Why would the part manufacturer pay the labour charges of fitting it?They might argue you would have to pay someone to fit unless doing yourself anyway.
They might also say that any obvious defects should have been pointed out by the garage upon fitting,and rang to notify you.
They might say you could only claim for the additional expense of having the clutch removed for inspection,and then the cost of a replacement one refitted.
