Exactly what it should have been
It was OEM, worked great. My only real issue was I bought the part and 4 extra hex head bolts, when 4 came in the box with the part. Shipping was a bit slow, but not unacceptable.
Overall, a great repair.

This repair was very time consuming so I will try to compress the repair, I have a Weedeater One Lawn tractor. The drive pulley that connects to the engine had split and spun on the crankshaft. The engine had to be removed. This was the reason for all the intensive labor as the mower, belts and a lot of bolts needed to be removed. The pul

When the pulley split it took a chunk of the crankshaft with it leaving only a small amount of metal for the pulley keyway to engage the crankshaft. Rather than take a chance I drilled the crankshaft and pulley with a one quarter inch. drill and installed a hardened bolt to secure the pulley. So far so good. Take a lot of pictures when you disassemble the mower so reinstall is easier.

I removed the deck completely from the craftsman lawn tractor. Removed all damaged parts from the mower deck with the necessary tools making sure to take a cell phone picture prior to disassembly. FYI, I did not realize the mandrel assembly was not threaded at the 4 points where you attach the mandrel to the deck with the washer head scre

This project was a little more time consuming because the old mandrel assembly had sheared off at 3 points and the broken pieces under the washer head screws were troublesome to remove. Liquid wrench helped with the removal though. FYI, make sure you don\'t forget to put the spacer on top of the mandrel before you attach the pulley to the top of the mandrel. All new parts went together very nicely on re-assembly. I re-attached the deck to the Lawn tractor. I started the mower and it worked flawlessly.
Remove belt and pulley. Remove blade from inside the deck. Remove three screws that attach the housing to the mower deck.

Tip: If grinding off mandrel assembly please realize the mandrel pulley is to large to fit through the hole in the mower deck and enough of of the bottom part of the mandrel assembly will have to be removed to allow the mandrel assemble to slide out from top of the mower deck.
