    Ok I messed up good this time, I was replacing my tailshaft on my NP-205 from a slip yoke to a fixed. Well it started to rain so of course I started to hurry. well it seems on of the bolts on the tail shaft was cross threaded and I kept on truning, till the bolt was striped. So now I need to know if its fixable. And how do I fix it? Thanks Jesse

    A helicoil will fix it good as new.

    Not trying to sound to stupid but I thought helicoil's could olny be used in application's that had bottoms. this stripped hole is open on both ends. Again I am just wondering. Also the proper way to install a helicoil if I remember correctly you need a special tool. Thanks Jesse

    Use a thread sert. Not sure why anyone uses helicoils anymore with thread-serts available. (no offense) You drill out the hole so you can tap it out to the next size, tap the hole with a STANDARD (not goofy helicoil) tap, then thread the thread-sert in. The ones I pick up at the local non-chain hardware store for about $3 already have loc-tite on them, (to hold the thread sert in place) and I have used them on aluminum thermostat housing bolts that have stripped out, and they haven't leaked in over 4 years

    Thread-serts or weld and re-tap. If you can weld, that is my preferred method, but if not a thread-sert will work just fine. The tail-housings don't have a ton of pull put on them, plus the other bolts should hold it well enough that it won't over stress that one bolt.
