shallow Well Piston Pump Repair Help Needed

I have an old Southern Industries Ltd piston pump model 8250 similar to a Duro K255.
I can easily replace the pump's rubber valves, springs etc but I can't get to the worn leather piston cups to relace them. I have removed the end plate assemly in the pumping chamber exposing the end of the piston chamber and the cups and what looks like a slotted bolt or screw. when I try to unscrew this bolt the piston rod also wants to turn . I'm concerned that if I apply too much force I will break the piston rod or cam. Will I be able to access both leather cups somehow?

Many thanks in advace.

The rod is meant to unscrew. Unless you can hold the other end of the rod just unscrew it as an assy and then you will be able hold it in a vice and unscrew the the leathers. If the rod is worn replace it to prevent leaks. also replace the packing material around the rod.

New well pump installed, not working quite right

Hi everyone, I installed a new pump for my well that waters my lawn. We have 2 wells, not connected to each other in anyway. One for the house, one for the sprinklers. It is a Flotec FP 5242. 2 problems that I need some help with. When I turn the pump on, I have to prime it. It takes a few minutes but it eventually draws water and the sprinklers go on. I let them run a few minutes and when I turn the pump off, it sounds like water is "falling". It's the only way that I can describe it. I usually have to re-prime the pump to get water to the next zone. I have cycled through all 6 zones numerous times, letting the system run a few minutes in each zone. I've replace/fixed broken sprinkler heads. I'm not sure why I have to keep priming the pump each time and why it doesn't start the sprinklng right away. Second issue, probably unrelated is electrical in nature. The pump is 240v. From the circuit breaker the wires run into a box that contains a light switch to turn power off or on to the sprinkler timer. I connected the 3 wires from the new pump to the timer the same exact way that the old pump was connected. The mechanical timer has a switch on it. Up is for the timer to control the pump on/off automatically which is what I want to use. Center is off and up is manual on. When I turn the light switch on to turn power to the timer, the timer runs the pump continuously even though the pins are not activating the automatic switch. Could I have the 2 non-ground wires from the timer to the motor backwards? Will it damage the motor to reverse them? Or do I need a new timer? Thanks! Greg

I have to replace the pump in the holding tank for the septic system (pumps to a raised bed leach field). I just did this for a different tank just 6 months ago. I had this problem with the pump I bought, in that the pump plugs into the float, and the float plugs into an outlet, creating a T shape with the electrical wires. In order to use this in the tank, I need to water proof the electrical. I know there is shrink tape, would this work for this situation?
