In reply to a message from abowie sent Wed 8 Apr 2015:
OK, mystery solved. I do have a later pulley. After reading all
of the various comments-and let me say that the is the real
value of this forum.
Some time has passed since I started this project, fitted the
chains and got to the point where things needed to be adjusted.
Well, actually, it’s been years. Other things have intervened
and this project just was not high on the list. When I started
this project up again I reviewed my notes and pictures and my
manuals. Unfortunately I didn’t have a good enough shot of the
engine to see what I really needed to see, and that is that
there was a timing indicator bolted to the side of the front
cover. The mention that the timing indicator had been moved to
the side of the engine sent me thinking. I went back and pulled
the box with the little baggies that I have stored away with
the bits from the engine and sure enough, in the bottom of the
bag I found the indicator.
Back to my mechanic with new pics.
The thing that was throwing me off was that the pan also has an
indicator bolted to it, although it was bent down and I
remember straightening it. OK, so once I temporarily put the
2nd indicator back on to the side of the engine and made sure
that #6 was at TDC, everything lined up and I took pics. My
mechanic looked at the pictures and said that it is right on
point. Yes, I do have the exhaust cam running a bit late and
yes, I will want to adjust it, but in the end, the engine is
basically in time.
I feel so much better now!
So what this means is that this car came from the factory with
both timing indicators. The difference is that later engines
are fitted with a different balancer, and the way to tell the
difference is that the position of the timing scale stamped on
the pulley face does not line up with the woodruff key. My
mechanic said that the woodruff key slots on both the crank and
the pulley cone for all 4.2’s should be straight up and down
when the #6 is at TDC. At that point the cams should be
adjusted with the cam tool.
So, mystery solved-and thanks for the comments because I would
have never thought to search the parts bags for a second
indicator. And, if I had tried to time the engine based on the
pan indicator alone I would have destroyed the valves. This is
good stuff to know!
