    I am putting a 203 back together and I am wondering if It is ok to use blue RTV sealer on the adapter,
    input shaft housing,and the front output housing or if I should just get the gaskets does it matter???

    TIA

    I used high temp black rtv on mine but it leaked. The gasket in there now doesn't leak at all so I'd go with the gasket.

    I started with nothing and I still have most of that left! - <a target="_blank" href=http://24.55.50.76:81/k5/> Pictures</a>

    I have not worked on a 203 (ever) but I can tell you that a gasket is the only way to go. RTV can work if you do not put to much (most people do) or of course, put to little, but it will never last as long as a prefab gasket.

    Also, if you go with the gasket be sure to use a little RTF with it. This will give you a little room to breath if you fail to tighten the bolts within an acceptable torque tollerance (this also means to tight). Again, do not use to much as this will cause leaks, just BARELY enough to coat the surface of the gasket.

    Good Luck....
