Just stripped and refurbed a Royal 994 upright. I noticed contrary to all my other Royals that there were no cardboard spacers between the nozzle and fan case. This led me to question why these things exist? There is a rubber ring which fits in a groove on the nozzle and a matching circular "tongue" on the fan case. These nicely compress the rubber ring to form a seal. Add in one big fat cardboard spacer, and a thinner one and now there's no way this metal tongue and groove can function. I tried installing a pair of spare spacers, and it simply left a rubber ring capable of being rotated by hand.
The hole in the thin spacer is larger than the rubber gasket, but not so for the thick spacer.
Interestingly, the Royal 660 parts diagram which I have shows only one spacer, yet all mine except this 994 - where presumably the spacers were removed - have two.
