  11. The reason a Triumph gearbox will jump out of gear could be due to one of any number of faults, or more usually to a combination of more than one Fitting a new camplate plunger and spring will certainly help but is rarely the real reason the gear won't stay in. If you eventually strip the box inspect every single item of the selector mechanism becuse it can all wear, and wear means that the movement of the gear lever isn't being translated into a corresponding amout of travel at the selector forks. The camplate on the 3HW 'box is made out of some sort of monkey metal and the inner tracks can open out quite dramatically, it can also strip away from it's shaft, which is steel, and the mating teeth with the quadrant can wear. If any of these conditions are present replace the camplate. Also check for excessive wear between the camplate shaft and the steel bush in the casing. The selector rod can wear which in turn makes the selectors twist on operation - the same one was used on all pre unit 'boxes so it's an easy fix. The selector fork ends can twist (due to wear in the preceeding components) or just plain wear out, as can the pins for the camplate rollers and the rollers themselves. They can be reclaimed, but it's not an easy job. Unfortunately the gearbox was redesigned for 1950 and the selectors are not interchangeable so new ones are a bit thin on the ground. At this point all you're left with are the gears themselves which are usually indestructable when used on the 350. A quick look will tell you if something is amiss. As an aside, another weak point on these 'boxes is wear on the floating bushes between the layshaft and the layshaft high gear. This can sorted by hard chroming the layshaft slightly oversize and reaming the bushes to suit - funnily enough, there's rarely any wear between the bushes and the layshaft high gear, which is a plus. Hope this helps, Stef
  12. I've been looking throught the RAOC Chilwell book, and of course Wally is absolutely right, if you can find out the relationship between the Morris Commercial sanction number and the relative WD contract number then things do start looking up. Luckily for me, in the Quad article in Wheels and Tracks N°29 Bart Vanderveen made the correlation of my sanction number 1794 and the WD contract number V3772. Unfortunately the information in the article becomes sketchier when he talked about the Mk III. I didn't know that any of the Morris Commercial records had survived, when I enquired at Gaydon about the CDSW they told me that all the Addersley Park records were burned when the factory closed down. This is very good news
  13. At shows I'll always wear the correct uniform for the vehicle - I just think that it completes the picture so to speak, although I suspect that my corporals stripes are starting to look a bit "young". Likewise, although I have absolutely no desire to dig trenches or suchlike, I have nothing but admiration for what I see the reenactors do at W&P - absolutely brilliant I think, although I must admit that wild horses wouldn't get me into an SS uniform..... In any case I think it all boils down to whether you feel comfortable with what you're wearing and there's no point in going around feeling like a pratt, because at that point the chances are high that that's what you actually look like..... We all share a common passion, so whatever flies our various kites is fine by me.
  14. I would have thought it pretty obvious that the earlier wartime vehicles were updated in many repects, especially when they were beneficial to the use of the vehicle - for example the permanent 4 wheel drive of the MkI and II quads was generally not considered A Good Thing, which is clearly why it was ditched for the MkIII. Motorcycle pannier frames are another that spring to mind - they were retrofitted to just about everything, or how many mid war pictures of CS8's and CDSW's do you see where the beautiful 8" CAV headlights have been ditched? All of them of course.. As for the engine, I've still to check the number on mine, but I'd be astounded if it was the original one.
  15. Richard, You're quite right there - it is indeed a happily modified quad - it started life out as a (relatively) early MkII, but received a pretty thorough makeover to MkIII spec - Canvas roof, doors with windows, transfer case with disengageable front axle drive, etc - although there are still alot of MkII peculiarities (no l.h. front side window, early master cylinder with remote reservoir, central throttle pedal, early type front axle location...). The rebuild plate and makers plate numbers do match up however
  16. Hello everyone. Can anybody shed some light on the REME plate I have on my Quad? Also, is there any way of knowing the original census n° of the Quad before it became 81RD76? Any help is much appreciated. Stef
  17. Don't - ever - sell - it!! Because from that day on whenever you hear a Meteor fire up you'll feel sick to the core..... Guaranteed.
  18. Steve, Like I said, if only for reasons of heat transfer i would go with a square section top ring. Whether scraper rings are necessary at all is a mute point, and seeing as my experience of cast iron pistons and their lubrication requirements is basically nil I'm really not the right person to give advice. I'd talk to someone that is used to working on engines of this age Stef
  19. They look like scraper rings, also called second rings or scraper/compression rings. The wide part goes to the top. The top compression ring has a square section and it's greater contact area also helps heat transfer from the piston crown to the block. There also used to be a top compression ring with a slight cutout to the top, they were called "step dodgers" or something like that, and they were fitted to engines as a "ring job" without bothering to give the bores a hone, because a square ring would risk smashing itself against the step. The cutout of one of these is obviously less than that of a scraper ring so you'll have to compare sections to see what you have. Hope this helps Stef (oops, Richard got there before me)
  20. Glad to see that you finally brought it home!!!
