I have just taken the side off my dryer and saw that the belt is fine but the tensioner plastic wheel is broken.
Can I get this part or do I have to change the whole motor.

Don't know what model it is or where you live (could be on a boat in the middle of the Pacific for all we know.) Suggest you phone your nearest Indesit parts shop, give them the model number and ask them.
