156 2.0 TS

Orientation of crankshaft and balancer shafts ?

I recently removed and then put back on the belts on a 2.0 TS. I was checking the timing on the camshafts. The marks on the balancer shaft belt were gone (worn), so I used the illustration on the attached image (out of Gaaza82's guide): camshaft mark to the left (90 deg from up), and balancer shafts marks up at 0 deg. I have some doubts left, because in this camshaft position the mark on the aux. belt pulley is not aligned to the plastic cover mark and the 1st cyl. piston is beyond its TDC.

Any opinions on what is correct?

Well correct would be either marking the belt and pulleys before you removed it, or fitting a new belt.

Forget about the timing marks on the belt itself - focus on the shafts... get the TDC on Cyl 1, the pulley on the crank will be at 9 o'clock, Balance shafts should be at 12 o'clock

leave the balancer belt off unless you have one with timing marks.
