This product looks like it includes something which will slide over the shaft and repair a cracked motor shaft. Not true. The shown white shaft is actually just for shipping. I wasn't able to use it because of this and had to get a new motor for my dishwasher instead. If your shaft is good (unlikely) but your seal is bad, this repair kit should work fine.
