There are two oil screens in the KTM RFS engine (different from and in addition to the oil filters) - I have a 520 SX and the 13mm side screen bolt is seized.
I was hoping someone might be able to help me out with getting it out.
I've tried a breaker bar, trying to get it out with the engine hot, using the flash freeze / penetrating oil that auto zone sells, and a handheld impact driver.
I bought some of those bolt extractors and have tried using those with the impact driver when the 6 sided socket I was using started to slip off the head of the bolt. I've pretty much given up trying to save the bolt and just need to get it out at this point.
None of that has worked so far. I have googled the problem and it seems to be fairly common. I'm a little nervous b/c some people have cracked their cases trying to fix the same problem.
I also saw suggestions to heat up the bolt with a torch and let it cool...I've also ordered some "blaster" penetrating catalyst which is supposed to work pretty well. I'm a little hesitant to take a propane or mapp gas torch to my engine case...
I'm thinking that trying to hit it with a pneumatic impact driver might be the next step.
I don't have one, nor do I have access to compressed air. Is there anybody in the Boston Metro West area that has one that I could use? I figure I could just swing by with the bike in my trailer and see if that works.
Open to any other ideas....
