alexb Posted August 28, 2015 Report Share Posted August 28, 2015 Hi all. I have a 1971 Mk4 Spitfire which had a replacement engine fitted some years ago. Just trying to ID the engine number just to see what it came out of in the 1st place. Also trying to suss out the TDC marker so we can get it timed up correctly. All it has is a pointer and not the plate marking out the TCD +/- The number is: ( i think.) UUECLJ061 Any ideas ?. I guessing it was prob re-stamped by the company that re-furb'd it perhaps ?. Cheers. Alex. Link to comment Share on other sites More sharing options...
JohnD Posted August 28, 2015 Report Share Posted August 28, 2015 Useful list of Triumph engine numbers here: http://www.triumphspitfire.com/enginenumbers.html The number you list just isn't in the usual format of two letters and then numbers, and "UU" isn't one of the two letters, so a rebuilder's number more like. But if the number is in the usual place, then they must have overstamped it. Can you see any trace of what it was before? Could that first letter be a 'G' from the Herald series?

Pete Lewis Posted August 28, 2015 Report Share Posted August 28, 2015 Thats def a recondioners number , its not a triumph suffix so you have a single pointer on the timing cover ?? but no marks on the pulley/damper ring ?? pete Link to comment Share on other sites More sharing options...
thescrapman Posted August 31, 2015 Report Share Posted August 31, 2015 There will be a little tiny hole in the pulley at TDC. The it is 1 or 1.5mm per degree round the outside. Measure the pulley circumference, it will be about 240 or 360mm Link to comment Share on other sites More sharing options...
