Easiest way is to remove all 4 gudgeon pin access bungs, two 14mm's at the front on No.1 and 2 cylinders and two at the rear of the engine - one 14mm behind the oil seperator/breather plate on No.3 cylinder and the oval shaped plate on No.4 cylinder.
Use a long thin rod to knock the front two gudgeon pins out going from the rear and vice versa to do the rear gudgeon pins from the front.

ps - you wont get to all the rod caps from in the sump.

A hot air gun on the top of the piston works a treat.
