We are done with 24 harvest but picked up the pulley that we ordered from the local CIH dealer. The Cummings pulley failed 2 years in a row. The CIH pulley is definitely thicker in the face area just by feel. 3 ml to 4 ml. CIH part #is 84244661, $148, the Cummings pulley was $150 so less than I thought for the upgrade. Bolt pattern and dimensions look identical. Leon B MO  ------------- Uncle always said "Fill the back of the shovel and the front will take care of itself". |

| What numbers are stamped in the pulleys? I’m sure they both are Cummins parts. |

| Leon does yours have the AC drive pulley on front of that pulley? Had shield off yesterday to blow out radiator and seen a pully stacked on that pulley which is shaped to fit over and back on the tapered part. Looks like it would reinforce that pulley. At least that's what I think I saw. |

Yes that is the number that is stamped on to the pulley. And yes the pulley for the air conditioning sits in front of that pulley. Also I have been making sure to blow out the water pump and fan pulleys when I clean the machine in the mornings.

Just a sidenote. The box the pully came in said CIH Industrial. Leon B MO ------------- Uncle always said "Fill the back of the shovel and the front will take care of itself". |

My R62 did that a few years ago. I didn't notice if the new pulley was thicker than the old one. Now the pulley has about as many hours of use as the original pulley so pre harvest I pull the fan and check for cracks but probably couldn't see them forming. Steve
