Oil cooler

I've got a spare oil cooler if anyone needs one: bought it of Malcolm a couple of years back but didn't need it: good condition.

For the rivet counters, here is the original oil cooler on the bike and a spare I have, supposedly for the same model. Fittings and size are about the same but the ends are different, original to my bike has rounded corners, spare has squared corners and a seam running around the edge. Different suppliers ???

Chappo,
What number (-ish if you're worried about privacy) is your RGS?  I just had a look at Christiane's SFC-ificated RGS and it has the late 180 cooler as per what you took off your bike.  Hers is #188x so a pretty early one (82?).  Of course it went through a  few owners so anything is possible but it looks like that might have been original.  Both my other 120's are 250x + and both have the later one.
Rivet counters of the world rejoice.
Cheers

Hi Steve, the number is 22 something. I can't remember for sure what the last two are, and I'm not home to look. The rego papers say it is an '84 model.

Hi Steve,
FWIW, my RGS #169* also has the late 180 style cooler. I've owned the bike for 25+ years and I'm confident that it's original kit.

I'll get back to rejoicing with the rivets..... :-*

This is the original one from my RGS. It is clogged up with bits of front cam chain guide.

Chappo..did the bird cage oil screen in the engine sump miss filtering out the chain guide bits??

I have just found the oil flow diagram for a triple (supplied by Red).
It looks like the oil filter actually seems to be a suction strainer.
I am surprised the lumps of plastic got through.

I could get shot down in flames with this, but the filter (strainer) could be AFTER the cooler.

I'd get ready to bale out Simon. :D

Hi Rusty, my filter doesn't have wire mesh, it is just a can with holes in it, holes you can poke a pencil through. I suppose I should do something about it one day. When I first saw it, I wondered what the Hell it was, 'cause it ain't no filter, that's for sure.

When I first saw a photo of one with wire mesh, I thought, wow, a fancy man's filter, I wouldn't mind one of those! That's when I realised mine was missing something, I'm pretty quick like that.

Mine is nothing like this one, it is about two thirds the height, and where this one has the wire mesh, mine is solid metal with, as I said, holes drilled in it. Next time I have the exhaust off, I'll take it out and take a photo.

You night be able to dissolve those bits out of the cooler with a suitable solvent. Try acetone.

Thanks Cam, I didn't throw it out because I thought there may be way to unblock it. I'll give this a go.
I have some hydrochloric acid, I wonder if this would be worth a try? It might eat into the alloy though, I don't know much about hydrochloric acid, I bought it from a pool place to clean oil stains from the concrete floor. It did this job well, and I've got some left over.

we have a few spare ones in stock Chappo if you want a proper one for your RGS, they are slightly different to the one you showed a picture of

Rusty,

Looks like an original '74 factory chromed 3C cooler with horn mountings. Chrome made them prone to cracking? and almost impossible to repair.

jacko.

:o  Fuck, NO!  Don't use hydrochloric acid. It'll fizz like mad and produce copious amounts of hydrogen gas, while eating the oil cooler and leaving the bits of plastic un-touched. You could end up with an explosion in the confied space of an oil cooler innards.

Check out this video. It takes a while to get going, but really starts to fizz once the acid gets through the oxide layer.


Don't use caustic soda either - much the same result.

You need a plastic solvent that won't hurt aluminium. Choice of solvent depends on the type of plastic. Acetone or ether are worth a try. Between them they'll dissolve pretty much any plastic except PTFE (Teflon). If the tensioner slipper is made from PTFE (which is quite possible given the application) the only thing that'll dissolve that stuff is benzene.

Try some solvents on a piece of the plastic.
