New Oil Dipstick from Norton Factory UK


Hello , This is the NEW oil dipstick from Norton Factory UK . Many thanks to Richard Pearce (BlightyBrti) for sending this information. The stick measures 150mm from the bottom of the threaded cap to the bottom of the stick. I have ordered this stick and when I get it I will have the original high mark cut in for my use , then put it into service . Looks better than the bolt I used for testing earlier hey ???? Long Live Norton ! Thanks again Richard !
 
Remind me once more about what is wrong with the original dipstick? :? I need to measure mine (late 2015) to see how it compares.
 
Hello Contours , There are some members on this forum who are tired of this topic. I am not however. So I will keep it short and concise. When the 961 oil tank is overfilled , it will push/spill oil back to the back of the head where the oil tank vent pipe goes. Then it is made available to flow back down the push rod tunnels to return to the sump for pumping back to the tank. BUT , that oil is also made more available to escape through the valve cover breather banjo and into the air box where it will need to be drained periodically. SO , the longer , re-marked stick lowers the oil level in the tank so it doesn't as readily get pushed/spilled out of the tank breather and ultimately there is less oil coming out of the rocker breather banjo and into the air box.

For most folks this is enough , but I will continue . The Norton Factory having realized this have developed a different breather system . You have seen it already I am sure. The most tell tale sign is the oil/air separator box in the breather pipe going from the crankcase to the air box. This update requires the fitting of oil feed valve and return line check valves , screen filters , rocker cover banjos blocked and the oil/air separator installed. When the kit is fitted as directed by the factory , periodic draining of the air box oil is virtually eliminated .

The short answer is YOU DON'T NEED THE NEW DIP STICK. I want one though .

Ha ha - well, that's what I was thinking since I've already adjusted my procedure for filling the oil tank after a change. In addition, the oil I find in my air box is manageable (though I don't understand why).
 
I like the new textured stick. Bet that's easier to read. I no longer get oil in my air box and I've lost maybe 2mm level of oil on the stick in the past 2700 miles. My level is dead center of the two marks. All the venting and new upgraded valve covers really have seemed to work wonders. So yea. What TonyA said.
 
Well, I finally measured my oil dipstick. It is the older/original variety measuring about 110mm from the bottom of the threads. I think I would like the newer version if it's that much easier to read. To justify the shipping charge I need add something else to the order. What else from Norton can't we live without? 8)

Maybe extra rubbers for the cush drive? :D
:p

My BST rear wheel is due to arrive this afternoon. I plan on writing a final summary of the experience sometime later. After I've ridden my 961 for the first time since June 14th. :roll:
 
All new bikes come with the longer dip stick and have the new crankcase breather. If you have access to TSB 14, it calls out that the amount of oil should be 1.5 liters vice the original 2.2 liters. With the shorter dip stick you would never see the oil when checking . The longer dip stick should show oil about midway in the serrated portion of the stick when the bike is properly serviced with 1.5 liters during a routine oil change. This assumes of course that you have the breather kit installed.

Hi there

TSB -00014
Date 20-08-2015

Item 60 on the TSB-14 states :

Put 2.3 ltr of oil into the tank ( 2 ltr first and allow to settle then 0.3 to stop airlocks)

Are there different versions ?
Where does 1.5 litres of oil come from?


cheers

How does one get access to the TSBs? Are these readily available from the factory?

PS - there are three dipstick lengths, long, medium and short. Mine is medium so I should see the 1.5 litre level against the low mark based on your info.
 
Contact your dealer they have access to them. It is essentially spelled out in TSB 14 which is the TSB that addresses the crankcase breather modifications. It clearly spells out no more than 1.5 liters of oil.
 
Hi,
Do you still have to run the engine to warm the oil and then wait a few minutes before checking the level with this new longer dipstick?
Cheers

I spoke with kev via email and he said 1.5L of oil is all that is needed. I don't agree with this small capacity of oil.

byjefsm,

The service bulletin 14 that my dealer pulled down from the Norton service site is dated: 20/8/2015
Clearly states 2.3 liters.
With my breather kit installed, and 2.3 liters of oil, after running the bike, the oil line is in the middle of the knurled area of new dipstick.

Is your bulletin dated after 20/8/2015?

Kev is correct. If your bike has the breather kit its 1.5 liters... Richards oil change instruction needs to be updated to reflect this factory change.
 
The newest service bulletin is dated 14/7/16 it clearly states as noted below 1.5 liters.


79. Once all stages above are completed refill the oil, as below: From a fully drained engine ONLY
including oil tank + sump
• Put 1.5L of oil into the oil tank
• Oil spec: Silkolene Super4 SAE 10W-40 Semi-Synthetic
I hope this clears up this issue.
 
Interesting. Less oil required after the breather kit installation? Even with the added volume of the check valve and extra tubing. So where does the extra oil go without the breather kit? To the bottom of the crankcase when the bike is idle for so many days? And then out through the airbox when it is started up again? That's weird because I carefully added 2.2L on my last oil change and have not had more than 5ml captured in the bottle after 200 miles. Then again, maybe after it has sat for 10 weeks I will see a significant amount once I start 'er up again. :?:
 
I believe this problem is similar to the issue that owners of classic Nortons have experienced for years.
The oil lines from the oil tank and oil cooler connect to the housing of the external oil pump.
Normally the tolerances of the internal pump vanes are pretty tight, and can hold back the oil within the pump housing when the engine is not running.
But there is seepage especially when the oil is hot, and over long periods between operations.
Drip, drip, drip and over time much of the sump fills with oil seeping through the pump mechanism itself.
I think the new press-in oil pump check valve in the breather kit is designed to stop this seepage, or at least greatly reduce it.
If the oil doesn’t drain into the sump, the dip stick readings will be more consistent.

This is the inherent problem of a dry sump engine, and why most manufacturers use wet sump design instead these days.
