Salvage Pump Handle Repair
By Aqua Flash
07/03/08
I recently received a CPS 1700 that had no pump or handle. I had some spare pumps and found one that went in well. After doing some things on it to make it good again (it involved mostly replacing its nozzle assembly, see the PVC Nozzle Modification), I was left just needing a pump handle, as it was damn uncomfortable without one let me say.
What you need:
A standard CPS pump (or you could make your own, however I didn't need to do that so I cannot guide you from beyond there)
A pump handle from another soaker you are not bothered about (I used a salvaged CPS 1000 pump handle)
Drill (drill pieces of about 1/4" size)
Screwdriver
Get your pump handle and line it up with the pump shaft. The hole in the pump shaft here was too small and also not far enough out, which meant if the handle was put through here it would touch the pump cap before the rubber seal would touch the start of the pump tube, not fully maximizing its pump volume. This meant a new, bigger hole had to made further down.
Now, you need to get to the workshop and drill to the left of the hole. Do it carefully, as both sides of the pump shaft need to be level in order for the handle to get a good fit, or even a fit for that matter. If it goes a bit wrong and isn't fully straight, then drill to the side a bit to make the sides even, this is what was done here since I don't have a drill press yet. Smaller sized drill bits were used first as a precaution for if things went wrong you can remedy it. The size you should really go to before stopping is 1/4."
From here the part in the handle with the screw to the right (that goes the rough the hole on pretty much every normal CPS gun) should nearly go through. Keep filing it until there is agood fit and the part inside the pump can go through. Once you have done this, then you can screw and seal the parts together. You now have a pump handle!
Put the pump back into your soaker, and now pumping is a heck of a lot more comfortable.
The pump handle however will still be a bit wobbly, so watch out for that. I'm working on reinforcing it when I get the material for it, however for now this is a good temporary repair that works well for me.
