    I'm putting my 205 and sm465 together, just wondering if those old chunky gaskets are needed or can I just use sealant or should I use both????

    I don't know the answer so I will just make a smart alec remark so you know the post is not getting ignored..

    Weld them together and eliminate the gaskets completely.

    I'd just use some RTV. Works for me. Just remember to NEVER use it near an auto tranny. It can and will make it fail. I know this isnt you case, but wanted to throw it out there.

    I just did this, first time I just did the gaskets filled them up with gear oil and everything started to leak by the next day. Replace the gaskets again but used this crap [​IMG] and several gaskets are still leaking. I am just going to let it leak. But next time I will use gaskets and some black rtv silicone.

    I like to use the gaskets with a thin coat of RTV on both sides. Just the gaskets is almost guaranteed to leak. Just the RTV is OK, but the clearances are designed to have the thickness of a gasket in there. Also make sure that the surfaces are clean and free of all old gasket material, grease and oil. I like to wipe 'em down good with laquer thinner since it will cut anything, and it evaporates fast and clean.
