I have searched, but was unable to find the answer.



I understand how the CAS is installed with a regular main pulley with the yellow timing mark, which is 5 ATDC.



What I am having a problen with is the RB main pulling is described as follow by RB:



Timing marks are provided at 10¡, ATC (0¡), and at 10 degrees and 20 degrees BTC.



I am not sure of which one of the four to use.



Does anyone know how to do it?



Thanx

put the pulley on the 0 mark. if you're in front of the car it will be the second to left mark. ok now put the motor half way to the next left mark, this is close enough to 5atdc. engine spins counterclock wise if you're standing in front of the car.



now put cas in so that one of the 2 "big" teeth is in the little hole in the cas cover

Line up old an new pully and make your own marks and use some red and yellow paint. https://www.nopistons.com/forums/pub...1047683473.gif
