Metal shielded or rubber sealed bearings
I'll be replacing the 2 bearings for the fan on my '73 Panther. The current bearings are 6204 with metal shields so they're unserviceable. I've cleaned and re-greased other bearings that have rubber seals which can be removed for servicing. Can anyone think of a reason why I shouldn't install rubber sealed bearings in place of the metal shielded ones? I know these bearings will be subjected to more heat than the locations I've installed rubber sealed bearings such as the drive shaft and idler wheels.
