87502 Bearing Orientation in Thunderbolt Chopper
Posted: Wed Jun 07, 2023 6:19 pm
Hey everyone!! It’s been a LONG time since I’ve posted on here. I’ve been out of the siren hobby for about 8-9 years now after I sold ALL of my previous siren collection. A week and a half ago I purchased and picked up the former West Lafayette, IN City Hall Thunderbolt siren from another member here in MN. I will be restoring it soon here. I purchased new 87502’s for it and am wondering what direction the “bump” on the inner race faces (siren was fully disassembled when I purchased it). When you answer, please envision the chopper in the “installed position” for clarity. I’m looking for the “bump-out” location for both upper AND lower chopper bearings. Another member and I were talking on Facebook messenger and he said they both face the sky. I want to confirm that before I install them and run this thing. I don’t want to mess anything up over something so simple as bearing orientation.
Thank you!!
