    Default Belt Lagging for 12 HD

    Getting set to put lagging on my front and rear pulleys. Was the lagging held on with flat head brass screws? That is how the one I took off was attached. Would it be a good idea to soak the lagging in water before attaching? The idea is that it might shrink when dry and
    pull down tight.....or would it just pull the seam apart?
    Any input appreciated....Rod

    Yes, flathead screws were used. I have always put the lagging on dry without a problem. Interesting thought putting it on wet, though.

    Thanks for the input. I think I'm going to get the lagging screwed down tight,dry and then wet it and see what happens.........

    How did you make out with the belt lagging Rod? I just read in a 1911 Motorcycling magazine, that guys were wetting their belts back then.

    Default Belt Lagging

    Hi Cory.......I got the belt lagging on ok. I turned the heads of the brass screws down on the lathe. The standard head size looked too big. I put the leather on dry, but wetted the spots where the screws mounted, so they would counter sink in easier. after every thing was mounted, then I wetted the entire rim. I can't say that after wetting , it tightened up any, but it did'nt hurt....probably won't have the bike on the road for another year...Rod

    Here's one of the quotes I found. If nothing else they may be of interest...........

    "For lagging the pulley on my flat-belt machine, I have tried sole leather, common leather, canvas belting and Raybestos brake lining, and have found sole leather best when put on properly. Always soak the leather well and put it on wet; when it dries it certainly is tight."

    Another one says "I have fitted a sight-feed oil cup on my machine in such a way that it feeds belt dressing onto the flat-belt pulley. I find it keeps the belt in excellent condition and causes the belt to hug the pulley, even when quite loose."

    I'm trying to recall, are you still gathering pieces for your '12 or are you just working through the restoration process? I'm sure most of us can relate to the time factor.

    I've found almost everything I need. Eng,frame handle bars,seat, hubs and clutch are orig.
    The rest is repro or things that I made. Now the chalenge is to make all this stuff fit and work together....This project started about 25 years ago, with the purchase of the engine.

    Hello , I have a 1912 belt drive Excelsior single 4B , have used the 'back side' of leather (suede effect) on the pulleys , and use a leather belt I fashioned from an old stationary engine , it's lasted for a few hundred miles but does stretch about 1-1/2 inches after a run , nearly shrinks back to the original length over about a week but over time is slowly getting longer ! It's interesting c.o. about the belt dressing drip feed , do you know what is the best belt dressing to use for belt drives , best wishes with your rebuild Rod K , you'll enjoy the ride when completed . Many thanks and may all your miles in 2009 be big smile ones ! , Ken

    Hey there Ken,

    I'm not sure what the best dressings are.......maybe Earl,Exeric or Jurassic might know. I'm still laying in the shadows waiting to pounce on an early machine to play around on! I still think that Excelsior of yours is pretty darn cool. It's also nice to hear it gets ridden. You've posted the pics to prove it! Great stuff!
