• LawnSite Homepage Upgrade

    Hello again LawnSite community,

    I wanted to post a quick note to let you know that the homepage of LawnSite will experience a major upgrade later this week. We’re always looking for ways to improve our users’ experience on the site, and felt that this upgrade was needed and long overdue..

    With this upgrade, you’ll now see the top trending posts as soon as you visit LawnSite, and these will be updated throughout the day. You can also easily access videos and photos. As always, we encourage you to include videos and photos in your own posts to share with your fellow LawnSite users.

    Be assured that all of the forums, content and data that you’ve been accustomed to will remain intact, as will all current site features. You’ll also be able to easily access the full list of forums directly from our new homepage.

    We’re excited to bring you this change, and look forward to hearing your feedback.

    Thanks, LawnSite Team

Damper on 78 3/4 ton

I have a 78 3/4 chevy and the damper seems to be making lots of noise. I am not sure if it is out of balance or what? It makes like a "swishing" noise, everytime it does a full circle? Is there any type of adjustment I should be looking at? Cleaning it or having it machined? Come to think of it... maybe that is why my front seal is leaking (I'll leave that one for the next message). Any body out there have this problem it is really a noticable noise once you hear it you can recognize it.

if its doing anything its not supposed to, replace it :) if its a sb400 or 454, then you can really have some problems with it spinning on itself..(counterweighted) but if its a regular internally balanced motor (ie NOT a sb400 or 454) then your timing marks will be off, and theres always the possibility of the outer ring coming off and doing who knows what to anything thats in its way. As for the noise, dont know.. but I seriously suggest you get it replaced asap.

might as well do that front seal while you are at it :)
