    Interesting. The Navy has, (or had, don't know if they're still in service) 7 or 8 T-ATF's, (ocean going tugs) run by MSC. They have a pair of 20-645 EMD mains and Liaaen CPP, (controllable pitch propulsion) systems. The hubs and blades were stainless castings.

    Inside the hubs and shaft lines are brass parts which wear. Every four or five years at a major yard period the blades are removed and the hubs and shaft lines pulled. Once off the ship hubs are removed from the shaft and oil tubes pulled from the shafts. Everything is disassembled and inspected, wear parts and seals replaced.

    A pair of hubs from one of them had major erosion's and pits on the flange face where it was bolted to the shaft flange. Also looked like the hubs also had porosities in the castings.

    Long story short, “Higher, Higher” approved filling in the pits with Belzona, (its ABS approved) and sanding flush with the flange face.

    Silly question/suggestion/thought: why don't you trim the end of the broken tube, clean up the area where it broke off, and slide the piece into the hole as far as possible, then use whatever adhesive you decided on. Seems to me the joint "might" be stronger as there would be additional support with the tube inside the hole instead of sitting on the exterior. Does that make sense??

    It does! Outside the box and a fast temp fix. theres no pressure there, you could just stick a tight fitting rubber hose in there without even removing it.

    Winner

    Don't underestimate the strength of JB Weld and other high strength epoxies. If prepped properly it will stay together indefinitely. Like I posted earlier hang onto the new replacement part in case the other valve fails.
