Re: Hotpoint TCM570G – Tumble Dryer belt tension pulley
should be part no C00113879
this is a condensor dryer so you have to remove the fan cover in front of the motor and remove the fan to get at the bolt holding pulley can be a bit tricky to fit since belt is elastic but if you fit back bolt first do not tighten just put in a few threads you can use the pulley as a lever to tention belt pulley then hooks into motor and you can tighten up
hope it helps plug out first
