I am replacing all idlers and need to install new clutch bearing, system is charged and working r12, so I want to remove a/c clutch on car, I have everything apart and center bolt is out and have tried a puller kit but it didn't have the correct lug and center bolt to remove, I have not done this before and can use some advice on the correct way without damaging it, I believe it's a Pitts unit, thanks in advance,Pete
