  1. There are a small number of manifolds listed as suitable for the 28HP on Ebay in varying states and at varying prices! My son has a truck with a similar engine which had the same problem. We skimmed the exhaust manifold on a milling machine but also had to do the same to the head as the joints had clearly been blowing for years and this had eroded the mating surfaces, so look carefully at the head as well as the manifold. If you go down the route of machining the exhaust manifold, you might have to remove the same amount of material from the inlet so that both sit together as they should. Best of luck Alan
  2. My Matador is fitted with the Westinghouse full air braking system. There is not really any back pressure against the foot on the pedal and it goes down to the bottom but the lower you push down the pedal the harder the brakes are applied. When driving you have to judge how far down to press the pedal to slow the vehicle as you intend rather than rely on sensing how hard your foot is pressing on the brake.
  3. I don't know where it is located but it appeared on here looking ready for a bit of tlc in a thread a few years ago.http://hmvf.co.uk/forumvb/showthread.php?7379-Diamond-T-Gallery&p=306808#post306808
  4. Earnshaws moved from Midgley down the road to the former Denby Grange Colliery site some years ago. The original yard is now occupied by houses and as far as I am aware the few matador bits left, basically a pile of wheels, were disposed of. You could give them a call, but I am not optimistic.
  5. The mk2 armoured car appears to have been powered with a 9.65 indirect injection engine, not the 7.7 direct injection unit as fitted to the matador. If you look at the AEC Society website and trawl through the "Contribution to victory" publication there is quite a lot of information there that you might find useful.
  6. I have a parts book which lists tools, etc supplied with the first 1100 or so vehicles. Many of these are special workshop tools, others are what one would expect to find in a kit carried on the vehicle. It is not clear to me what would actually be carried in service. If no one has the information to hand I would be able to scan the pages if it would be of use.
  7. Mallard Metal Packs http://www.mallardmetals.co.uk or several others who supply the model engineering fraternity should be able to fix you up.
  8. I am currently going through the brakes on my son's CMP so the time is not entirely wasted. The job is becoming a something of a war of attrition, buying parts as near as possible to the originals, then making them fit- including brake union nuts!
  9. Curiosity aroused, I have dug out a copy of Machinery’s Handbook of 1944 to learn more about SAE (Society of Automotive Engineers) threads. There were four categories, Course and Fine series, 8, 12 and 16 pitch series, Extra Fine and Special Pitches. Pipe threads, aeronautical screw threads and several other American systems are not covered by the SAE specifications, at least at the time of publication. The Course and Fine series and 8/12/16 series are similar to American standard threads. The Extra Fine and Special Series are particular to SAE. All types had the same American standard profile. To explain:- The Course and Fine series are said to be just the same as American Standards threads, which with some modifications later became UNC/UNF. The 8/12/16 series had the same pitch (threads per inch) for different diameters. For instance, the 16 tpi series ranged from ¾ “to 4”dia. and was said to be suitable for adjusting nuts and bearing retaining collars. The Extra Fine series ranged from 1/4” to 6”diameter. As an example a ½”dia. thread has 28tpi. The Special Pitch series is more complex as each diameter has a range of pitches. A ½”dia.thread can be 14,16,18,24,32, or “for special applications”28 tpi. Each category also has a range of up to four manufacturing tolerances, specifying limits to achieve looseness through to tightness for different applications. Until today I thought that our Whitworth based thread system was complicated!! :nut:
  10. I think that you would be best advised to measure the diameters of the nuts and use a thread gauge to establish the tpi. I am currently doing the brakes on a Chev CMP which is piped with 1/4" tube. The male threads on the flexible hoses are 7/16 x 20 tpi, which is UNF, but the female ones are 7/16 x 24 tpi, which my Presto booklet describes as NS-"special threads of American national form". A bit confusing but apparently American practice on many vehicles of that era.
  11. I have used safetek - The Cleckheaton branch is not too far away from where I live- several times. They even relined a tiny pair of shoes for a push bike for me on one occasion! http://www.saftek.co.uk/index.html
  12. Basic information and photographs of command vehicles (p.30/31) and armoured cars (p.50-52) is to be found in the AEC publication "Contribution to Victory" - available here http://middx.net/aec/victory/001.htm It is well worth looking at and covers Matadors and also other lesser known wartime AEC products such as flame throwers and tank engines.
  13. Going back to the lining material issue, I would be surprised if Saftek were unable to help. I have always found them obliging and able to deal with one offs. http://www.saftek.co.uk/
  14. Be careful with that shovel MW. I've come across the odd mortar shell when walking around Langsett!! Dave- Welcome to the forum
