raw water pump housing moves with engine running

[harmonicat]

2005 Volvo 4.3 GL-D when the engine is running the raw water pump housing wobbles around. Kind of like the shaft its connected to is not quite straight . Not lots but you can definitely see it. This is my first I/O and it was moving enough that I spotted it and asked the seller about it. He said it was normal. Is this normal or is the housing supposed to stay dead still while engine is running?

some movement on the pump is normal, just make sure that there is a black bracket at the pump housing. This bracket prevents the housing from spinning around on the crank.

I have same pump and recently replaced it. Mine wobbles slightly ( always as).
