lazer zx gearbox help

[rob m]

hi all, i have just finished stripping cleaning and re building my lazer, i think its a zxr but not 100% with that, the part i need help with is the assembly of the main shaft. ive assembled it from memory.

starting from the spur gear side, i have......

lock nut
limiter coller
4 wave washers
guide plate
slipper plate
spur gear with balls
slipper plate
rear drive hub
drive pulley
pulley flange
8mm o/d x 4mm i/d 1.5 thick washer
thrust bearing
8mm o/d x4mm i/d 1.5 thick washer
E ring
drive pulley
pulley flange
shim
front drive hub
limiter collar
lock nut

hope all this makes sense. the part im not sure about is were i have put the thrust bearing between the two washers. i have downloaded a manual and no thrust bearing mentioned, just a collar. but i don't have a collar that fits. so if anybody can point me in the right directionwould be much appreciated.
thanks, rob.
