off with the oil cooler

[Eveready1100]

I just finished a cover to cover search through both of these





and can't get over the fact that there's no photos or diagrams to cover the oil cooler and adapter like in Brians post.
The Cycleserv was printed in Australia in 78 so there's no reason why it didn't rate mentioning as it covers the bike that was marketed here.
The Clymer was printed in the US so it's probably understandable why it isn't covered, though there is a one paragraph description of the cooler ( not the adapter housing) in the supplement at the back of the manual.

Which reopens another riddle about my bike which is a 3H3 Special (Yank market according to all the numbers)  and it's got an oil cooler fitted?

Hey Jeff,
There seems to be a strong argument against the cooler by the US guys.

I'm confident it'll be ok

G,day Jeff,
I have considered many of the things you mentioned, particularly clearances. As we all know todays bikes with liquid cooling run much tighter tolerances than the machines from the XS era.
If you consider that parts of the US are equal or more extreme in summer temps than here and yamaha released the XS in that country without the cooler (on some models) I reckon the risk of engine damage is minimal.
The modification is definitely not permanent as it can all be bolted straight back on.
My day job is condition monitoring of industrial equipment which gives me access to some appropriate bits of gear like infra red temp guns and oil analysi labs.
So I'm thinking I'll do a before and after temp survey on the filter housing, sump pan and the oil line up to the head at the back of the motor. I'll try as best as possible to do the same run at the same ambient temp and post the results here.

Seasonally and of course dependant on where and in what country you live in "Air Cooled" engines wlil operate/perform differently throughout the year.Removing the oil cooler should be thought out carefully .Longevity of our ageing motors is what we all seek .Permanent removal of our coolers to fit an aftermarket exhaust? I for one would rather keep the cooler and look for, or have  one  made that fits with the cooler in place.If you live in a cooler climate.......maybe just cover up the cooler with a thin galvanized cover that is easily removable on those warmer days or if you get caught in city traffic or are in the mood to race the engine on a day run .Look at the vicosity of oil your using and change that for summer and winter if starting and short runs are your issue .Stress is also put on a motor if it is run too cold with too thick a viscosity of oil .I don t need to waffle on about what overheating of any engine will do to it.
Just some food for thought as to why you would want to do this and what benefits you expect to gain .Does it put you at risk to suffer later on due to this expected gain? (Leaking oil/engine gaskets/seals ,tolerances within the motor?)
Aside from the heat losses from the cooling fins on the barrels , the oil cooler is a worthwhile aid in this as well.
Everyones situation is different but i for one will be keeping mine in place. The positives outweigh the negatives in my opinion.

Gee, here I was about to go and see Mr Enzed to get a new LH pipe made for my cooler and everyone else is taking their coolers off!

The original LH pipe on my bike obviously failed or was damaged at some point and has been replaced by a length of standard rubber hose with a couple of hose clamps at each end.

it will be fair bet the manual uses an o/s model then

Goiing through the haynes book yesterday and studying the A3 size liftout for routine checks and adjustments I noticed the Bike drawing used on the liftout isnt fitted with a cooler.

I'm sourcing the various parts now for a first service in who knows how long and I'm gunna take the plunge and remove the cooler and adapter block.

Coming into NSW central tablelands winter I'm sure it'll be ok. -4 deg last night

That's it, in a nutshell, Steps.
Only snag is having enough oil with you at the time to do a refill after removing the leaky bits.

so like we were saying Ev, if there is a hic-cup with the cooler,, { a stone going thru it or such}

take the bottom assy off ,, take the extension bolt and the filter hose block off the motor and do it back up again

that there is some pretty cluey thinking from our 30 yr ago engineers

[Eveready1100]

They say a picture is worth a thousand words. Well, those say it all!
Thanks Brian for clarifying that for us. Now the options are clear.

I reckon that the bikes with oil coolers have still got the normal size oil filter bolt.  It's got an extension screwed onto the end of it so it looks longer.  here's the extension piece (No. 7 below)


So, no new parts needed, you'd just need to remove all the numbered parts in this pic...

[steptoe]

that'll be the easiest, most unmessiest  solution for you then  jonesy

[Eveready1100]

Mate, that valve is only to stop the oil in the cooler from draining back into the sump when you switch the motor off, so it's got some in the lines for when you start up again.
Remember, the oil cooler was an add-on that they fitted to the bikes for our market and plenty of guys over in the states are retro fitting oil coolers to their bikes using similar adapters and all they have to do to fit them is get the longer filter housing bolt to suit the assembly.
Shouldn't need any other mods at all.

I hadn't even thought of the section removal as an option,,, didn't realize it was one

what does the little releif valve in that section do tho,, is that only associated with that section,, and the oil cooler, or does it affect the whole motor
