R60/5 Oil Filter Housing question

[AnnapolisAirhead]

I went to change the oil filter on my '72 R60/5 Toaster and to my surprise, its different than my R100T. Both are non-oil cooler types, but when I removed the three 10mm cover plate bolts, I found a 17MM bolt holding an inner cover with two little nubs and a tube that the filter slides over.

Is this typical? The inner cover appears to keep the filter compressed and the outer cover plat is just another cover plate (it has the paper gasket). Anyway, after posting on a thread about oil filter parts, I'm questioning myself about the white o-ring now because it is noticably absent from my /5. Is this due to the inner cover plate?

You're right on all counts: No O-ring is used on either cover. The cap with the 10mm (17mm Hex) seals the cover to the housing and the gasket seals the outer cover. Exercise some caution when installing the inner cover- it can be trapped and cocked by the oil pan bolt which sometimes protrudes into the filter cavity. This gives the same results as the "$2000.00 O-ring".

Good advice, thanks. The old filter I pulled out was a straight one (this bike had been in a garage for 10 years). So the hinged ones will (gawd I hope) work with this arrangement??

There are two hinged filter designs - short and long. The short hinged filter, all together the same length of the one you took out will work. The long one will not!

Also - years ago the filters came with two rubber O rings and plain metal ends. Today, and for years they have come with rubber sealing rings built onto the ends of the filter.

So carefully look to see if an old O ring might still be stuck in the filter housing. If so - pull it out with a right angle pick.

Paul, you mean from inside the filter housing (e.g. in the engine block) furthest inside the engine? The large white o-ring on the other bike gets installed at the cover plate end (at least that's where I've been installing them).

In either case, I'll look.

Look at a "modern" filter with the black rubber seals on its ends. They used to be plain metal caps with a hole in them, and a separate O ring at the two locations where the rubber seals are now attached.

So - yes - I mean look into the filter canister all the way to its end where an O ring would seal the inner end of the filter. Lots of O rings got left there on older bikes. And once it is squished and leaks the oil doesn't flow through the filter fully any more.

Also - while on the topic - be sure the inner cover is on tight. A leak at this location causes low oil pressure, but the oil drains back into the sump so you don't see a leak.

All is clear in the housing and both rubber bits were on the filter. Thanks Paul for the help and another tip to avoid a big problem. Hope to catch you are the Super Tech.
