Thanks Dave, looks like it won’t be a viable repair then as the seal from Connect is £9.40 + VAT special order and the spider is megga bucks. It is a drum out the top job so I would have to charge extra labour anyway.
Customer decided to get a new machine so I took the Bendix for reconditioning. I’ve not stripped it yet but did take off the pulley and the outer bearing is a 6204 i.e. 20 x 47 x 14. So it looks like it is the standard Zanussi setup. Electrolux group always were bad for giving the wrong information on bearings, spiders etc. 🙁
