Ok most of all that just went straight over my head! I never touched the oil or water pumps, just took the alternator and cambelt pulleys off. I've no idea when the oil or water pump may have or where ever been changed as the donor had very little in the way of service history.
I can confirm I only have 1 thrust washer which is sitting between the block and cambelt pulley with the raised part of the washer pointing outwards away from the block so to speak.
It does have a rather thick & large washer which sits between the bolt head and the front of the alternator pulley. I guess what seems really weird is I can do the bolt and thick washer up on the crankshaft fairly tight without the alternator pulley on and hand cranking the engine is fairly easy and smooth. Then when the alternator pulley is put on without the bolt done up, again it hand cranks easily with little resistance. It's just when I then start to do the bolt up tightly with the alternator pulley that it get's hard / impossible to hand crank the engine depending of how tight I've done it up. At the moment it's only just hand tightened lightly for the engine to be able to start up like that.
In theory tightening the bolt with the alternator would be either pulling the alternator pulley into the crankshaft or pulling the crankshaft & cambelt pulley out? Also I guess the tension would be spread out across the alternator pulley because of the thick washer?
Out of curiosity I'm guessing it's not a good idea to just run the engine long term with the bolt not fully torqued up? It must be sitting around 20-30nm at the moment vs the 120nm it should be.
