New bearing needed size OD=26/Id=15/H=5mm unable to be found online. Closest to this isze is a 26*15*7mm bearing, however that might be too thick. On the other hand the original bearing has an Id of 17mm, the Id that we need with this conversion is 15mm. An option would be to do as I did and use something as a bushing to fill in that gap. Links to the bearing I used or a bushing that needs to be cut down to size can be fownd below.

Bearing used in the video (only inside of the bearing was removed and used a bushing) https://www.aliexpress.com/item/32841...
If the bushing does not fit snugly I advise that adhesive is used to secure it to one of the parts.

Important! With the impact mechanism from Dayi 2016 you can replace the original impact mechanism and leave the original anvil if you wish to do so! The Dayi 2106 impact mechanism is for an anvil with a 8mm opening at the bottom, same as the Parkside original anvil!
