Ariens friction disc # 00300300 or Stens 240-394 I get mine at Oreilly Auto Parts # 7-04211 for $15 and they come with a lifetime warranty. I've had no fitment issues or operational complaints. You will likely need to call or drop in and have one ordered from the distribution center in your area as they usually aren't stocked in stores.
Still working on the belts. Original numbers according to your serial number.
Auger belt 07210800
Drive Belt 07209800
Hi Thank You 72098 belt (3/8 X 33) was listed at Ariens Parts store as 07232100 I am worried it may be an error or wrong size.
belts are listed this is 7hp 008001 serial that makes a difference 2 models that year for 7hp. Not sure what is different.
