oil.
Rebored after a hone wasn't enough to remove some pitting on the bores.  Bored out to 1293cc which meant buying Hepolite pistons from Min Its near Solihull. (very nice people as well)

I bought some new crank bearings and opted for lead/ aluminium bearing rather than the race type Lead Indium bearings because I know Indium is a very soft metal indeed and wasn't keen on another rebuild soon.
You can scratch a crank bearing with your fingernail so care has to be taken when handling them.

Hope you like the little video.  Engine building is expensive but great fun.

cheers,

Rich
