The needle bearing requires special tools for disassembly and lubrication.
Your dealer will need to perform this service for you. The bearing is designed to run for up to 6 - 8 hours a day 5 days a week. To extrapolate that would be about every 30-40 hours and if you don't use it that much in a years time at least once a year.
