Disconnect the hoses by removing the hose clamp then sliding the hose off of the hose adapter. Place the hoses over the swimming pool wall so that the water doesn’t drain out of the pool.
Once the thru-bolts have been removed, the pump housing can be removed. Make note of the pump housing position before removing it. Place the pump housing face down and use the tip of the screw driver to push the shaft seal out. Be careful not to push on the plastic seat that the shaft seal sits in.
Turn the power on to the pump and check for leaks. If these are any leaks, turn off the power to the pump and repair the leak.
