gears not engaging

[shanesmith]

Hi everyone, hope you are all well 
I was traveling home today on my 2005 px125 and all of a sudden the gears wouldn't engage fully they were engaging only a little so had to push it home ( lucky i was close )
when I got back I checked the cables but while it was running it was making the rear wheel rock 
I don't know if i need to take it in so any help would be appreciated 
thanks

Hello there you need to jack up back wheel and rock it at twelve oclock and six oclock position to see if there is any play.the nut in middle of Hub should have a locking tab so to stop nut comming lose but check to make sure let us know how you get on cheers alan.

Hi alan
thanks for the reply
there is a little play in it but not massive
even when i put it into gear it doesn't stall just keeps ticking over in every gear with only a slight side to side movement of the rear

HI
the rear hub has a bit more play than first thought, but I couldn't tighten or loosen so Ive sprayed it with penetrating spray and I will try again tomorrow
i did start it up and the the driveshaft was turning, so either needs nipping up or its the hub or drive shaft?
I'm also not sure if it one of the Fa italia hubs

Hi
It was a Fa italia hub and the previous owner had only used one washer so the nut had come loose and the hub had worn out fins
