To this day, this is the mechanism whereby ball an roller bearings from CBC or Bearing Services have the CAR 30 holy water sprinkled on them, turning them into "genuine aviation spare parts".
They are Timkin bearings, same part number as those originally fitted and were approved by a CAR35 organisation. No holy water was involved. Each bearing had to be inspected to ensure dimensional conformity. was to do with the internal and external dimensions. Fitted to Bell 47 tail rotor drive shaft.
Some of you will remember some unfortunate accidents to a particular model of helicopter, because the manufacturer apparently ran out of "approved" bearings for a rotor, and fitted SAE standard bearings.
NO!! It was an R22 Transmission that an organisation in NZ(check me on location Beeza) fitted because they were a cheapskate dodgy organisation, had fk all to do with Frank's factory.
