I too have ordered & received a replacement lower shelf for our dishwasher. It also came with these two tines & NO DIRECTIONS.
From reading your customer questions, others have had to order this clip (#99001436) which I have ordered & received. My husband cannot figure out how to attach the tines with this clip. Do I need to order another clip? But where does it go?
Please send a picture diagram to attach the clip!
Answer Diane, You will need two(2) tine clips  to install the tines. Using the parts diagram as a reference, The curved palstic side of the clip will face away from the tines. you'll align the clip in the bottom of the rack,slightly to the right of the bottom wrungs and slide the clip to the left until the clip on the bottom right end of the clip snaps and locks around the wrung. The clip on the bottom left is an open clip (like a fork) and will move into position and encircle the wrung when you slide the clip into the proper position. Then you can snap the tines in position on the upper clips of the tine clip. These are delicate components, and you need to be careful installing them.
I have received dishrack (whirlpool) WPL 99002572 with tines and clips 99001436 and have read all the quesions and answers here but still have no idea how to place tines. Would you please send some sort of picture for me to go by? I have been struggling with this for a month now!
Answer Valaer, after further research and speaking with the manufacturer directly it seems that the rack 99002572 is the racked used on your appliance however, the tines and clips for this rack are no longer available. The tines and clips sent with the rack were mispackaged from the manufacturer and will not work on this rack. We have further researched other rack tines and clips and have found that none are available for this particular rack. Sorry about that!
I want to replace part APA114268. I unerstand it comes without wheels. Will I be able to transfer the wheels from the old rack the new one? By myself?
Answer Fred, the original lower rack 99002572 wheels can be transferred from the original rack to the new rack. The wheels should snap off and onto the new rack. Thanks!
We have received rack #4114268 and clip #'s 4113042 & 4112831. We can not figure out how to clip the tines on to the rack on the rails. Please send us a picture showing how it works.
Answer Hello John! Here is a link to the picture of the tine clip needed to install the tine. The picture shows the clip downside up. You will want to turn it, so the upper part in the picture attaches to the actual dishrack and the tines to the ends left on top. I hope this information helps you, thanks! http://www.appliancepartspros.com/partpic/Z3BqLjFfZ2xfNjM0MTAwOTkvTFBXL3NvdG9ocHRyYXAv.jpg .
Where and how do the tines attach? They are much longer than the tines of the original model which where incorporated into the rack itself w/o attaching parts. Please help me out on this.
