Important Sprocket Information

Supplemental instructions for the new style sprockets (2003 and later)

To combat bushing and bearing slippage, the Bully clutch sprockets have been redesigned.

The 12�s and 13�s now have a bushing retaining ring in the base of the sprocket. To make room for this ring, the base of the sprocket was thickened, and the standard thrust washers (part #098-112) have been replaced with the new #098-113 thin thrust washers. To use this bushing retaining ring, the 12 or 13 tooth sprocket should be pressed into the drum first, and then the ring may be installed. To change sprockets, first remove the ring, then push the sprocket out of the drum.

The 14 through 21t Bully sprockets also use the new retaining ring to prevent the bearing from slipping out of the sprocket. The sprocket also has a "lip" in the base to prevent the bearing from slipping inward toward the clutch. These sprockets also have been thickened, and require the use of the new #098-113 thin thrust washers.* In addition, it is now necessary to always use the #098-013 outer thrust washer with these sprockets. It will seat down nicely on the bearing retaining ring, and allow the proper amount of endplay. These instructions also apply to the 15, 16 and 17 "skip tooth" sprockets as well.

Bully bushing type sprockets (12 and 13 tooth) use a bushing of bronze material. Use of other sprocket brands with a brass bushing may cause immediate and catastrophic failure of the Bully clutch.

Damage to the Bully clutch caused by the use of a sprocket with a brass bushing is the responsibility of the consumer.
