flyingfleasteve 10 Posted February 9 Hi All. I have been following this site closely and I have been reading about the various Triumph projects and restorations taking place. It's somewhat inspired me, with this in mind I thought I would share the rebuild of my own 1940 Triumph 3SW. I have owned the bike for approximately 2 years and when purchased it was a non runner. With the 75th D-Day anniversary approaching I thought it would be fitting to restore it to its former glory and take it to France this year. Although the bike,when purchased, had a large number of 'non original' parts fitted I was drawn to it because both the engine and frame numbers appear to be the same original pairing when it left the factory. To add, this particular machine was part of contract number C6128 which is also nicely stamped on the engine casing and as I understand one of the last to come out of the Coventry factory before it was bombed in November 1940.

flyingfleasteve 10 Posted February 9 I have over the last year, in amongst other projects, prioritised getting the bike running, the eagle eyed amongst you will note the carburettor it came with was incorrect, hence there was a bit of a delay, until an original one could be sourced. During this period I took the opportunity to remove some of the later 'additions' and replace with more period ones. I.e the rear mudguard stays, exhaust, silencer, DU42 headlamp, 4 pos. switch, CZ27 ammeter and so on. Share this post Link to post Share on other sites
flyingfleasteve 10 Posted February 9 Now running, I decided to give the bike a full strip down in preparation for paint. This, as always, highlighted a selection of issues. Firstly the petrol tank has some major leaks and poor repair jobs. Secondly the two main shaft bushes, within the gear box, have completely failed. Upon inspection there are also signs of corrosion, therefore a full rebuild is now underway Share this post Link to post Share on other sites
flyingfleasteve 10 Posted February 9 This week the gearbox is almost back together, clean and lubricated thoroughly and most importantly new mainshaft bushes made and pressed in Share this post Link to post Share on other sites
flyingfleasteve 10 Posted February 9 So how does the bike look as of today......... Still lots to do! 1 Share this post Link to post Share on other sites
flyingfleasteve 10 Posted February 9 Finally got the correct 1" bars! Share this post Link to post Share on other sites
HotBed 10 Posted February 9 Did you get it from Brian Tillin ?, I’ve just bought one off him with his front brake rod kit, good luck sourcing the correct handle bar levers. Share this post Link to post Share on other sites
HotBed 10 Posted February 9 Where did you source your headlight ? Graham. Share this post Link to post Share on other sites
flyingfleasteve 10 Posted February 9 Hi Graham, yes the bars came from Brian, I am very pleased with them. I was fortunate enough to have a headlamp tucked away as well as 1” bar levers, you are right these solid style 1” levers arnt the easiest to find....

HotBed 10 Posted February 9 Did you buy your exhaust already dulled down ? Share this post Link to post Share on other sites
flyingfleasteve 10 Posted Sunday at 08:52 AM The exhaust was purchased unfinished, I then sprayed it in a good quality dull silver heat proof paint.... Share this post Link to post Share on other sites
Ron 16 Posted Sunday at 09:17 AM Just a heads up chaps. The exhaust pipe clamp at the cylinder on Triumphs is a finned clamp. I realized ages ago that I'd missed it on my own 3SW. It's quite a generic type and I bought one from Armour's in readiness to blast and paint black sometime. Ron Share this post Link to post Share on other sites
HotBed 10 Posted Sunday at 09:41 AM I did wonder, as I’d seen the finned one on your 3HW, I just thought it was a later mod. Share this post Link to post Share on other sites

HotBed 10 Posted Sunday at 09:49 AM (edited) Ron, when you painted your 3HW exhaust, how many coats did you apply ........ 6 ?. Graham Edited Sunday at 09:50 AM by HotBed Share this post Link to post Share on other sites
Ron 16 Posted Sunday at 09:50 AM (edited) 21 minutes ago, HotBed said: I did wonder, as I’d seen the finned one on your 3HW, I just thought it was a later mod. It's the same finned clamp on all three WD models and some of the pre-war models.# E1270. Ron Edited Sunday at 10:02 AM by Ron Share this post Link to post Share on other sites
Ron 16 Posted Sunday at 09:58 AM (edited) 9 minutes ago, HotBed said: Ron, when you painted your 3HW exhaust, how many coats did you apply ........ 6 ?. Graham 3 or 4 I guess. I'm probably guilty of not following the instructions to the letter by over coating too heavily........I just can't help myself....But it seems to work ok. There's less heat involved with an OHV. I've only done about 40 miles on my 5SW so far, so we'll see how it fairs with some decent mileage. It's bound to tarnish around the first bend and if it gets too bad it's only a total of about half and hour to remove and replace the system .....plus rubbing down and drying time in between.

flyingfleasteve 10 Posted Sunday at 10:54 AM Cheers for the heads up Ron, funnily enough I do have a finned exhaust clamp, it was fitted originally, but at the time I was unsure whether it was original or not, I best dig it out! Graham I will check the paint brand and let you know! Share this post Link to post Share on other sites
flyingfleasteve 10 Posted Sunday at 11:06 AM So some of the missing parts I have managed to source and purchase are now being delivered thick and fast. This weeks delivery includes a gasket set and more excitingly (I know, sad) an early clamp type MCR1 regulator as found on both the Triumph 3SW / 3HW etc.. and the Norton 16H. The lovely thing about this Regulator is it retains inside the cap, orginal military paint, but also stamped above 'FADE' is 'Lead Acid',which I am led to believe is an early 39/40 item. A lot of work to do on it but I think it will be a nice little addition when restored! Share this post Link to post Share on other sites
HotBed 10 Posted Sunday at 11:24 AM (edited) Can these regulators be restored ?. Edited Monday at 10:26 PM by HotBed Share this post Link to post Share on other sites
Ron 16 Posted Sunday at 11:30 AM Yes you are right about the regulator Steve. 'Lead Acid' was stamped on the early war regulators to distinguish them from the previous Ni-Fe (Nickel Iron) type. As time passed and everything was fitted with lead acid batteries, the stamping was dropped. The nice thing these days is, if it doesn't work, you can gut it and fit a modern solid state regulator inside and solder the wires to your original posts, so it looks all original from the outside. I recommend these.........From heart ache experience 😕http://dynamoregulators.com/dvr2.php Ron Share this post Link to post Share on other sites
flyingfleasteve 10 Posted Sunday at 11:36 AM I will give it a good clean up and then test it, fingers crossed it will be ok but if not I think a solid state regulator is definitely the best way forward! Share this post Link to post Share on other sites
flyingfleasteve 10 Posted Sunday at 11:41 AM On a separate note can I ask how you WD bike owners apply/applied your number plate letter/numbers? I know there’s a few companies out there making good stencils but I have seen a few original/period number plates with the letters and numbers hand painted. Is this how all period plates were created? Share this post Link to post Share on other sites
Ron 16 Posted Sunday at 11:51 AM Well considering that our WD bikes wouldn't have had registration numbers, it's just a case of whatever pleases you. I just buy number plate digit stencils from https://www.axholmesigns.co.uk/ Or you can buy waterslide numbers from Marcia at https://classictransfers.co.uk/product-category/registration-letters-numerals/ Ron Share this post Link to post Share on other sites
flyingfleasteve 10 Posted Monday at 05:48 PM One of the hardest parts to source to date was an orginal field stand. My particular bike has the later welded lug, 6 months of searching I found a genuine field stand tucked away in France, a little worse for wear but solid all the same. It finally arrived through the post today, still with signs of military paint in places too! Share this post Link to post Share on other sites
