    A buddy of mine suggested to fill in the pitting on my T98 spacer so that it will seal against the oil seal i have. How should i go about smoothing it out uniformly so that i will not have sealing problems. I know i can put the JBWeld on, but i do not think i can get it smooth enough.

    Thanks!!!

    Put it on with bondo paddles, let it cure then sand the surface down even with the surface of the spacer. I'd also prime and paint it with a good engine enamal. Just make sure the jb weld cures comepletely. Have used it for stuff like die/pattern repair to sealing tractor and forklift blocks in pretty much the same way as descibed. :v6:

    Couldn't think of the name when I posted previously but Devcon make a product thats much like JB Weld but it's machineable you can find it at an industrial supply. Either will work for what you want to do. You jut got to remember that it has to be as perfectly clean as you can get it before you put it on

    there is one more option, turn the shaft down and make a brass sleeve slightly undersize on the ID.. heat the sleeve slip it on and let it cool.. this is an old school way that works perfect.. just gotta find a machine shop to do it for you but it is a permanent and perfect solution..

    Thats some pretty cool stuff Mike. I might get some of it to have around. fortuantely the spacer the seal "seals" on will not see much heat because it is in between the gear boxes.

    Dan: Might get some of this from the local marine supply house. I've, and my Uncle who owned a boat shop, have used it since the early '60's. I've repaired holes in the crank case of both Mercs and Rudes with it and it held till they could be replaced. Also great for "fixing" owner overtightened spark plugs that have stripped. ;)

    The only down side of it is that it is a 5 to 1 mix. You don't want to put too much catalyst in it or it gets sticky.

    Mike: I think I'm going to get some of that stuff too. Easire to carry as a quick fix. :)

    Smooth it on and then let it dry. Then sand it down smooth. If you really want to get fancy you could spread prussian blue over the entire seal surface and then sand it with a decent size block and sandpaper. This would let you see the high spots and sand them down smooth ;)
