Okay. Picture came up this time.
On the upper left sprocket (rear balance shaft), the white paint mark is
over a depression in the sprocket. This should be aligned with the
cut-out in the oil pump casing to the left of the sprocket.
On the crankshaft, look at the cutout in the plate. This aligns with a
pointer on the oil pump case. I cannot see the pointer in your picture.
On the lower right sprocket (oil pump/front balance shaft), the dimple in
the outer circumference aligns with the pointer on the oil pump case at
about 10:30. This sprocket, however doesn't turn an integral number of
turns with one turn of the crankshaft, so special procedures are necessary
to time it correctly. If it's 1/3 of a turn off in either direction, it's
probably timed correctly. To time it, turn it a little away from the
pointer. If it tends to return, it's timed correctly. If it tends to
keep turning, you'll need to rotate it one revolution to time it
I don't see the plastic pieces in your picture, so still no ideas there.
