Tom,
I have two PP in service, both on Rohn 45. For both, I fabricated a custom
rotator plate from 1/2" aluminum plate and pressed in a new seal that fits
the OD of the PP output shaft. I used a Chicago Rawhide (don't know what
their new name is) CR 33458 seal. Both PP are still working (for over 20
years), so I haven't had the opportunity to look inside to see if there has
been any water ingress. Also, both PP have a water shield mounted on the
mast above, fabricated out of PVC plumbing pipe stuff.
