After searching the internet for a long time I could not find much information on the break down, disassembling, and maintaining internally the Pioneer CDJ 3000. So, I made my own video for everybody to benefit.
It includes detailed information and specifics regarding the jog wheel, cleaning and maintaining, specifically cleaning dust in between the jog wheel screen and the clear plate on top. This video will guide you through all the steps needed to disassemble safely if followed step by step. The type of maintenance should be done every few years to keep the unit running in top shape and so they will last you a long time. Seeing as these units cost around $3000 each please be very careful. All the electronics and mechanisms are exact and tolerances are very high.
By watching this video you agree that I am not responsible for anybody's equipment but mine
