Thanks. Hopefully others will chime in, but those are the letters I was trying to remember.Looks like a PYI drippless shaft seal. Not a cutless bearing at all.
Is only a stuffing box with packing a cutless bearing?Looks like a PYI drippless shaft seal. Not a cutless bearing at all.
anyone want take a shot at that anodes usefullness ?
Not being used as an anode, it's a safety to keep the SS shaft seal from moving away from the carbon face seal.anyone want take a shot at that anodes usefullness ?
BalanceWhy not just put a hose clamp there and save the rotational weight of the zinc?
I think the manufacturer does not recommend using a zinc as a retainer, since it may erode. At least that was the case when I spoke with their tech folks a few years ago.Not being used as an anode, it's a safety to keep the SS shaft seal from moving away from the carbon face seal.
I doubt the weight of a hose clamp screw will have any effect at the speeds a diesel shaft turns.Balance
True but they could easily be unbalanced by the gram or two of unbalance a hose clamp would introduce.These coupling look like they have pretty symmetrical mass distribution. Maybe not ported & polished, but close
