dog107 Posted November 4, 2006 Share Posted November 4, 2006 Hi I'm doing some work for the Air Museum at Elvington. They have a Chevy C15A which has a 6 cylinder bedford petrol engine in it. Does anyone know how to identify which Bedford engine it is. All I know is that it has Bedford embossed on the top cover. I'm trying to get it running and want to set all the gaps etc. cheers Quote Link to comment Share on other sites More sharing options...
Guest matt Posted November 4, 2006 Share Posted November 4, 2006 Hi, Would this truck be a C15A water bowser? Matt. Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted November 4, 2006 Share Posted November 4, 2006 They have a Chevy C15A which has a 6 cylinder bedford petrol engine in it. Does anyone know how to identify which Bedford engine it is. All I know is that it has Bedford embossed on the top cover. Usually the Bedford 28 hp engine (as in Bedford MW, OY, etc.) is substituted as it is of the same capacity as the Chev, but that engine does not have "Bedford" stamped in to the rocker cover. Is the cover secured to the head by screws around the rim? If so, it is a post war version known as the 214 cu.in. (again similar capacity).

dog107 Posted November 5, 2006 Author Share Posted November 5, 2006 Hi thanks for your replies. Matt, The C15A has a GS body on it. Richard, The cover is indeed secured with i think 4 screws around the rim. Do you know when these engines were in production? Has anyone done this type of conversion before, as in personally involved. I have been told that the army converted Chevy's to Bedford's but I am presuming that they use a QL type engine. Can anyone tell me if the clutch is from the Bedford or the Chevy. cheers michael Quote Link to comment Share on other sites More sharing options...

Michael, Then you have a 214 engine, not exactly sure when it was introduced but around mid-50's, they did evolve over the years, last used in TK and TJ up in to early 80's. The QL had a 28hp engine bud with deep end in sump with strainer on oil pump, it would not be necessary to use that engine in a CMP because the front axle is further forward than a QL, giving adequate clearance. You hear stories that the army converted CMP to Bedford engines, but I am certain this was not a general case, because the British disposed of their CMP vehicles early on, having more than enough British made vehicles and spares to be going on with. These mods would have been done in civvy street, undoubtably. I have not fitted a 214 to a CMP, but have done it to a Bedford MW. The 214 used, was a army rebuild, for a TK, the clutch housing had to be changed over in order to get the rear engine mountings to fit, then it was found the flywheel was smaller, and starter different. Other than that the rest of the engine was the same. To answer your question on the clutch, you will have to remove it or take the pan off and post a pic of the clutch. The drive plate can be relined by a motor factor or matched up for a replacement. Richard Quote Link to comment Share on other sites More sharing options...
dog107 Posted November 5, 2006 Author Share Posted November 5, 2006 Hi Richard Thanks again for your reply. I will get a photo of the fly wheel. I only go over to the museum once a week and I can't go this week so it will be a couple of weeks before I can post the picture. The 214 is mounted a little bit higher than the Chevy but the fly wheel sits through the second cross member which has been cut back to allow for this. It looks like there should be a cover over the fly wheel but this is missing, I think there is not enough room for the cover to be fitted. Thanks again michael Quote Link to comment Share on other sites More sharing options...
dog107 Posted November 16, 2006 Author Share Posted November 16, 2006 OK this is just a test to see if I did this pic thing right. http://snap32.photobox.co.uk/17522927ae45224af918c7f7a656b987995da456dc698a3aafb96f33.jpg[/img] Quote Link to comment Share on other sites More sharing options...
dog107 Posted November 16, 2006 Author Share Posted November 16, 2006 ok see if i can get the picture bigger. http://i135.photobucket.com/albums/q135/dog107/Chevy/IMG_2026.jpg[/img] Quote Link to comment Share on other sites More sharing options...
dog107 Posted November 16, 2006 Author Share Posted November 16, 2006 Right I'm not sure that you can see anymore in the bigest version. It is supposed to show the timing mark in the timing window. I have decided that the fly wheel is chevy as TDC is stamped UC (upper center). this is how it shows it in the chevy manual. Can anyone tell me if the bedford has the same before TDC as the chevy. i.e. can I use this mark. I'm also looking for plug and point gaps. and anything else that you may think usefull. cheers michael Quote Link to comment Share on other sites More sharing options...

Richard Farrant Posted November 16, 2006 Share Posted November 16, 2006 Hi Michael, A Bedford flywheel ignition timing mark is actually a steel ball set in, so that when a neon timing light is used it shows up bright. Plug gaps are 0.037" to 0.040" inch Points are 0.010" - 0.012" inch Timing degrees are not actually stated Richard Quote Link to comment Share on other sites More sharing options...
dog107 Posted November 16, 2006 Author Share Posted November 16, 2006 hi Richard Thanks for the info. The timing mark is indeed a steel ball set in the fly wheel. So i guess that makes it a Bedford fly wheel. From that do you think I can assume that it is correct for the engine? cheers michael Quote Link to comment Share on other sites More sharing options...

Could you take a photo of the back of the flywheel showing rim and clutch, that should give me more info. Richard Quote Link to comment Share on other sites More sharing options...
dog107 Posted November 17, 2006 Author Share Posted November 17, 2006 Hi Richard I'm having problems with the photos. I load them they are there for a bit and then they disappear. With all the excitement with the photos I neglected to say that yesterday it fired on more that one occasion but wouldn't run. The plugs are very wet when you take them out but it will only fire if the choke is fully out. Next time I'm over I will set all the gaps as per your info and that should help as well. If I get time today I will try with the photos again. thanks again michael Quote Link to comment Share on other sites More sharing options...
dog107 Posted November 17, 2006 Author Share Posted November 17, 2006 Ok another go with the pictures[img width=640 http://i135.photobucket.com/albums/q135/dog107/Chevy/IMG_2021.jpg[/img] this is the flywheel and timming mark cheers michael Quote Link to comment Share on other sites More sharing options...

Richard Farrant Posted November 21, 2006 Share Posted November 21, 2006 Ok another go with the pictures this is the flywheel and timming mark Michael, I see you have posted another pic of the flywheel. I can see enough now to think that it is a Bedford flywheel, so timing marks will be appropriate for the engine. Richard Quote Link to comment Share on other sites More sharing options...
dog107 Posted November 21, 2006 Author Share Posted November 21, 2006 cheers Richard I'm glad you happend by, as I load the pictures and they hang on in there for about an hour and then they vanish! Next time I'm at the chevy I shall set it up as per your info and let you know the results thanks for your help and patience michael Quote Link to comment Share on other sites More sharing options...
dog107 Posted April 29, 2007 Author Share Posted April 29, 2007 Hi again I finally got back to the museum and the Chevy. I set it up with the new settings (thanks to Richard) and gave the starter a spin, nothing. I messed around a bit and took a plug out to check it, it was as dry as a bone. So of with the air filter and in the time honoured fashion I poured half a cup of petrol down the carb. Pushed the starter and it fired straight away. It ran for a bit and then stopped. I kept doing the petrol down the carb thing hoping that eventually it would start to draw fuel itself, but to no avail. So now that I have the timing sorted it has developed a fuel problem. At least I know what to do next. Thanks for all the help cheers michael Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted April 29, 2007 Share Posted April 29, 2007 Michael, Slacken the fuel pipe on the carb, to see if fuel is up to there, if it is, then it may well be a stuck needle valve in the float chamber. Quote Link to comment Share on other sites More sharing options...

Is you engine a 28hp or a later 214? Quote Link to comment Share on other sites More sharing options...
