Tom,
Did you look at the crank pully timing degree wheel when the cam marks were aligned?

If you didn't check, you;ll need to re-align the cam tower marks and cam mark - then look at the degree wheel on the crank pully to read the degrees away from Zero it is.

Sorry if I didn't make that clear ---

Larry T, thank you.  My cam lobe on the cam shaft the first one closest to
the radiator #1 cylinder, was sticking out to the right almost 90 around 90 degrees at 3:00. (when standing and looking towards front windshield) when
the marks matched up perfectly.  Was in the same position as the photo in
the MB manual so I assume we are in good standing./Tom

Hi Tom,
   As the engine rotates - and it must *only* be turned in the normal
direction of travel, BTW - you'll see the cam lobes turn and alternately
open/close the valves. When both of the high parts of the cam over #1 are
pointing more or less up, it'll be on TDC - but the scale on the crank is
the final authority. Once close, you should be looking to get the mark on
the cam aligned with the notch in the cam tower closest to the radiator.
But, even if you miss the spot by just a little don't be tempted to turn
the
engine backwards to the mark - just crank the engine over again and watch
the cam until the mark is close.  It can be frustrating as often the
compression will not allow the engine to stop at the proper point.  Just
be
patient.

   Once you've done it once it will seem very easy.

   Good luck -

why do you need a dial indicator to check chain stretch?  You simply
rotate the engine around till you line up with TDC on the crank, then
slowly turn it till the lines on the cam shaft line up, then look at the
crank and see how many degrees you are off.

Bought
a dial gauage and want to test the stretch and timing while I am in
there.
Anyone now exactly what size threaded piece with thread size I need or
can
describe it to bolt into engine to hold the
dial indicator.  I scimmed through the 616 and 617 engine manual
quickly
MB
said something about this makes sence
and would please like to know what piece I need.  Thanks and happy
Friday
