water pump location for this specific size engine

i thought the water pump was behind the pulleys mounted to the crankshaft but once all three pulleys (or two pulleys and harmonic balancer?) were off i see a large iron mounting bracket for most stuff on the front of this engine and also behind it another sheet metal cover.
Is the water pump behind all this stuff?
Will i have dismantled timing components before they're free to come off?
I'm a little overwhelmed here.
Thanks for any help.
