oilfilter gasket problems

[114015]

Dear Pagoda community,

Today, I am seeking help & advice from you.

The other day I wanted to perform a very easy job that Joe Alexander recommended already years ago during PUB:
Changing the gaskets within the oilfilter housing.

According to the EPC there are three rubber gaskes (plus the large canister ring which is always included in the oil filter replacement kit 000 180 0009; I am not referring to that one).

These are

1) A000 180 3380 upper gasket (part no.  219 in the parts figure) - No problem at all to replace that one
2) A000 180 3280 small gasket (part no. 240) - Oops? Where does that one belong to? It doesn't make sense in my eyes.
3) A000 180 1780 large lower gasket (part no. 233 in the parts figure)

I am referring to this last gasket, the lower one (part no. 233).

How do I replace that one? It appears to be fixed by a stepped shim at the bottom of the oil filter canister - see my picture with the screw driver. The tip points towards this metal shim.

Please, how do I get that shim off without destroying anything?? The shim is not listed in the parts list.
I would love to replace the completely hardened and brittle old ring.

Pictures tell us more than some 1000 words.


How do I do this? Please advice.

Thanks a lot in advance

Hi Achim,
take a look at the annotated picture that I posted here: http://www.sl113.org/forums/index.php?topic=2589.msg39395#msg39395
Your number 240 is my number 40, and your number 233 is my number 39. You should be able to see the location in the drawing., and you can read Joe's comment about 240/40.
Cheers!

Hi Achim,

Hope you are doing well. The sheet metal part is pressed on and is sometimes deformed during removal, but it is easy to straighten out. I set the canister up-side down on the work bench then use the blunt punch through the bolt hole. You can also modify the punch to work better by grinding a notch in the side. Jon Bernardi has a post with some pictures of this process here somewhere.

Dear Gentlemen,

Yes,
thanks a lot - I found it (and started to understand it).

That's how I started to address this problem, with a punch through the hole with the canister upside down.
I became scared when I realized that the sheet metal part bent.
I think I must become braver!

Thanks a lot again - I'll give it a try

Achim,

Yes, the first time I tried this I chickened out. I got a used canister to practice with to just be sure. As Joe typed, taking a blunt punch, and filing a notch in the side, makes it much easier to get a good bit of force on the little metal part. I have helped several friends do this, and yes, it takes a bit of courage, but just work at it and the little thing will pop right out. Then if it is deformed a bit, you can just tap with a small hammer/punch to get it back into shape. The overall shape at the top is not critical, it is the bottom and the gaskets that hold everything in place.
