1952 MG TD Restoration Part 3

Disassembly and inspection of the engine.

[@glennbrymer4065]

My late brother had a MGTD. This was back in 1954, in San Angelo Texas. It was great fun racing around on the country roads.

14:43 The first computer 'bug' was a moth that managed to get itself caught in the contacts of a relay in Harvard's Mark II computer, back in 1947. These very early computers used relays as the automatic switches and memory elements. This was long before transistorized computers, and even before vacuum tubes. Admiral Grace Hopper was there, and she loved to tell that story every chance she got.

Nice catch, that was exactly what I was referring to there. You might be the only one that got it!

The White Link's on the timing chain are for camshaft timing. They are used when the number of teeth on the driven gear/sprocket cannot be cleanly divided by the number of teeth on the driving gear/sprocket. When used on gear's it's known as a Hunting Tooth. Way back then, it wasn't so unusual for the camshaft to revolve half a dozen times before the mark's came back into alignment. Not so complicated as ancient Egyptian Hyroglyphs but it's just down to the designers maths. Interesting video, Cheers.

Valve job, deck the head, deck the engine reset the valves, me rings, con rods, alkaline wash the whole engine in a shop washer. Engine will be pristine

[@therestorationshop]

Yes, that's just what we did. 100 over, decked, valves, new rods, rings, pistons, etc. Basically a brand new engine. I owe a debit of gratitude to John Cobb a 3rd generation engine builder that knew exactly how to do the work. Old School engine building in the 21st.

Elements of A series architecture.

Would have been nice to see the engine after being cleaned up and machined. And being rebuilt. Oh well

[@therestorationshop]

Yes, it is disappointing that several times I either had camera transfer issues or just forgot to get things setup for recording. The recording isn't at all "normal" to me yet but I'm working on it and should make some progress. I've gotten new equipment recently that will help.

[@ziggnutt1]

Please turn up your record volume. I have my laptop volume maxed out and can barely hear you. I love watching your progress but would love to hear the audio.

[@therestorationshop]

Thanks for the input. I'm working on getting better audio recording as well as speaking better.

Do the "T" marks line up only once when No.1 Cylinfer is at TDC ?

[@therestorationshop]

Sorry but I don't remember the specifics. I believe there are two parts on the chain/sprockets that are both aligned when at TDC.

[@andrewgardner9615]

What series engine is it ? It has elements of Austin /Morris A series

[@therestorationshop]

The car has the 1250 XPGA engine and does share design elements. The MGA engine is also similar.

[@andrewgardner9615]

Cheers from UK-There seem to be more MgTds over the pond than here!Probably all rotted away.Hard to get specific figures on"How many left" ukwebsite as it seems to also include TFs.

Is there no part 4?

[@therestorationshop]

I just got a new camera so I will be making part 4 very soon.

[@barnclebill6333]

Do the parts that you ordered come from England? I have heard that orders from the USA have a low priority. Is that true?

[@therestorationshop]

Some parts do come from England but I ordered most parts through Moss and they tend to have a fairly significant stock. In today's pandemic world I can only imagine what it is like getting parts from anywhere. I should what I need to get the car finished, except for time, of course. I've yet to find a supply of that!

[@barnclebill6333]

Thank-you for your quick response. Great job by the way.@@therestorationshop

How much did it cost to restore the engine

[@therestorationshop]

I spent just under $900 at the machine shop to have the cylinders bored .100" over, crank ground/polished at .010" under and the head cleaned/valves/spring reset, etc. I probably spent another $1000 on pistons/bearings/gaskets/etc to put it back together. The carbs were in good shape and just required the rebuild kit plus a reamer. I'd figure $2500 if I were to do another one. Obviously the only labor in that is the machine shop guy... I did the rest. Camshaft and crank are very expensive so I was fortunate to only need a light grind and polish.

[@sams244]

You guys not showing hands of working only lecture .this is not good to see.

[@therestorationshop]

I plan to get another camera that will record longer and I'll mount it to the side and have it film the actual work.

[@davebarrowcliffe1289]

You sound worried to death mate... Are you sure this line of work is for you? 🙂

[@jerrybaird2059]

Unfortunately not a quality presentation.
