    The bolts holding the diaphragm on are 2BA which is 4mm.

    Relying on the spanner size to identify a bolt size can be misleading, 10years ago Tim Leech was trying to ascertain the correct fixing for the two parts of the pump body

    As I had a spare pump and the means to check the bolt, it turned out  to be a 1BA bolt with a 2BA size Head

    It is not uncommon to find non standard combinations of shank and head size

    OD is 0.207" pitch measured with thread gauges is 28 tpi

    1BA is 0.2087" OD and 28.2 tpi

    As the pumps were British made I would have expected it to be to a British Standard of its Time

    Having said that the head size is 0.321" AF which corresponds to 2BA.

    So using 2BA bolts wouldn't look out of place, neither would M5 as the head is pretty much the same size, (0.315")

     

    There are other anomalies with the pump top itself the inlet fuel union bolt is M18, if the holes are drilled for the fuel stock locking plates they are M8 the nuts on the stud are  5/16 Whit and if I remember correctly the rack bushes are M20, The Injector pipe nuts at the pump end are M14 despite the fact that they have a 3/8" Whit Spanner Hexagon

  2. It depends upon what type of thermostat housing that is fitted, if it is a a single type then unless it has been modified then it has a different type of thermostat with the bypass cut off as a sliding vane attached to the outside (No 27). They are larger in diameter than the twin housing which uses a smaller one (no 30) more commonly found in older vehicles (2" dia from memory.) The later type  https://gardnerspares.com/product/74-degree-thermostat-drop-in-unit/

  3. It does help when you have lived in the area for a good few years, another image taken by the late Alan T Smith M.B.E at the 1962 Rally, the yellow pontoon conversion was our family boat. so I had a bit of ahead start.

    With regards to Coombe Hill Canal the early ordnance survey of the 1830's does not indicate a lock at the Severn, but then the scale to which the map was made might not show it anyway. The first ordnance survey was as published after the canal was abandoned, but still shows a lock, The 25 inch scale indicates a mitred pair of bottom gates and a single top gate. Which raises the question as to the type of craft that used the Coombe Hill Canal.

    As to the Scottish image the posting was to discover if anybody knew of this waterway. It is the Arisaig Canal and the 6 in ordnance for Inverness shire shows the route.

    And now a more simpler image which links a waterway with the iron industry as well as engineering

    This is 'Seaford' rising up Bumblehole Lock on the Staffs & Worcs. The year 1975 I think. Everything looking very smart so, perhaps, off to a Rally. Someone may recognise the captain. Or it could be you.

    Most likely Bob Derricott as he owned Seaford at that time, a picture would allow confirmation.

  6. As I remember the estates department was in the same building maybe before it became the shop, I remember visiting there probably with my father for something  in the 60's or early 70's

    Yes it was  Alfred Matty's Yard at Coseley

    The George is seen on the bank

    But, the basin had some interesting craft moored there and the crane states Matty

    And now another where was this Canal Shop ?

     

     

     

    The George is one half of the Dudley Canal Trusts replica of the double ended Gorsty Hill Tunnel tug that was built for use on the tunnel trips, it wasn't successful so was converted to two separate boats I think by Dave Harris the other half being William, both still in current use.

  7. Make sure that the rack is returning properly, if you leave the stop lever in the stop position after stopping the engine there is a good chance the rack will stick, especially if it has a low tension return spring fitted to lower the tick over. It is pretty much impossible for the fuel gallery in the fuel pump to empty to a point where the engine will not start,  unless there has been a catastrophic failure within the pump body. They will run on the fuel in the pipe from the filter for about 60 seconds. Are you using the cold start?

    The bridge number is of importance, but does it have to be a specific location but a representation of a narrowboat passing under a bridge.

     

    Is this plaque ceramic or metal and and is there anything on the reverse? 

    The bridge number appears to be 01 or Q1, I only have a photograph to work with. It is a brass plaque It is one in a friends late husbands collection which her sons are mounting on a board for her as a memory. I have asked if there is anything on the back. I will add any further information which comes to light. I find it odd that there is no date or organisation on it.

    To me, item 55 in Split Pin's previous post looks like the oiler screw.  Item 55 is the felt pad and stuff that holds the oil.  

    Last time I had a pinion off there was no need to remove them, but it does seem like a good idea.

    I would agree that it looks like a spring and oil pad but there is an oil cup shown behind it. Non of the ones that I have dismantled have had a spring just a short screw to allow oil to added, so it can possibly be ignored. I have dug out the book from which the picture was taken and there is no mention of the need to remove the items. Text from the book.

    I think these starters have two leads to the starter ,so they can be used on insulated return systems that many old trucks had ............anyway ,two leads solves a lot of the problems people have with poor earthing affecting starter performance.

    They are manufactured with both insulated return and case return, and they both have the two terminals.

    Thanks for that - the picture certainly helps, and it doesn't have any problematic springs to go flying across the workshop! Just to clarify on the first picture, is there any relevance to parts 54 and 55 being shown? E.g. do they need to be removed prior to starting to remove the split pin and nut?

     

    Thanks

    i have dismantled a number of these units an have never encountered those items, but if they are there then I would suggest that they need to be removed before removing the pinion. The illustration is from a book published in the early 1950's so may be applicable to units manufactured in the 1940's. Another couple of pictures that may help

    I dont believe anyone missed your interesting and useful post, it seems that there have been various boatbuilders and related works in Diglis over a relatively short time, despite Diglis basin being only able to accommodate a fairly small area for boat builders/ works. It would be useful for the OP to know when Watercraft started and finished and whether they took over their area from others such as Bryan Jones, it may interest the OP and others coming back to this at a later date perhaps. Its also stimulated some pictures which has been really interesting to see from the 60s. 

     

    Pinders and Grist Mill  current structures seem to figure later. I was always under the impression that the dry dock was owned by BWB in the 80s but that may well be incorrect.   

     

     

     

     

     

     

    The dry dock was owned and run by BW up until about 1990. I used it in 1987 and again I think in 1988, I feel sure that the next time I went to book it it was under the management of Pinders. The day to day management under BW at that time was carried out by Roger Hatchard. Stourport was also a BW dry dock which was subsequently leased out to a third party.

    that’s an interesting photo, 

     

    so while Browns Bridge is clearly a recent construction, is the lift bridge in its original position?

    or was it brought from elsewhere?

     


     

     

    And before there was a bridge or very much of the museum

  14. The wheel drives a gear pump which is piped to a double acting cylinder, so depending on the direction of rotation of the hand wheel will engage Ahead or Astern.

    The bowden cable connect to the gearchange mechanism and moves the position indicator.

  15. Ferrybridge was my original inclination but my memory suggests that the river-canal bank is much higher now, and I don't remember the Aire being as wide as it appears in the photograph.

    Maybe the bank was raised when the locks were mechanised.
