Cunmins 931a2 harmonic Balancer replacement

[Jericho]

Iam off station from home. Harmonic balancer outer shell with the serpentine belt grooves seems to be slipping forward from the crank portion. Shredded my belt.
anyone have a good Cummins , Napa. Orieleys part number for a replacement. ?
are all 6cta Cummins balancers the same ? Thanks in advance. Stopped until I can fix it Andy

Not all are the same. Some have larger OD and belt area OD. There should be a part number dot matrix stamped into yours.

Thanks Will. Good to know. I’ve been MIA for a few years. Glad to see you are still there and as always. Quick to reply and a good source of info. Again thank you sir. !
