The centrifical clutch came installed on my 1572 from the factory. I ordered my 1572 before any of them hit the dealers floor. They didn't even have literature for them yet. I believe mine was one of the first ones built as I found there was some parts incorrectly assembled on it from the factory. The centrifical clutch can be a problem if the bronze centering bearing in the rear yoke becomes worn, then the whole assembly will not run true to centerline of the shaft and be off-balance, causing a lot of vibration. I've have to replace that rear bronze bearing 3 times.
On my 782D, I do not have a centrifical disconnect clutch on it. A kit was available to add it at one time. I've been toying with the idea to remove the clutch on my 1572 and replace it with a straight shaft like on the 782D to reduce problems.
