    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

4" over swingarm

I've built a gorgeous swingarm for my son's bike. I originally built it for a drag bike that never got built. There are no swing arm bushings in it because it would have been ridgid.
My question is this. I can forsee huge problems getting the proper stock type needle bearings. Is there any problem using a sealed roller bearing in it's place. Would this work??
 
You need to use the correct type needle brgs A roller brg will not take the necessary side loads
 
Seems to me that it should work with roller bearings. A swingarm pivot doesn't really take any side load to speak of. If there was, they'd have tapered bearings. Any load will end up being a radial input on the bearings on one side or the other. I don't think that ball bearings would be good though. Just make sure the tolerances are as tight as possible.

Some pics would be nice too :D
 
That's what I thought too Marcello. To my way of thinking, the sealed unit would be much easier to find & install as long as it would safely work.
