I'm a fairly handy guy (I work on 4 stroke small engines regularly, and I've put a new clutch in my car) but I'm concerned about putting new crank seals in my 066. I have a manual, and it looks like I would need a flywheel puller, a seal puller, and a tool to put the seal back in. I may have a puller for the flywheel that will work (looks like like one for a bike crank), or I can buy one, but I'm wondering if I need the specialized seal tools to remove/insert those. Can I pry them out with a dental pick or the like? Can I press them in with a pipe or socket? Is the depth to push them in so critical that I would need the special tool? I'm sure some of you have done this. By the way... I'm considering doing this as I think I have a small leak (I cannot kill the engine by backing the idle screw all the way off) and it seems like good preventative maintenance. Yes, there may be a leak elsewhere, that would be my next adventure. Any advice you can offer would be appreciated. If there is somebody in the Milwaukee Wisconsin area that would rent the tools to me, that would be awesome! If this task requires that I purchase all sorts of specialized tools, I will probably support the American economy by paying $ to my fellow American worker at the Stihl dealer. If this task can be done effectively with few specialized tools, I will probably support MY economy, and keep my checkbook in the black while training an American worker in a new skill (me). As always, thanks to the collective wisdom of AS, and I hope to continue to contribute as I can.
