TY80 Gear Shift Question

Featured Replies

Hi all,

I've just rebuilt the engine on this 1980 TY80 and just put the crank cases toghether again along with clutch basket pushrod, primary gear mesh and shift mech.

I have a couple of questions I hope you can help me with

1) The clucth basket outer will rotate anti clockwise which drives the crank clockwise but when I try to rotate the clutch basket outer clockwise it will go 1/4 turn before stopping.

Is that normal ?

2) Should I be able to use the gear shift mech to select all gears by hand at this stage ?

Thanks in advance.

 

 You did put it together in nuetral? You should be able to select gears by rotating the countet shaft sprocket. When the basket is rotated backwards is it the Kick start thay is stopping it?

Nope I dont think I did assemble in neutral. 

Yes when the basket is rotated back the gear on the kick starter seems to engage with the idler gear and thats when it binds.

I think that is normal ?

Im rather concerned about gear selection now. I hope I dont have to split the cases again to fix ? Any advice would be great.

Thanks

Sorted - after install and start up the gears work well.
