Hi, HeVi,
Many thanks for the advice but could you please clarify...

I'm sorry but I'm a bit thick ;>)
So would you please explain in more detail...

You say >>
the problem that u refer is on the main motor gear.
remove that gear and turn it back.u have to expand a litle bit the hole.
That will solve your problem.
<<

The main motor is in the middle of the cogs, (on the left-hand side of the machine)

The motors drive shaft has a small (about 6mm dia) white knurled cog on it .

So, do you mean this cog ?

If so, can I replace just this cog ?
Or will I have to buy a complete new motor and cog ?

And, what do you mean by...

Thanks
