Bushing Press (Portable & Home-made) Input Sought
I came across this detailed description of pressing bushings
out of suspension control arms using sockets, high strength bolts and nuts, washers, and muscle: http://www.maxcooper.com/rx7/how-to/...lls/index.html Evidently, sometimes the bolt breaks during this process. I ran some numbers to get an idea of how likely this might be, and I'm seeing around a factor of safety of 1.5 to 2 (assuming about four to six tons of force is placed on a roughly 3/8-inch diameter, grade 8 bolt). People say a 2-ton shop press isn't enough; a 12-ton should be plenty. Hence I'm guesstimating six tons of force on the bolt should be enough. Has anyone tried this method on his/her Honda's control arm bushings? Please report if you have. I am particularly interested in the socket sizes used. If I can get the right sizes the first time, that would be great. Otherwise, it's not all that convenient to run (um, bicycle) back and forth between the several stores I would use for sockets while my car is out of commission. I might also call around to some of the salvage yards and see if they have a bent control arm I could buy very cheaply. Then I could drive around town with this "spare" control arm, get the dimensions of the "home-made press" right, and practice. My ball joint separator is now on order via Ebay: $35 total for the two-stage version to which Ryan posted a link earlier (JTC Auto tools, #1727). This one was available via bidding as opposed to "buy it now," so it seems I saved a few bucks. I do think my new front springs have eliminated some mild clunkiness (when going over bumps) I heard before. TIA for helping with my project. |
