Chainsaw Repair

029 and need to replace the rear side plate bolt as the thread is buggered-does this stud just wind out?

 Just to make sure we are on the same page. Are we talking about bar studs?

I have never removed this style before. But from how I have removed others in the past. I used 2 THIN nuts together to remove studs. Tightening one against the other. THIN because of the limited area you have to work with on those.

I have read you need to heat the bar stud on the 029 style to loosen the adhesive glue they use on the bar studs.  Using a propane type heat torch most homeowner have.

Here is another guy removing stud.

  I just thought I would mention how I just did this on an 029. I tried the double bar nut trick but it didn't work for me, probably because there's not enough thread on the stud to fully screw the second nut on and I didn't want to risk stripping the threads.

So what I did was first to take off the chain tensioner and little aluminum chain catcher under the stud (for reasons you will understand in a second).  Then I heated up the bar stud with my propane brazing torch (like you use to sweat copper pipe).  The repair manual says to heat it up to remove it, I assume to soften the thread adhesive.  So I did this for 10 or 15 seconds or so.  Finally, I used a pipe wrench to grab just the shoulder of the stud, which extends from the plastic housing by only about 1/8" inch.  If you grab the stud itself you'll screw up the threads as I found out quickly with my vice grips.  The pipe wrench must have sharp jaws for this to work, and it actually does have to bite into the stud metal a bit to get it turning.  But surprisingly I was able to get the darn thing out such that the stud could be reused.   The reason for removing the chain tensioner and catcher was to allow more of a turning radius for the wrench.  Even so, I probably only had about 135degrees to turn each time, and some of that was used as the pipe wrench jaw started to grip.

Anyway, that's one poor man's way to do it if you don't have a stud remover

I wouldn't be surprised if in fact the studs were inserted using red Loctite  which does require some heat to remove .Pretty tough stuff .

To bad the thread are buggered up

There pretty easy to get out with two bar nuts

Just put a little tension on it (both nuts) and a little tap from a hammer usually loosen them

There is a utube vid showing how to remove them just can't find it right now
