Neville, there never were any torque settings quoted for British motorcycles at this time and in the case of a crankpin, very subjective anyway! Your figures sound reasonable and I'd try to tighten until the nut flats align with the lockscrew. I have seen both nuts and screws filed to meet up, probably as a result of meeting the end of the thread!

Try this link:  https://cybermotorcycle.com/gallery/noxal/   And a word of advice, always take the assertions of a previous owner with a pinch of salt!

Sorry if you've already done the research and eliminated it but the 'before' pics look like a Noxal S11 from 1929 as shown on the Noxal brochure of that year. There is a pic of the chassis as well in the brochure

Neville, congratulations on the number retention, not easy to achieve these days as DVLA are quite tough. And that's a great number, it will probably considerably increase the number of "I had one of those" bystanders when you finally get to go to an event! I've built a few Bullets over the years and I'm currently working on a late Bighead 500 special so feel free to contact me at trials59@yahoo(DOT)co(DOT)uk if you need any assistance. My last one (a 1955 350) was finished and sold last year.

Early 350 Bullets had a loose centre bearing on the outside of the d/s crank but nowadays we use 2 identical one piece bearings. So from the outside, cork seal, shim, bearing, spacer, bearing. Of course you will have heated the case as much as you can, you need to do this because the assembly sequence is a little fiddly and can be slowed if there are any delays so you need to retain as much heat in the case as possible. You might even need to pop it back in the oven briefly. I freeze the cork washer as well as the bearings, helps preserve it from the heat. Enfield changed the details of this assembly a couple of times before standardising the design for the big crankcase re-design in 1956 so some workshop diagrams show a slightly different arrangement. I won't list them all here! Any more questions, please ask. REgards, Mark
Sorry I left a shim out, the cork seal is sandwiched either side by the shims.

Sorry, bit of a tangential question here but I think the OP has had his answer! I notice in the second frame picture that the bottom bracket casting (it is reminiscent of a bicycle component perhaps unsurprisingly,) has a distinctive raised triangle casting identification mark? Is this the mark for the Sun component company? It also appears on a lot of Royal Enfield cast iron components including the head stock castings and I've often wondered who made it.
Thanks for the mental stimulation,

REOC Home Counties Autojumble 18/4/20 Postponed!

Well the headline says it all I'm afraid. The village hall is officially closed for the time being and we wouldn't be going ahead anyway. We will re-schedule for the autumn hopefully and I will give plenty of warning! Any of you who paid for stalls upfront and want your money back now please contact me on the email I gave originally, otherwise I will hold your booking over to the new dates and refund then if the new dates don't work for you. Thank you all for your support so far, it was shaping up to be a very busy event! REgards, Mark

« on: March 11, 2020, 09:33:54 AM »
Thanks R, I've looked at the picture of the carb flange again and there is the faintest mark after the / which could be a 1 making it /10. I also looked at the various mower and cultivator websites (who knew?) and the Shay range looks very likely, the Shay Rotogardener being a good example of how the worm drive would have powered the cutting head. It also explains the horizontal fitting, the non drive-side crank journal being cottered to fit a pull cord starter. I'm now thinking this is a JAP engine, not an RE product but I'll do some more on that. The beauty of sites like this one is that someone may have an idea of where to look, the internet might make searches easier but as any librarian will tell you, without an index, it's rubbish!
Thanks again,
REgards, Mark

I'm having trouble getting the pictures of the carb from Whatsapp (yeah, I know,) but I can tell you that it has AMAL clearly marked on the side. I really don't know how I missed it first time! Flange is stamped 343/0 but is a bit faint.

Depends what you mean by expensive but you need to research the whole subject to be able to judge! So, look at the website for Electrex World for an idea of what can be done.

Thanks, R, I'm waiting on detail pictures of the carb. In the meantime an expert has identified the top end as 1948 type Model RE.

Rex, the mention of the 'hydraulic engine' was just an example of the type of thing Enfield were doing at the time, I'm not saying this is one or getting involved in a discussion about tank design! The 2-stroke engines used in other applications apart from the bikes are a bit of a mystery. Lawn mowers we know but there is mention in some of the books of other uses, even chainsaws. But please don't shoot off on that tangent!

This site seems to be a bit sleepy of late so this recent discovery by a pal of mine may interest you all. From the garage clearance of a well known and long time Royal Enfield expert comes this odd beast. It has been suggested by someone who knows RE 2-strokes well that the top end is Flea (RE 125,) but there are no numbers on the cases at all. The big puzzle is the curious worm drive. Also, if the carburettor bowl (no markings on carb,) is oriented downwards the engine sits on it's side with the other crank shaft pointing upwards yet this shaft has a cotter pin cut away, presumably for some sort of starter, but that puts it in a horizontal plane? The other shaft has a taper, clutch? Or drive of some sort? But if a clutch, why outboard of the worm? We know Enfield made motors for their lawn motors and during the war made something described as 'oil engines' (which are presumably hydraulic units) for driving tank turrets - could this be for that purpose?

Rex, I thought that too, which made me think it might be something low revving and maybe automobile. Diesel perhaps? Anyway, a nice puzzle for a cold day!
