Tight gudgeons

[Graham Barker]

I have bought some new pistons for my Ruby. They are old stock and hence could be more than one decade old. The gudgeon pins are so tight in the pistons that they can't be pushed out by hand. They can be shifted a little using hammer and brass drift.

Is that normal for new pistons?

I guess that I can get the pins out easily after heating the pistons. But as the pins will be so tight after reinstalling, how can they be lubricated ready for starting the engine?
