best to make sure the gears are aligned,,, don`t just whack a thrust plate in & tightene everything up,,, you should (at-least) straight-edge the gears to make sure they`re "in-line" with eachother
There are shims on the crank to pack-out the crank gear to suit the cam-gear position,,, add or reduce shims to aligne the gears
However,,, we prefer to trim the cam sproket to suit (in a lathe) ,,,--> both the abuttment to suit the alignment of the cam gears & then also the next shoulder to suit the thickness of the cam thrust , plus 3 or 4 thou for end-float.
this way there are no shims to break-up & fall out,,, sometimes people leave the shims on the crank when sending the crank for hardening & of course then the shims are way too brittle & can crack-up & fall out, leaving the front pulley loose & flog the key-way on the crank & pulley & you only find-out when the pulley comes out far enough to hit the cooling fan & by then it`s all too late, fan is busted, radiator may be smashed, front pulley ruined, crank-key-way stuffed & possibly the center main bearing shredded because the harmonics went hay-wire & ruined your main bearings too
if you`re not sure what to do here then please contact someone who knows what they`re doing to help you before you chew the side of the cam gears & stretch cam chains needlessly.
OK???
