Need to replace Front Crankcase Seal. Need to get to it first, naturally.
Got as far as removing the outer-half of the vibration dampener (two sided assembly with the rubber isolators). There are (4) 5/16 Flat-Head, Hex screws connecting the rear half of this assembly to the main pulley (in this case, a dual pulley). Got two out after some effort. The next one: thought it was loosening, but I was rounding the hole. The next one went similarly, even though I tried heating the crap out of it. The JD manual notes that Thread-Lock was supposed to be used, but I saw nothing on the two that did come out. I was using an impact-rated 5/16 Hex socket which appears intact.
Advice on modern Screw Extractors would be welcome. I have obtained a couple of possible options, but they seem to be pretty cheap, and many people note the tools snapping, possibly leaving hardened tool bits embedded inside the screw (making things worse). I have been spraying PBlaster on the screws twice a day or the past few days while waiting for some other extractors.
One screw is stripped more than the other. I was able to feel something of a bite with one remover, but now I am paranoid to actually do it. A set of Irwin Industrial extractors is on the way.
Tips on removing these? I could really use some advice. I was considering sacrificing the rear-half of the isolator casing if needed.
