Belt Drives

Be sure that the diaphragm spring retainer has the flat side facing away from the bike, and the beveled side faces the spring.

Be sure that the pressure plate is sitting flat against the last steel drive plate and is not touching the mainshaft nut.

Be sure that a steel plate goes in first and a steel plate goes in last before the pressure plate.

Be sure to check the diaphragm spring attitude by placing a straight edge across the face of the spring. The spring should be slightly convex with about .010 to .025 of daylight on both sides of the straight edge. On higher performance applications set the spring with .035-.040.

Be sure the belt has approximately ½ " to 1" of total free play.

Enclosed belt drives need to be vented to ensure longer belt and clutch life and the more venting the better. We recommend the TC-028-C inspection cover and the TC-020-C derby cover.

Always check the following prior to running an enclosed belt drive:
