AEM CAS Trigger Disc 308760 User Manual

							 
**Cam / Crank Angle Sensor: AEM trigger disc MUST be used   
Discrepancies  have  been  observed  in  the  OEM  cam/crank  angle  trigger  discs  between 
model years and/or trim  levels;  to avoid  confusion the  Series  2  EMS  does not  support  the 
OEM Nissan trigger pattern. A replacement trigger disc is now included with every Nissan 
EMS and must be installed before attempting to start the engine. The following installation 
was  performed  on  a  modified Nissan  S13  240SX  with  an  SR20DET  swap so  your 
installation may  require  more or less  removal of parts,  but  the procedure for the  CAS  disc 
change should be identical. 
 
Tools/parts required: 
 Replacement trigger disc for Nissan RB/VG/VE cam angle sensor  
(AEM P/N 35-8760, supplied with 30-6601, 30-6602, and 30-6620 EMS) 
 8mm socket with ratchet 
 ¼ ”  flat screwdriver 
 No. 1 Phillips screwdriver 
 Red threadlocker 
 
WARNING: 
Failure  to  perform  the  following  procedure  correctly  could  result  in  permanent  damage  to 
mechanical  and  electrical  sensor  components,  which  could  result  in  engine  damage. 
Please read all instructions carefully before attempting this procedure, and do not attempt 
the  install  if  you  feel  you  may  not  be  able  to  perform  all  operations  safely  without 
damaging components. AEM will not be held liable for any damage that occurs as a result 
of these instructions.
