I didn't make the "hub seal tester" grade yet... but on friday and saturday I put new seals on 3 of my 4 hubs, repacked and reset the bearings, etc.
I purchased 3 different types of hub seal from Paddocks, as an experiment.
1 is the ~£4 RTC3510G old-school OEM metal casing with leather lip. They look really old, but came nicely wrapped in oil-saturated paper. A pain to fit, even with liberal pre-greasing on the seal surfaces, because it was so stiff to get seated that I had to use the 1st bearing nut to gradually screw it on. I am hoping that it wasn't ripping in any way as it went on. I was really glad I took digital pictures of the exact bearing nut positions before dismantling for reference, because the new seal friction made it really hard to feel what the bearings were doing as I was re-tightnening them. I just put the nuts back to the original positions but tighter 1/12th of a turn compared to "before" and it seemed about right (play gone when shaking the wheel violently after everything re-installed and back on the ground).
The 2 other seals are "Corteco RTC3510G?C? 1510065" which has a more rubber/plastic construction also for ~£4, and a much cheaper Karsons RTC3510 "Plastic" for £1.50.
Is there any opinion as to what seal type is the most effective these days? Is the "OEM Leather" better, or is it really only for purists these days, with better performance given from the more modern plastic-case alternatives?
I wrote down which seals went in which hubs so whichever starts oozing first will not be getting purchased again!
Can I get the "hub-seal tester" rating now ?
Today I am brewing 6 gallons of IPA and looking out at my vehicle from the kitchen under its lean-to as the rain pours down.
