When installing the timing belt with the Kiggly racing tone wheel and AEM cam gears I have lined up the marks on the cam gears and held them in place with the STM cam gear holder. I have lined up the mark on the tone wheel (crank gear/kiggly tone wheel) as accurately as possible (the balance shaft drive gear with spacer plate that has the TDC indicator on it has been deleted due to the Kiggly tone wheel install).
After everything is lined up and the tension is set and the crank has been rotated 2 times the marks all seem to line up. However, after installing the timing cover and crank balancer the TDC mark on the timing cover does not seem to line up with the notch on the balancer, it is literally a hair off or maybe a half tooth 1-2mm from TDC.
At this point I lined the mark on the front cover to the notch on the crank pulley, removed the front cover and held the belt to the crank sprocket and oil pump gear with plastic clamps so it will not move. I repositioned the cam gears, set the tension, reinstalled the cover just to find out the notch on the dampener barely lines up to the TDC mark on the cover, its like 1.5mm-2mm off in the retard position. I hope this makes sense..
Has anyone ran into this?
I am thinking it is probably OK, due to the fact I cannot use the balance shaft gear spacer with TDC mark as a guide.
Sorry for the long thread.
I appreciate all the help!
