How to set factory water pump pressure, pump cut-on?

What should I check before starting a pump?
Start the unit. Be prepared to stop the unit immediately if anything does not seem right. Check for proper pressures, flows, temperature of oil and bearings, vibrations, and noise. It is good practice to recheck the alignment after the pump has been operating for a short time.
Can a person make a mistake installing a water pump?
During the course of water pump replacement, it’s possible for even the most experienced tech to make a mistake that will lead to premature pump failure. Here are four common mistakes that even a pro can make installing a water pump.
