Topic: oil pan installation

[scknight]

My current oil pan has stripped threads for the drain plug and is cracked and leaking. I am planning on replacing the pan. I have a new pan and gasket and just had a quick question about reinstallation. Is there anything I need to put on the gasket? Or do I just stick the gasket on the pan and install it and tighten it up. Seems like a simple thing but I just want to make sure I do it right so that I don't have to do it again. Thanks!

I replaced mine as part of "The Great Ressurection." I didn't put anything on the gasket and it has been fine. Remember the bolt locations, they are of differing lengths because the thickness varies.

And don't overtorque...

I just put a little oil on it (like an oil filter gasket) just to hold it in place. I cross-tightened at least twice to draw it down and not overtighten.

Does anyone know what the oil pan bolts should be torqued to? Is it the same for all of them? Or different because they're different lengths? Thanks.

If I were you I would simply use a small wrench and tighten by "feel", erring on the safe side. If it leaks oil you can always give it another quarter turn.

FWIW, I found my CB350 lower crankcase -no oil pan- with a near-to-stripped threads on the drain plug hole. It seemed to tighten well, but I didn't want to run the risk of replacing it in two years so I bought a new one. I plan to be extremely cautious when tightening the drain plug.


And the same goes with my 750. You surely know that emptying the oil tank is a pain in the back because of the spills. I was planning about emptying it next time with an external oil pump instead of draining it. What do you think about it?
