Bollweevil Posted July 20, 2007 Share Posted July 20, 2007 I'll try to call a spring shop in Chattanooga Monday. You might consider an upgrade to the later trunnion assembly's. They are a little pricey, but you don't have to change the bushings every time you turn around. Down time is a major consideration for myself. Of course it is the middle of the summer up here, and our busy season. I'll let you know what I find, James Quote Link to comment https://www.bigmacktrucks.com/topic/2675-trunnion-bush-part-numbers/#findComment-13053 Share on other sites More sharing options...

terry Posted July 21, 2007 Share Posted July 21, 2007 thanks terry,how do you cut them just in a drop saw?thanks again It is hard to use one of them they tend to squeeze down, i mark a circle all way around with a pen. then drill about a 3/16 hole about 2 inches apart all the way around, then cut hole to hole with a hacksaw, i have done alot this way.
