Well folks , I have small issue with chain rubbing against primary cover , lots of movement sideways on the chain I am going to buy new chain what do ye recommend I think the one is on it is very heavy duty and no need for it , as for rubbing against primary I think it’s only started last couple hundred miles, I read all posts on it and think a narrow chain will do it, sprockets are perfect , I don’t really want to pull primary off ,

IWIS/JWIS M106SL is narrower (but still 5/8" x 3/8") and will fit. AN will recommend the IWIS Elite.

I have been buying my chains from an industrial supplier not a motorcycle shop the chain I have been getting is DID 10B which is 5/8x3/8.

Is it a narrow chain ?
 
L.A.B. said:
Yes, if you buy Elite from Andover then it will fit but if you buy "Elite" from elsewhere then it might not.




"10B" is the narrow 5/8" x 3/8" chain.
JWIS M106SL and AN Elite are 10B.

perfect I will buy if tomorrow thanks again for the help mate
 
update folks , i bought and fittedthe chain off andover and it fits perfect and does not rub off primary cover anymore , i did however have to cut one link off it as it was too long , still thanks again i am very happy with it smooth out
 
In case anyone's unclear as to the difference between 5/8" pitch chains certified as ISO10190 & 10B1, I thought people might appreciate some technical details for both.
The chains originally fitted to our classics was essentially to the spec of 10B-1. In old Renold codes that would have been 110054 for 1/4" width & 110056 for 3/8" width.
These chains were & are manufactured to ISO606, a standard created & still maintained by Renold for all roller chains.
The plates for these chains are 1.51mm thick which many classics, especially Nortons based their clearance gaps on.
Many people claim that these 10B1 chains aren't fit for motorcycle use which is plain false as the design is more or less unchanged since the 1920s.
Yes you can fit wider chains, if you have the clearance but if you don't, you will very likely encounter clashes with cases & sometimes frames.

In 1992, the standard ISO10190 was released that is essentially an addendum to ISO606 to specify a minimum of plate thickness which in the case of 5/8" pitch chains is 2mm.
An extra 0.5mm doesn't sound a lot but with both the inner & outer plates being thicker, this adds 2mm to overall chain width & I believe a bit more on one side due to the extended No.26 spring clip pin.
Incidentally, some of you will recall the GP chains Renold once made that became the essential chain for all the winning racers.
These 5/8" pitch chains (119058 & 119059 for 1/4" & 3/8" width) had the thicker plates as standard & therefore preceded the ISO10190 standard.
There were of course other factors in the GP chain design but the thicker plates were the most obvious.

So in a nutshell, if you're going to fit a 10B chain such as the IWIS M106L or original Renold, there should be no issue with any of your classics.
Both these chains are still referred to as "Industrial" chains though but that doesn't mean they're not fit for motorcycles.
ALL chains were industrial chains throughout the 1900s & were more than fit for use by the world motorcycle manufacturers.

One word of note regarding Renold specifically. There are 4 specific grades of chain with the one used on motorcycles being "Renold Brand", commonly known as blue box.
This is the chain that Velocette distribute to the classic dealers & sold in the blue & yellow boxes.
Some people have been known to pass off the cheaper A&S & SD chains for motorcycles but under no circumstances, use it.
There's also the higher Synergy spec that I use personally but as it was not produced until 2000, it doesn't have grandfather rights to classic motorcycle use.

If you're going to fit an ISO10190 chain, don't go riding it in anger until you made absolutely sure there's no interference.
Any such chains such as the Wassel Elite or the new Renold chains via their online shop are to this spec & therefore wider.
 
I see in the Renold catalog, the Synergy, 110056 10B-1 at 1.55 mm plate thickness, with max. pin length at 18.8 mm.
Their Syno Nickel plated with 2.0 and 1.5 plate thicknesses at 19.6 max. pin length,
a stainless at 2.0 and max. pin length at 20.4,
and a 300 series stainless with 1.5 plates and a max. thickness of 18.8.

any experience with what the max. pin length could be before interference - rubbing?

You are talking Norton tolerances over long distances modified by 50 years of use, so best to stick to the tried and tested thin chains like the AN one. If you want to go wider then measure your own bike to see what could fit. To measure some disassembly may be needed and bending of the chain guard.
 
Big old DID 530 early O ring chain fit right on my MK3, as per Comnoz advice. This is the DID 530 sealed chain for large bore road bikes that was available before the narrower VX type DID which is available now.
If memory serves it is about 1mm wider than the current VX 530 and doesn't have the fancy x rings. I can't seem to wear it out though!
Earlier bikes might have less clearance.
The 530vx dropped right on the 650SS, no rubbing. The 530vx has a pin length of 23.3 mm. There is also a heavy duty version , which is not needed with our machines. It is called the 530zvmx and the pin length is greater at 24.8 mm. Probably best to avoid that one, although it might fit a MK3 as my old O ring chain on there is similar. Anyway the ZVMX is more money and you don't need it. Most of us won't ride enough to ever wear out a 530VX. I am trying hard though!

That's all I know about sealed chains and Nortons.

All well & good, but better still, fit 5/8" x 1/4" sprockets & a DID x ring chain, & say goodbye to constant lube & adjusting. Each time I build a bike I do this, then spend time riding as opposed to faffing.
 
That's more or less what I was saying only don't bother changing sprockets if you have a MK3. Go xring 530, just drop the chain on. The 530 width sprockets will last a lot longer than 520 sprocket as the tooth pressure on a 520 is 50% higher than on a 530 sprocket. Plus most already have the 530 sprockets in place, just the chain to buy.
Earlier bikes, unfortunately it seems that the 530xring won't necessarily fit, although one member did fit one on an early 850 without problems.

Thanks for spotting my mistake on plate width when I wrote 1.51mm when it's actually 1.55mm. Gnats nadgers I know but size matters they say!
That will teach me to type responses without my glasses on & not proof reading as well as I should.

The Synergy chain you've referred to is dimensionally identical to the box stuff. It's the material & heat treatment that makes it special & cost more of course.

For the Syno & Stainless chains, I have to be honest I've not looked into them in any specific detail as they are designed specifically for sanitary applications such as food conveyors.
The bushes are also sintered to retain lubricant whereas Synergy & blue box have extruded bushes.
I don't know for sure why the pins are longer but I can find out if anyone's interested. I suspect extra allowances are made for the different application & materials used.
They are otherwise dimensionally the same as standard chains but again, I wouldn't try using them on a bike.
