Howard HR20 Rotavator Clutch Disc - PN 624 420

[gregbbff]

We were using our Howard rotavator this morning and burnt the clutch up in it. While tearing it apart we noticed heat discoloration on the clutch disc, part number 624-420. It's a conical disc with female splines that interfaces with the rotavator gearbox. Our local supplier says this disc is discontinued from a mass production and supply stand-point. Does anyone know where I could find one?

In the meantime, we put new clutch plates in and are sending in back out to work, but it'd be nice to be able to replace the disc if possible.
