So does that make it an RV?

my last camp was an adjustable shower curtain, an air mattress and a tarp over my pickup box... RV luxury to many I'm sure  ;D

I was not quite sure about the exact design of the squish plate for the oil cooler, so I spent today making up a practice part out of MDF.
Happy with the final result and it all bolts up tight! Just got to get a 3mm end mill to machine the O ring groove, then I will be set to go.

Now thats something! Wish i could do things like that. My adapter is slightly thinner i think. Found a retailer in sweden who still had a stock of lockhart aftermarket coolers for xs750's since the 70's. Around 150$ for a complete kit, but your way is awesomer!

Is there a reason you decided against the stock 850 oil cooler plate?
I don't think it's a whore shot until you start posting pics of it on other people's build threads.
So it's all good.   8)

If I could have found an XS850 oil cooler, either OEM or aftermarket I would have bought it. But you have to get all the parts, including squish plate and threaded adapter socket. XS1100 and XJ650 are the correct size but have the outlets exiting out the side rather than front and foul the engine mounts. After 2 years of searching without luck, I finally gave up and bought a Ebay Chinese 7 row AN8 Universal oil cooler kit. I knew at the time that the sandwich plate in the kit would not fit, so that's why I am making a new plate. Now if you have a spare XS850 plate & socket in the shed, let me know, as they are a more elegant solution!!!
Confirmed a few more measurements today and I have been able to reduce the thickness from 32mm to 28mm. How thick are the genuine plates?
Photos are of all the features that need to be considered when making the plate.
Cheers

They can still apparently be bought from sweden.
Edit: this one was even cheaper, no thermostat.  And it looks like ports are facing the right way.

Thanks Dave
The cost came to AU$390, so I passed on it and will stick with shed time!!!!!! Thank you for your help though.
Lucky day - I was able to spend most of it in the shed - next weekend is a write off!!
Morning was oil cooler and afternoon was the start of the headers. Cut all the 90o bends to length and flanged them with the tool I made and a ball peen hammer. Very happy with the result. I also made up some new header clamps out of the off cuts.
The photos are the sequence of forming.
Cheers
Tim
