Done and Done! Thanks a bunch PDuff, Chat, and Willie! I love this place! Also great peace of mind knowing that this is a "new" (ha!) and improved part!
First one took about 30 minutes. Second one about 3. For the benefit of anyone else who happens upon this thread and is going to try to tackle this without the requisite experience (like me!), here's some tips:
1- you won't be using ANYTHING on that side of the rack. The "Adjuster" is everything from the wheels all the way up to the plastic handle on the top. On the first side, I gingerly pried ever clip lose so as not to break anything. One side two, I just let loose and snapped everything into oblivion to remove it in 30 seconds (make sure you don't damage the rack itself though!)
2- the instructions are OK, but unlike Ikea, they don't give you a parts ID chart. They just assume you know that everything is. So, based on that picture above, here is what everything is:
A- Top Left: Adjuster Arms
B- Bottom Left: Positioner Clips
C- Middle: Adjust Body
D- Top Right: Adjuster Covers
E- Bottom Right: Adjuster Actuators
Everything EXCEPT the Adjuster Actuators are symmetrical, meaning you can use either part on the left or right sides. More on that later in step 9.
Some instruction sheet addenum:
Steps 5,6,7: The pictures are a little dark on my sheet, so it was hard to tell the orientation of the positioners. The correct orientation is with the slot facing DOWN, and the bottom clips (that go around the rack tines) face the OUTSIDE (i.e. away from the dishes, and of course the top clips will face the inside.
Step 8: The vertical part of the adjuster arm actually slides up into the adjuster body about halfway (good for now) and is the action used when adjusting the rack height. So at this point the body and arm are actually 'connected'.
Step 9: The picture of the actuator shows the 'thumb pad' facing the inside (dish side) of the rack. If yours faces the outside, well then you've got the wrong one. Grab the other one and it should look like the picture.
Step 11: Don't force it clipped shut! I did that on my 2nd side and a little plastic tab from somewhere broke off. I think it's just the tab to keep it temporarily shut, which the screws do eventually, so it doesn't seem to be affecting operations. Still, I'd rather not have broken it off!
Step 12: The screws are torx. If you don't have a torx set or bits, get one before you start!
That's it. Easy Peasy. The wife is happy again, and I'm happy that this cost my only 40 bucks.
Thanks again everybody. I love this place!!
