TR2/3/3A TR3 Engine Noise trouble. New to Triumphs. Granfather's Car. Need Help.

I agree. If you look inside the pulley, there should be a protrusion that should get clamped firmly against the bearing inner race. Lots of people have reported finding that they had to grind (or file) the housing to get clearance.

Without the pulley clamped against the race, you are relying on that slip fit to hold it. It will eventually work loose again and you'll be right back where you started.
 
FML. I'll have to take it to my dad's house and work on it. I couldn't do it again at my grandpa's. I could not find any tools and especially room. I had no room to work on it in his garage.
 
Yep, I ground a little notch in the body of the water pump housing to provide full clearance for the pulley once it is fully seated on the shaft. There is plenty of excess material there so no worries of harming the housing.

I am going to have to take another look at my water pumps. I could swear all the ones I worked on we're bottoming on the shaft threads before the pulley hit the bearing. It would make infinite sense that they should bottom on the bearing race....
 
Another noise maker is the chain tensioner in the timing cover. A friend of mine lost his mind chasing down a somewhat intermittent noise. Turned out to be the tensioner and chain needed replacing.
 
I’m looking at these posts about the water pump. They’ve got me wondering. I’ve never installed other than by inserting the “key,” and sliding the water pump cover over the inner housing, and then tightening the nut. I’ve never thought to go back and check how tight it all becomes, or if later it somehow loosens up. Is there really a problem? Is the TR4 any different from the TR3? Great excuse to see old posts from Randall the Master, the Teacher.
 
I don't think there is any problem with OEM, and like OEM, parts. The problem comes when some of the Repo pumps used different shaft designs. If you inadvertently mix and match OEM and later repo pumps and pulleys...then you need to look closely at the assembly.
 
Possible the pulley has worn a groove in the shaft. Hence it being a loose fit but tight where the shaft isn't worn ie where your trying to pull it off. I would suggest a new pump and pulley is in order. If you do manage to drag the pulley off the new pulley will be just as loose.
