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.

There is a grey bushing in the central spur gear hole. There is a bushing in the hub going into the motor plate. Theres two options between the layshaft pulleys, i prefer the thrust washer to a solid bearing but the bearing does work just as well. So for a bearing measure the inner thrust plare washers inner hole and also the outer diameter in mm's and then you should be able to find a bearing. Be warned you may find the bearing works better without the e clip on the layshaft

Rather than people trying to guess whether it's correct or not, here's the ZX-R manual.

Hi Welshy. I
Forgot to mention them bushings, They are in my build. have i done the thrust bearing part correct? With the two 1.5 washers either side of the thrust bearing? Thats the part im unsure about and is not shown in manual .
Thanks for the replys

The thrust bearing is not shown in the manual because it's not supposed to be in there. In yours all it is doing is acting as a spacer.
