The outer guard sheave on the crankshaft wheel has a notch that aligns
with the protruded index line on the front of the engine. The dot on the
camshaft aligns with a notch cut in the front of the cam cover. If your
distributor is in the back of the head the dot on the jack shaft pulley
is irrelevant otherwise use the single line markings on the new belt to
stablish the correct location.
Install the belt starting at the crankshaft, around the jackshaft and
around the camshaft so that all the slack is on the tensioner side.
Slacken the nut on the tensioner and pry it against the spring all the
way to the loosest position and tighen the nut (Probably shuld be the
first step). Use a clothes pin clamp to hold ther belt stationary on the
cam wheel and slide the belt over the tensioner pulley. Loosen the nut
and let the the tensioner find its own center. Tighten the nut. Check
your timing marks for proper alignment. Install the crank bolt and turn
the motor through 2 or four revolutions to be sure nothing is binding.
Inspect the timing mark alignment one more time. If there was too much
slack on the left side of the motor (right side as you face it) the
tensioner will pull the crank pulley clockwise as you face the motor and
your marks won't line up.
In four cylinder history, motors set up with the crank on TDC and the
mark on the cam gear or sprocket if a chain driven motor facing each
other. This would be #4 compression/firing. But when you put the mark on
top, since the pulleys are relatively far apart using this method is
difficult, so a mark was placed topside to facilitate set up. In order
to do this the motor had to be turned another 180 degrees to put the cam
mark at the top, hence the motor sets up on #1 compression/firing. I
haven't ever seen a bentley manual so I don't know what they are talking
about with 11 o'clock and such. The marks make a straight run down the
center line of the motor.
So I guess the short answer to your question is, "yes."
The goal when driving is to miss the maximum number of objects.
