Very good pictorial, I'd like to suggest a few tips for anyone contemplating a rebuild, it applies to all diesel engines.
It is good practice to remove all the casting flash in the sump area of the block, there was a fair bit of it in this engine, a small die grinder and a couple of hours will prevent any damage from bits of flashing breaking off.
If you have the head skimmed the machinist needs to recess the valves into the head to maintain clearance.
It is also good practice to Plastigage the crank journals to check for correct clearnces and if the crank is ground undersize make sure the machinist maintains the journal fillets to factory specs.,
Always bore fit new rings to their bores and check ring gaps, do not rely on the sizes printed on the ring packaging/brochure, better to be sure, Regards Frank.
