Help with Rebuild of cat pump on 370ss

I have a cat pump 3cp 1120 on a 370ss that is leaking water. There is also water getting into the oil in crankcase. I have ordered new seal kit and oil seal kit. Wondering do I need to remove the pump from the machine to do this or can I just remove pump head and not touch the rest of pump. Never done this before so any help much appreciated.

You do not need to remove the pump body. Pull the wet end and clean and repair it in a comfortable environment. Drain the oil while doing so and reassemble. It's a tremendously simple design and doesn't require a technician, just need to pay attention to the direction of certain seals, pretty easy.
