Introduction

…And then realized the culprit was my wife, who did not know that the diapers should not be pushed through the trap doors.

What you need

Step 1

              Trap Door Side Support
  • Get your stuff together. You’ll be replacing one of the plastic side support tabs, just like the one I had already replaced.

Step 2

  • Unscrew these Phillips screws.
  • Remove white plastic retainer thingy.

Step 3

  • Unscrew these Phillips screws.
  • Now unscrew these Phillips screws!
  • Pull out the whole assembly.

Step 4

  • Use a 1/8" drill bit to drill through the center of the original tab location until you have a nice, clean hole.

Step 5

  • I added an extra nut to the head of the screw so that there’s a more substantial edge for the plastic can parts to press onto.
  • Screw the screw through the hole you’ve just created. It should stick out approximately 1/2" from the side of the mechanical assembly.
  • The 1/8" drill bit created a slight “interference fit” with the #8-32 screws, meaning that the plastic from the hole keeps the screw nice and tight.
  • Add a nut to the other side of the screw, just to hold it together.
  • Do not overtighten, as you want to keep a gap between the trap door and the side of the mechanical assembly.

Step 6

  • Perform a little test to make sure everything works as it should. The mechanical actuation should open smoothly and quickly.

Step 7

  • Put the assembly back into place (without screwing it in), and verify that the actuator pole hits the screws at a good location.
  • Adjust the length of screws if needed.
  • Put everything back together in reverse order, including all the screws you took out.

The same thing happened to my unit. I bought the same bolts (which you have referred to as screws) and nuts, drilled the 1/8-inch diameter hole and installed the bolts, making a few modifications. I used a #8 washer underneath of the bolt head instead of a nut as you did. I installed a #8 washer and nut on the free end of the bolt. However, there was not enough clearance to allow the mechanism to slide freely. So, I removed the washer and nut at the free end and reinstalled just the nut. With the small amount of additional clearance, the mechanism worked freely, just like new. Incidentally, the photograph that you have shown in Step 7 appears to have the free end of the bolt on the wrong side of the plastic piece that it is threaded through. The free end of the bolt needs to engage the curved slot on the other piece located on the opposite side. So, I was a bit confused, but figured it out. The 1/8-inch diameter drill hole worked perfectly. Just a warning to anyone: DON’T overtighten or plastic will crack.

Awesome man! Saved me $50 and we were so close to potty training we really didn’t want to buy a new one!

I did put the screw in from the inside out though, opposite of the picture, and 1/8 was a little too small for my 8/32 but I just reamed it out a little and Bob’s your uncle. I also cut the bolt with my angle grinder just about even with the other plastic tab that had not broken off.
