REMOVE 1.remove the drive belt by lifting the tension arm with a ring spanner. 2.undo the cas (crank shaft sensor) balancer bolt and washer (if u need use a pulley remover) 2 get 2 the cas! 3.remove the wiring connection from the cas then the crank sensor bolts and sensor (sorry got no pics as I'v got no cam)!!(inspect cas 2 c if any damage and also chek the rings on the crank shaft balancer 4 damage! INSTALL 1.replace the cas and tighten bolts (torque bolts to 20-40Nm 2.loosen sensor adjusting bolt and replace the crank shaft balancer bolt.(torque bolts to 270-325Nm 3.place a spec feeler gauge between the outer crankshaft bal ring and the cas!(the gap between the cbr and the cas should b 0.50mm)then tighten sensor adjusting bolts(torque bolts to 4-5Nm) 6.plug in the loom and put the drive belt on and hey presto that should do it !! And as said in previous posts I take no responsability 4 damage caused while these repairs are being made good luk with it and let us know how it works out!!!che trizo;P
