Mon Dec 14 10:10:52 MST 2020

The blanking plate is available new as a Triumph TR 6 part.   Moss # 832 550

Or we have them available as well. They replacments are a thicker piece of material so they do not warp and leak.

Yes thanks for pointing that out however, before we confuse everyone, I should add that what you have mentioned about the spacers does NOT apply to the 6 cylinder engines that used that blanking plate. Sixes just used 5/16" UNF nuts with spring washers.

  May I just add to this because on face value this plate fitting arrangement appears to be a bit strange? On the block are two studs over which the plate is fitted but the long studs have collars to space out the nuts and spring washer on the studs that would be too long. The question is why not use shorter studs? The answer I believe is that when engines were being made it was not known if the engine was to be fitted to an Austin Atlantic or an AH100. Production is an assembly process and taking out long studs and fitting shorter alternatives would slow down production. It was much more straight forward to fit either the mechanical pump or a blanking plate with collars to take up the length when a thinner plate was fitted on a 100.

  The part numbers are

  1 Plate                 1B2386
  1 Joint washer     1E504
  2 Stud                  2K3451
  2 Collar                2K9631
  2 Nuts                  2K39
  2 Spring Washer  2K1211

  Best regards

    Something similar on the four cylinder block.  I am sure there is  factory cover for this opening in the block, but I did not have one with the block that was given to me as a basis for my engine build.  David at British Car Specialists makes up plates just for this purpose.  Unless you are doing a concours restoration, David's plate will work just fine.  In fact I just installed mine.  Here it is before painting.

    Hello

    Attached is a photo of the first six-cylinder C26W engine fitted to an Austin-Healey (BN3/1) that shows the plate towards the front.

    The engine has since been rebuilt and is back in the car.

    Yes Harold, The earlier 6 cylinder engines used this blanking plate to cover the fuel pump hole.

      Full disclosure the attached picture is not my engine but mine should look similar some day. On the side of the block there is a mounting point for a fuel pump just to the left of the SP casting mark. It looks like versions of this engine block used in other cars had a cam driven fuel pump. I am interested to know the size of the hole in the block for the cam driven pump and if BMC ever supplied a blanking plate to cover the hole. Part number appreciated if it exists.

      Thanks in advance.... Harold
