Re: 394 Bar stud problem?

501 81 57-01 is the correct bar bolt part number for all versions of the 394 including the EPA version. When replacing bar bolts some people just put a nut on the damaged stud and beat it out with a hammer without heat. I suppose this may work one time but over time it will pull enough metal off the inner case mounting flange, not leaving enough purchase to keep the stud in place.

What Shep said in the previous post will work, I have had to do it several times. If I am doing a rebuild that requires splitting the cases, I tap out the studs at the same time I am heating the case to remove old bearings, and tap in new studs when I heat the cases to install new crank bearings. If the saw has seen enough wood to need new bottom end bearings then what is a couple of bucks for new bar studs. I know, some folks would rather put the bearings on the crank and force it into the case but this is not how Husqvarna taught me to do it.
