rubber disc for crankshaft dampener

Does anyone make and sell the rubber discs for the crankshaft dampener for the 308 engines?

  • I got a few from Eshelmans a while back. Some new but some weren't. Maybe I wasn't clear about what I wanted. I'd make a small wager that no one repops them. No $ in that one. They tend to be pretty well stuck to the hub or pulley surfaces so tearing one is easy.....I'll bet you knew that.

  • Yeah....crumby shot. Christmas cookies?
    I've decided that in the future, I won't dis-assemble any more of them unless there's a compelling reason to do so. They seem to be pretty much indestructible and I've yet to see one that was damaged by oil or such. If one is to modify it for attachment of another pulley (I think this is where the thread began) it would make sense to do so to get a good, accurate chuck-hold on the pulley, but if one is careful while removing the discs, it should go back together without any problem.
    I've got a small pile of them that have big chunks broken out of the front, thanks to people mis-handling engines.....some of which I'd already paid for. I hate that. C/I is brittle.

  • Good to have some solid, techy info.
    I may look like an amateur here but what's the critical element in the rotational alignment of hub and outer pulley? Since the two are mechanically independent, excepting the rubber discs, it seems there is no need to maintain them in their original position. Hudson apparently felt it necessary, so I'll go with it but I'm not seeing the importance.
    Call me lazy, but I've just used a medium strength Loctite (blue) for the center capscrew. So far, so good, but don't see a downside to that approach, aside from being not "correct". I just tell people not to look at my bolts....or my nuts.

  • I have sometimes wondered whether or not the entire combo was balanced after assembly. Hudson may have done that and did, as I understand it, but crank, flywheel;, clutch and V/D often get interchanged between various engines over the years. I can't say that I've ever heard of any extreme cases of imbalance due to "mixing and matching" of those components.
    The 212 in our '47 now has a different block but I kept all of the original rotating assy components as they were. I matched rod weights, being particularly careful to match weights of the "big end". At idle, It passes the "nickel test" as long as I can find a nice, new, crisp one.
    In my experience, there are few dampeners that haven't seen abuse at the hands of a hammer-wielding "mechanic".
    Enough,

    Ken Cates sent me a link to check out-- http://www.damperdoctor.com/
    I called and spoke with John and sent the damper to him for rebuilding and also making a double pulley setup in place of the original single pulley one. They ballance the damper as well.
    Also sent him one off an R2 Studebaker engine.
    Will report results when finished.
