Hello everyone, I have restored a Beogram 1203: removed the old grease, lubricated the bronze bearings, changed the belt, etc. I have a problem with the idler wheel, which wobbles up and down whether it is turned by hand or in contact with the bevel gear. It seems to be slightly warped. However, I replaced it with a new remanufactured part, cleaned off the old grease and lubricated the small plastic caps at the top and bottom that hold the axle in place. As a result, the rotation speed oscillates between 33.32 and 33.35 RPM, with the latter figure changing constantly due to this problem, I suppose. I can't figure out where the problem is coming from... I'm posting a video. If anyone has any bright ideas, I'd love your help. https://youtube.com/shorts/wC4_8SjGnOU?si=OptiMr_qqeLRwcUA Have a Merry Christmas! Julien Translated with DeepL.com (free version)
