So I saw a guy making repeat timers out of a regular 24 hour home timer. He had instructions up but no matter where I went, I could not find the exact same timer he used. It has to be a 3 prong heavy duty timer to be able to handle a pump of course but all I could find in these specifications was the GE heavy duty timer model: 15429.
So I decided to use this timer and figure it out myself by figuring out the gear reduction within the innards. I am a certified mechanic and this shouldn't be too hard right?
These are available at Target, Lowes, home depot, Wal-Mart, etc. So here goes the instructions. Lots of pictures so hope this helps someone out there. They cost about $10 which is a heck of a lot cheaper than purchasing a repeat timer. I always have a spare one of these on hand in case one fails. Don't want my plants dying.
So the timer looks like this.
Now it has these weird 3 pronged screws. I use a small flat end screwdriver and it seems to fit between 2 of the flutes and allows me to remove them.
So after the screws come out, it should just come apart easily.
You can clearly see the gear box assembly at the bottom of the timer.
The gear box just lifts out
Using a flat blade screwdriver, pry the tabs up gently and break the box into the two halves.
The magnetic drive for the motor should lift out.
The gear box internals look thusly!
