they get it from us.
Similarly with the 5471 motor, some sellers are listing that are suitable for all earlier X models, which again is absolutely not the case as you have just read..It is also important that the correct belt is fitted with your motor, and that the motor has the correct pulley cog.

Again, they all look virtually identical but they are not.The pulley cog matches the belt.Make sure the teeth of the belt mesh perfectly with the motor pulley cog and not.

Early motors, being the Ametek Lamb usually have the 5379 belt.Later motors usually have a 5463 belt..

If you are fitting a new Domel motor into an application that has the belt 5379 you need to swap over the top toothed drive pulley cog from your old motor (it unscrews)..
If you fit incompatible drive belts to a new motor or incompatible pulley cogs to your existing belt, your Sebo vacuum will soon snap or shred the belt..That’s hilarious!.
A piece of £99 Chinese junk at number one, above the Sebo?That’s like putting a Lada above a BMW.
At ninety-nine quid, you get what you pay for.A cheap piece of Chinese tat masquerading as a British brand that will be in the bin after twelve months.
