what does the 5in1 graco 4605w crib look like when converted

Okay, this is how I solved the problem.  There is a small "wrench"-looking thing that comes with the crib and the trundle drawer.  You have to take the wrench and put it around the rod between the wheel and the leg cover on the crib (where you inserted the caster).  You have to pry between the wheel and the leg cover and it pops off. 
Three of mine came right off, the fourth one took some "mmmmph" to it (and about 3 minutes -- a major pain in the booty).
Hope this works for you.

Most if not all of the simplicity brand drop-side cribs have been recalled, including the Graco 8740.

Here is the CPSP link regarding this crib:
http://www.cpsc.gov/CPSCPUB/PREREL/prhtml09/09260list.html
http://www.cpsc.gov/cpscpub/prerel/prhtml07/07307.html

According to the CPSP information the company appears to be out of business to some degree and are not providing repair kits.

If you know where you purchased the crib, check to see what their policy is regarding recalled baby products.

We had purchased ours at walmart almost 8 years ago and were able to return it to another store in a different state for a full refund last summer. They did not need a receipt received, they just needed the manufacturer label on the part that the mattress lies on.

Because ours was older, the customer service clerk did have to work hard to find the crib in their system, but once she did, it was not problem at all.

Also, the bed is made to convert to a headboard for a full size bed and so it may be a little bit wide to work with a twin sized bed.

Most convertible cribs are made to function as a standards crib, a toddler bed and a FULL size bed headboard.

If you have access to the specific model number you can go to the following link and download the user manual for the specific crib you have. The manual should explain the conversion options for the bed.

The list for user manuals is after the user information form. You do NOT need to fill our the contact form to get a user manual if your model is in the drop down list.
