    Has anyone ever heard of or used Belzona products?

    A friend gave me a Belzona 1111 epoxy repair kit and after reading up on it, I’m wondering if it couldn’t be used to repair the grooves worn into shafts caused by the lip on the seal. If so, it would be a lot quicker and easier than welding/machining or sleeving a shaft.

    After going onto their website and clicking on the 1111 product and watching their repair videos, I’m thinking it might be possible.

    I’ve looked up the product in the past when I was looking for options for the type
    of drive shaft repairs you mention. I believe it was relatively expense, which might
    be okay if it has a long shelf live, as very little would be needed for mentioned repairs.
    Also, I wonder how abrasive the repair would be for a rubber seal area?
    One thing sliding a bearing over a repair area, may be another a rubber seal?
    Here’s a YouTube video……

    I HAVE USED BELZONA IN THE PAST AND BEEN VERY IMPRESSED WITH IT’S RESULTS. FOR YOUR APPLICATION HOWEVER, I WOULD GO WITH A SPEEDIE SLEEVE. THEY ARE VERY THIN STAINLESS STEEL SLEEVES THAT WILL COVER THE WORN AREA. THEY ARE FAIRLY EASY TO INSTALL ALTHOUGH THEY ARE A LITTLE PRICEY–(20.00-30.00) DEPENDING ON THE SIZE. LOOK THEM UP, THEY’RE PROBABLY JUST WHAT YOU NEED.

    There is a well-respected shop in my area that uses it to repair pitted hydraulic ram surfaces, with good results, when that’s the only solution. We have repaired a few rotted through aluminum engine blocks with it and the repairs have lasted for a good number of years, in salt water. I think it is better than Marine Tex, by a mile. I dunno about running a seal lip on it, though; and the stuff is very expensive. But I will definitely be looking forward to your results! I ALMOST used it on a badly pitted, 1970 4 hp Merc driveshaft, but finally figured a way to make something resembling a speedi-sleeve. (Before anyone asks, it took like a zillion hours of experimentation and work, to save a $50 motor. It was more the principle of the thing. Actual Speedi-Sleeves are not available in a size that small.)
