Thanks, yes, that sounds about right, there are two in there, back to back. Since our exchange the other day, I went out to remind myself what it's internal workings looked like.. Mine also contains a shim (like a blank washer), not sure whether an original fitment or fitted by the previous owner to adjust the clearance / belt alignment at some point.
In any case, the assembly hasn't given any trouble in the last twenty-plus years of ownership..
They're a very nice machine – and pretty much everything that needs to serviced or maintained is easy to get at – one thing not to be neglected is cleanliness & oiling of the cross- & top – slide feedcsrew – the threads that receive these are cut directly into the metal of the respective parts and so a little attention paid to keeping these in good order will pay dividends in the later life of the machine.
