Most new heater fan motors are coming with that seal.  You could remove it and add some lube, but I really don’t think it’s necessary.  The bushing is a bronze oil impregnated bushing and should be good for life if not attacked by dirt, the reason for the seal.  Before they came with seals, I always glued on a plastic bottle cap to protect that bushing.  The very first thing the dirty air coming in the van hits is that bushing !  Here is a bit of an instruction manual I made up, but you seem to be doing well on your own.  This is one of many technical article I’ve published on the home page of my website: www.frankcondelli.com

      Please note that I will be away from my business travelling from December 01 until April 30, 2017.  Parts orders will be processed although not as quickly as usual.  I will always be available for contact by E-mail.  If you phone your call will be addressed by Steven and he will either call you back or advise you to contact me directly by E-mail.  

Cheers,
