It sounds as if you have enough knowledge to rebuild the engine yourself. The most important thing is measuring the components and making sure you are not re-fitting parts that are excessively worn.

To remove the engine, remove the starter motor and unscrew the bolts holding the coupling to the flywheel. Then remove the flywheel housing bolts so that the housing is disconnected from the engine, then you can pull the engine forward enough and pull it out. If you have a engine hoist, pull from the top, if not drop it out from below.

Remove the rotor arm and sleeve and oil filter first as these parts always hit something otherwise

Before you remove the engine, loosen the crank pulley bolt as it's easier when the engine is bolted to something solid (like the car!)

Pull the crank out when you have it apart and measure the thrust faces..it will need another crank or metal-spraying to bring it back to the correct size.
