Essex Timing markings

Post by MikeyBikey » Wed Apr 18, 2012 11:13 am

Got this out of the repair manual for the essex. It's the timing markers on the front plate. Would it be fair to say the picture is incorrect. The main picture says each peak to trough is two degrees. The smaller picture says four. ??

I thought that the flat part shown as pointer no 4 was 14 deg and the first dip is shown by pointer 3 which would be 4 deg apart and is correct if I understand it correctly.

2 degrees of cam timing; 4 degrees of crank timing...?

That diagram comes from the autobooks manual. AFAIK the advance for the early Essex is 10 deg and the advance for the later Essex is 14 deg. Checking with the respective Reliant manuals suggests that the inset in the above diagram is correct (i.e. 10 is the last peak and 14 is the last trough). counting back to TDC that obviously doesn't quite work, if you assume all the "legs" of the mark are identical, but maybe they're not? perhaps the first peak is only 2 deg?

I've just amended the picture to include the footnote stating pointer three is 10'. pointer 4 is 14'

This seems to clarify it. The pictures in the manuals are a bit ambiguous.

Ian, your picture is different from the one in the Se5/5a manual, which shows the 10 deg mark on the second peak? Also your diagram shows the first part as 6 deg, surely that's odd, as that's TDC? I though all engines would have an indication for TDC (that's how I've always regarded it) or am I going mad? :?

I discovered the picture in my earlier post when I found that there were discrepancies with the manuals. The picture MikeyBikey posted from the Club manual shows something different in the overall picture and in the enlargement. The overall picture shows the leading edge as 14BTDC and the central valley as 10BTDC but the enlarged area shows the leading edge as 14BTDC and the first ridge as 10BTDC.

The official Reliant blue folder manual has annotated photographs in two places and seems to indicate that you time to the first ridge for 10BTDC but in the text it says 10BTDC is the lower edge of the timing boss. This is for the earlier engine.

Is there a difference between the timing bosses on early and late timing covers?

BTW, I have found no reference anywhere to TDC being indicated on the timing boss at all. I think one of us will have to check this out with a stick down the plug hole to find TDC and see where the pulley mark is.

It really is a :w

And to add to the confusion Josh's 5a and my old 5a have/had no marks on the pulley wheel :?

Well, I think I have the answer, now I've had time for a bit more research. The only problem is I'm having trouble operating my scanner wearing this straightjacket, but the men in white coats will be along shortly with my medication, then I'll post the result!

Right, here we are. The definitive answer (probably........ :w .). I sit here surrounded by Reliant manuals, but I also have a genuine Ford Capri manual, so I went there in search of an answer. What I found was as follows:

So it looks like your diagram is correct Ian, and we don't have a TDC mark :oops: It also confirms the ambiguity in the Reliant diagrams. I suppose since I've always timed by strobe to the 14 deg mark, it's absence hasn't made a huge difference over the years, though I must admit I'm surprised.

I think I'll move this thread to be a sticky for the sake of posterity. :)
