MG MGB Technical - Sump baffle drawing for 18V engine?
|Does anyone have a drawing of the sump baffle modification for an 18V engine (sump part no. 12H3541)?
I have read that it is available on page 457 of the Bentley MGB manual, could someone post a copy?
There are plenty of drawings around for the 18G/18GA/18GB engines in books such as
But these aren't correct for the 18V sump, also I noticed there is an error in the Special Tuning drawing (anyone else found it?)
Never had a problem with the drawing, except that if the sump's not deepened the baffle needs to sit a bit higher and that front turned up lip has to be flattened off a bit to suit.
Only error I can see is that 20g=.036" when we all know it's .0359"------ha ha ha ha
interesting 20g wire spec =.0348"
One would think 20g=20g whatever the material
Where is the difference with the 18v pan apart from marginally wider and slightly squarer accross the front of the well, the baffle still fits up---unless I'm missing something----?
|Willie, The difference I see with the 18V to 18GB sump is the right rear corner were the drain plug is - the 18V has a chamfered corner where the the 18GB is a rounded corner. The baffle drawing shows this as 1 1/8" radius so this has to be altered to make it fit (as well as marginally wider as you say). |
I realise these are easily adjusted but was just interested to see if there was a 'Works" drawing for the 18V baffle out there.
|Oh by the way, the error in the drawing in the Special Tuning Manual is at the front of the baffle. The radius on one side is listed as 1 1/2" and on the other side 1/2". It is obviously supposed to be 1 1/2" both sides - somehow the "1" got left off.|
This error is repeated in the Huffaker Competition Preparation manual but it has been corrected in the Mike Garton book Tuning BMC Sports Cars.
That is enough trivia for today - now for the AFL Grand Final West Coast v Collingwood!

Ripper Grandfinal, talk about down to the wire---that's how grandfinals should be
|That's the baffle made, now to weld in. I made a template for next time so I don't have to worry about all those 64th of an inch measurements when marking out!
