I tried searching this forum for an answer, but came up short. Does anyone know the exact size of the 4 copper crush washers used with the oil pump banjo bolts? I am guessing M14. I want to purchase several sets for my current and future oil changes. Richard, I know your manual explains a way to recycle the originals, but I don't even own a torch. :roll:

Thanks in advance!
 
I purchased mine from the dealer. I don't remember them being overly expensive , I bought 10 or 12 of them from MCC. I will look and let you know the cost. Also I have reused mine 3 times with no issues. So if you can get say 4 oil changes out of 1 set then the dealer price is ok.
 
Oh - I assumed what Richard's manual said about replacing them was set in stone. I have reused them in the past, but didn't want to mess it up this time if it was risky. Thanks for the info. I was hoping someone knew the size, as in ID and OD.
 
Seriously, it would be cheaper and less wasteful to buy a propane torch. You can reuse them as many times as you want as long as they are not broken. It's only soft metal. It's just a seal. Don't waste your time buying multiple sets of copper washers. Seriously!!!! Buy one spare set in case you loose them. RE-USE them.... the proper way is to do this. Do not over tighten, if they leak, tighten slightly more. The idea is the copper is soft, so it will conform to take up the space required to make a seal.

Ask anyone with a two-stroke, vespa guys, dirt bike guys, snowmobile guys -- ask around how many times they have pulled the head off to de-coke (get the carbon off the piston and inside of head. Almost any one who races does this many, many, many, times a year!!!!! ALL USE REUSE THE SAME copper head gasket until it breaks >> which is usually an accident and not from doing it too many times. DO NOT BE AFRAID TO REUSE IT!!!! Dealers only want to sell you more product. WASTE OF MONEY!!!!

HEAT THEM UP GLOWING RED and drop in water. DONE!!! I would not lead you wrong!!! ask any mechanic.

I hope this rant changes your mind... :mrgreen:

I know you wouldn't lead me/us wrong, Richard. Just saying I have very little space and even less time to deal with it properly at the moment. Having a few extra sets wouldn't hurt. I think I will just remove the originals, measure the OD, ID and thickness, and then re-use them for expediency while I wait for new ones. It's not getting any warmer around here. :lol: Your mornings must be mighty chilly by this time of year too, eh?.
 
Hello Contours and Richard , I have the part number and the price I paid for the copper crush washers. I did order 12 of them by the way , which will last me many years . I am going on 4 oil changes on the originals and they are still working good for me.

Norton Part Number 9400035 washer , copper price $1.99 ea. ID 14.23mm , OD 19.80mm , 1.85mm thick

So $24 bucks for a dozen copper washers , not real cheap but they are nice and thick and will last a long time .

Is everybody happy now ? Now lets get out and Ride em !

Thanks Tony.

Last week it was +28c but this week Mornings are a lot colder indeed. Bike loves it tho. I'll ride to work if it is +4c or warmer with zero %chance of rain. That's my limit for the gear and distance I commute to work with. I've ridden colder and almost always have regretted it so My rule is +4c.

On the Norton the tires are questionable under 10deg c. I was told they loose a lot of grip under +10c so I take it really easy. This week has been +13c morning and +20c afternoon. So def. rideable weather.

Under +10c I have a joggers balacalava, winter bike gloves, a t-shirt, a long sleeve shirt, a sweater and my jacket. My Robinson Jacket is great at blocking wind when needed. And with Layers I can use it from +4c to +30c But I probably push it because I have it open at the top and my cuffs open too. Without wind, +27c would be max for that jacket. But it's the only Jacket I have now.

From +10c - +15c I do not wear the balacalava or winter gloves just regular gloves. Actually Roland Sands Barfly is what I use from +10c up to about +34c.

Been riding for a while so I have it down pat.. No grip or arse heaters here..

Perfect! Thanks much, Tony. Although I will definitely beat that price - $1.99 each - yikes!!
 
Richard and Britfan, you guys are wicked hardy. My cut off these days is about 48° F. :oops: It's my hands that can't take it.

I would also be interested buying some , if they are good match and quality.
 
I might catch shit too but in the metal industry it is known that those countries don't use the purest blends. A lot of coppers from that area contain iron. Which will mean if it was a water pipe there will eventually be pin holes. But We are using it for an oil seal so you will be fine. JUST SAYING.

Here's my new plan, Richard. Since the Norton 961 workshop manual doesn't even mention removing the hoses to the oil pump when changing the oil, I am going to bypass that part of the procedure just this once and very carefully measure the oil I put in maybe 100 ml shy of what is required. Then I will check the oil level to see if I overfilled it or not.

My goal is to get this oil change past me and go riding tomorrow while no rain is predicted. Then on Sunday I'm going to pull that ECU and prepare it to be shipped somewhere for a re-map. That ordeal might easily eat up 2 weeks and then all I've got left is sunny weekends in October. Just feeling pressed for time, ya know? :wink:
 
You are really over thinking it. Borrow a torch from a neighbour. Or buy one. In canada a plumbers propane torch is available at every hardware store for under $15cdn. You need to crack those banjos to drain the oil cooler. Sorry to say it but I don't trust the manual a whole lot. Many many mistakes. There are a few revisions and even the latest has issues. Hence why I started making my own. Its your bike to do what you please and please know I'm not poking fun at you. I just want you to know its a lot easier than you think and want you to do it properly. Once you do it once you will see how much you over thought it. I'm only trying to help you out. Do it right and I promise you will thank yourself you did it right.
 
Okay, okay - I believe you. I'm not used to not trusting a workshop manual, that's all. You make an excellent point. I didn't consider the oil cooler. Alright, I will rethink my plan. Thanks, man.

Get a throttle lock and ride with your hands in your pockets. :mrgreen:
 
Been meaning to post this for a while now. This is my 7 year old changing my oil. He followed every step in my manual. Which is cool because he proved to me that it's easy to understand which is my goal...... and I taught him how to re-use the washers.. :mrgreen: I think this was his favorite part.
