many guys don,t understand that on these multi key timing sets there areTHREE different letters,
on the crank gear and three matching keyway slots.
0 on the cam gear gets lined up with 0 on the crank gear, if the 0 crank key slot is used to index the cam at TDC
0 on the cam gear gets lined up with R on the crank gear, if the R crank key slot is used to index the cam at 4 degrees retarded from TDC
0 on the cam gear gets lined up with A on the crank gear, if the A crank key slot is used to index the cam at 4 degrees ADVANCED from TDC
one of the more common screw-ups is forgetting to lock the three cam bolts with either a lock plate with tabs that bend up and prevent the bolts holding the timing gear to the cam or useing safety wire, on the three bolts, LOCTITE thread locker on the threads sure won,t hurt either, because that gear takes alot of shock loads constantly durring shifts and its comon for un-secured bolts to eventually work loose
