On the Citroen SM with 3.0 Liter Maserati engine and 3 speed automatic transmission, it is very important to remember this. If you remove the torque converter for repair, it’s possible when reattaching it to the engine to attach the torque converter to the crankshaft pulley in any one of four positions, only one of which will be correct.

Mounting the torque converter up in the wrong position will cause the timing hole in the bell housing to not line up with the timing mark on the converter housing.

To prevent this from happening, it is very important to set the position of piston No.1 of the motor at TDC . After you do this, position the converter so that the timing mark lines up with the peephole in the bellhousing.

Always remember to check twice and do once.

Take care of those Citroën SM engines they don’t make them anymore!

Later, Denis
