I seem to have twisted the sliding part of my split link. Will i need to buy a new split link or can the sliding part be purchased separately? I should add i dont know the specification of the chain as it was on the bike when k bought it. Alan

I dont think you would be able to buy the split link clip separately, I think you might have to buy the complete split link

I don't agree, for the cost of a new link you are potentially risking the chain coming loose, with all sorts of possible outcomes, including serious injury.

I suggest you refer to this topic in FAQs to determine the chain size, then buy a complete link.

The link is not going to break .All it does is stop the side plate moving .if it is home in the slot then it is doing its job.if its dimensions have been changed by corrosion then a new one is needed.Ovalized holes in the side plates are a no no.

I’m not sure I would risk heating up the clip considering the cost of a new link is so low. The OP has said the clip was twisted, and sufficiently so to believe a new one was required. That twist will have imparted stress to the metal of the clip, and I agree the clip bears no longtitudinal stress which is all taken by the actual link. However,the clip does take a sideways force to prevent the link slipping out. The locating hole may be mis-shapened due to the twist and the metal weakened, heat will allow the main part of the clip to be straightened, and will also remove some of the stress damage that may have occurred but I would only use a clip like this in an absolute emergency. Remember a chain coming apart at even just 40 mph can do a lot of damage to both machine and rider. Is it worth the risk for a part that probably costs less than £5?

I understand what you mean, John - but if you heat the clip to red, you probably de-temper it, so losing the spring that holds it in place in the grooves of the pins. It may stay in position without a problem, but for the cost of a replacement, is it worth it?

And if there should be a problem which causes a serious accident and the clip is found to be the cause, what would the insurance company do?

Just not worth the risk in my opinion, especially as Alan admits he's not very skilled in these matters (no offence meant, Alan).

I havent had time to study the link provided in detail. Am I correct in saying I can tell the spec of the chain (and therefore the type of split link I need) by simply counting the number of links?

No, you need to measure the links, as per the table in the link supplied (no pun intended), or google chain sizes.

Above is a split link for sale on Ebay, if seller is correct should fit a D1. 

Might be worth a punt.

Surely simplest and safest would be to ring a chain supplier ( the one I use have a sprocket in their name ),I found them very helpful. Explain the situation and inform them you will send your link as a pattern, they will very likely tell you how much to send with your pattern, once they receive it , you will have a new link by return of post.

No, it is described as being for the primary chain. Best to measure your existing chain, compare with the chart and find the right chain number. As John implies (and numerous other posts), some sellers will supply a 420 chain (or link), which is OK if you have 420 sprockets. 420 is NOT the same as the original Renold chain though.

Looking at one of your previous posts (rear mudguard), I see that the sprocket fitted is a riveted one, so probably for a Renolds chain. Can't tell from the photo what the chain is, so you would still need to measure. One thing though - doesn't the Renolds chain use a different joining link, compared to newer sizes?

Thanks

Heres the plan: 

1. Look through parts receipts that came with bike 

2. Look for identification marks on chain

3. Measure chain and if thats not conclusive-

4. Send split link to chain dealer

 

The chain is new, not the original one by the way. Also rear wheel although fitted to a 1950 rigid frame seems to be from a later model, assumed to be a plunger. I am hoping chain and front and rear sprockets are matched.

If it's new it may well be a 'metric equivalent', which doesn't fit!

IF you have the correct rear chain fitted and Not a 415 or 420 chain
this is the correct split link and spring clip to buy

No receipt but found a T & G Motorcycles parts book in which '11b Renold Chain, split link (state model)' was underlined and next to it 5/32" (whatever that meant)

Anyway lots of the links were marked (see attachment) so presumably all I need to do is pass the info or copy image to a chain dealer and obtain the split link.

I took the dims in any case:

Pitch 12.3mm

Roller Dia 8.55mm

Width 5.5mm
