one of mine gets oil coming out of the breather hole in the dip stick.

I could agree with you, but then we would both be wrong

Hey Les, were we separated at birth, we`ll need to get DNA tests, hehe...first there`s the agricultural mechanics, now MOT testing!

Very good point, a random split link retaining clip from a particular batch, may not be a good fit for another random spare link, namely Alan`s. I missed that one!

Cheers

The problem seems to be no one (thus far) has split links for my renolds chain. Seems they no longer make it. The dealers I have spoken to/visited locally  tell me they can get a modern renolds split link that will fit but it wont be quite the same, I think they said it was 1.5mm wider. I thought a new retaining clip would be better than a new split link 1.5mm wider or re using the damaged split link I was trying to replace in the 1st place. Lesser of two evils if you like. 

The retaining clips look identical to the one I'm replacing but havent tried fitting them yet.

Hopefully it`ll prize on with a satisfying click and sit tight, job done. Blind end facing direction of travel obviously. Easier to fit while on the rear sprocket so the adjacent side plate next to one you pop on the joining link, isn`t inline with it and getting in the way. Pair of snub-nosed pliers, one jaw on the back pin of the joining link and the other jaw pulling the end of the clip in place...click it goes, make sure it`s sat in the grooves properly.

There are various designs of retaining clip, some more robust and of better design and inspiring confidence than others.

Noticed an Amal in-line fuel filter for sale recently and wondered if there is enough room to fit on a D1 rigid.  Hard to tell how big it is without seeing it in person, as it were.

Hi Alan,

Yes you`ll have room, they aren`t that bulky as you can see from the above pic, where inlet/outlet protrusions can be used as a diameter guide for the main body size. Bantam D1/3 owners on here seem to have got on ok with them. I think they look the part over modern filters, but I`m happy with cheapo plastic ones.

Do you have the old copper pipe fuel pipe c/w anti-vibration loop, if so you`ll need to replace with some flexi pipe.

Thanks. I have braided fuel tubing. Eventually I want to make the bike more authentic and replace the 360 carb with a 260 and reinstate the copper tube. 

Assume it's a case of winding some tube around something and soft soldering some fittings on. Are the fittings readily available?

That Amal filter and the copper tubing set-up don`t really match(however if I fancied such a set-up I`d find a way), but may fit your braided tubing ok, matching diameters being in order.

Fittings should be available still, and yes just coil copper tubing around a metal pipe or glass bottle of the correct diameter.

If your tank has been treated with an up-to-date sealant internally and has a quality fine mesh filter atop the petrol tap, that should do you if tank is clean of 70yrs of debris. A bit of grit can have the float needle off its seat and cause flooding on those carbs.

Hi Alan,

If you`re still having issues with being on maximum adjustment with a new chain, here a pic courtesy of Mags1 re a chain he photograped for his post, showing a half link...Post No4....** Please log in to view **

Coincidentally I had looked at this thread previously, but before the chain was featured. Anyway thanks very much, never seen a half link before, or a chain with a split pin arrangement.

I could well be wrong, but I thought a half link was part of some Bantam rear chains?

Once chain wore in well, simply removing the half link would bring you back to original fit maybe?

Just thinking about this, how does the half link mesh with the sprockets? Surely they are designed to work with chains with uniform size links.

Yes, the Amal filer would only be used until I get the copper sorted (which may never happen). I dont think my tank has been sealed but so far no issues, I assume there is a gauze in the petrol tap. Anyway, moving back to the Amal in-line filter, whats actually inside it- just a mesh that can be cleaned out in petrol or is there a consumable paper element or something?

The half link adds just one pin, not three as in fitting two outers and two inners as per usual. I think.

No change, rolers are all still same width.

Some competition pushbike chains are 100% half links....every link thereof.

The top example `two-stroke` shows is the strongest solution(as half link is integral part of a complete chain), because the half link is already secured with peened-over pin. Just add traditional split link....or with the right kit you can do away with a split link and have a continuous chain, by using soft-headed pins and peening over.

With the bottom example it can be fitted with a full split link in addition(certainly not advised to have two split links,especially together!), or will need a roller removing from your chain to expose the two opposing side plates, to slot the half link wasted section  in, then pin fitting & peening over. If you`ve got the correct kit then it will be just as strong as the above one that comes already fitted to the chain....plus again, you can fit pins with soft heads and peen over for a continuous chain....therefore,no split links, no weakest link!
