Title: Oil Filter Canister
Post by: TomJ on November 07, 2011, 07:53:06 AM

Got the oil filter canister cleaned up and  painted, just need to put on the decals and it's ready to mount.  One thing I cannot figure out though is exactly how the oil is suppost to drain out the bottom.  I can't see around the little bracket on the center shaft (the one that supports the filter canister) to see if there are suppost to be drain holes in the center shaft to let the oil flow out the bottom.  Don't know if mine are plugged or if I have the whole thing figured wrong, nothing I put in the canister drains out (I washed it out with gas to clean the slug out of the bottom of the canister, when I poured gas in it just pooled in the bottom). I'm at a loss, how is this thing suppost to work? Does the oil drain out the bottom or is there some other principle I'm not seeing?

There is a tiny hole it the stand pipe that goes up the center of the canister.  It is only about a 32nd of an inch in diameter and is near the top of the pipe.  If you didn't fill the canister almost full, nothing would run out the bottom.

There it is!!!  I thought I'd looked everywhere but I missed that, boy I just had it in my mind that the drain would be bigger.  The heavy rubber washer thats on the center shaft, does that go above the filter or does the filter rest on it?

Sit on top hole. May be the hole is dirty.

So more questions, the filter canister has rubber grommets that obviously seal it on the shaft, there was already a heavy rubber grommet on the shaft, was that from the last filter or is that suppost to be there?  If it is suppost to be there, does it go above or below the filter? Also I got two gaskets with the canister, one is a flat gasket that looks like it was made to fit into the cap but the other is a rubber o-ring type that is too big to fit inside the canister and too big to fit into the rim of the cap, where the heck does that one go???

Thanks
Tom

Great questions - as I''m changing my filter as well.

the new filter is a fram c3p - the old filter(labeled "for farm use only") was much smaller
and not as snug against the wall as the c3p.

Since the Fram C3P has a rubber washer built in - should I remove the
heavy rubber washer on the bottom of the shaft?

Thanks for the input -
