Yup! that's the part! I dodn't check if that's the right part for your particular machine... but
Bloody hell!!!!!! Dick Turpin, at least had the decency to wear a black eyepatch before emptying their wallets
Now, before you get ambitious.
If you could get access from the front, the guys on here would have told you so!
when the spider goes, as you have established, the clothes-drum wobbles around hitting the tub...the heater is inthe gap and, unless it's recessed, the drum front edge saws a slot in the heater which is now U/S
You will likely find that the drum is RIVETTED to the old spider....you would have to cut/drill/grind away the rivets without damaging the (wafer-thin) Stainless
Oh, and you'll need stainless bolts/nuts/lockwashers (available in small packs in some sizes from Screwfix, budget £15 or so )
then you stil have the bearing/seal kit..
My advice, your'e kicking 5hit uphill with Indesit......if you really want to repair a machine ,for the challenge, pick up a non-working Bosch or Zanussi (Miele are great but parts unobtainable on the open market and would bankrupt you)
off Fleabay... my last Zanussi cost me £15 by the time i'd collected it....fixed the doorlock but it had fried the main board...transistors/capacitors/resistors are not a problem but ONLY they have the EEPROM , without which you're stymied!
research this site, you'll then know what is a reasonable and repairable machine.
It won't be labelled Indesit unless it's already over 20 years old
(in which case all rubber will be perished and unobtainable!
old enough for wisdom, young enough to be compos mentis.
