Product review (5 stars): Fits perfectly after removing old metal insert that had remained on shaft on dryer
Perfect! Even though we couldn't tell from the listing, it had the same numbers on the back as the old, cracked one.  13318733, KIP-2198.  Only difference is the indicator mark is black instead of blue.

At first it seemed not to fit flush as others had commented, but then we noticed that it had a metal insert that the old one didn't seem to have. We found that the old one was still on the shaft attached to the dryer. After we very easily removed it with pliers, the new one fit perfectly.

Does seem quite expensive for what it is, though.
