How to Select a Belt
1. Determine the Series Type. (Comet Model Number)
2. Measure the “Outer Diameter” (O.D.) of the driven pulley on the jackshaft.
3. Measure the “Center Distance”; which is the exact distance between the center of the engine crankshaft and the center of the jackshaft or secondary shaft. Must be precise.
4. Use the two measurements; the driven pulley outer diameter and center distance measurement to determine the correct belt part number from the relevant chart below. Should your machine’s center distance fall between the center distance settings listed here, select from the two belts, the one with the larger outside circumference (O.C.) for best wear and to avoid machine “creep” during idling.
How to Install the Belt
1. Remove the bolt and any keepers from the end of the engine crankshaft, and take the outer half of the clutch off.
2. Clean the clutch. Make sure both components are perfectly aligned.
3. Flat washers and shims are used as spacers.
4. Do whatever it takes to align both components so the side of the belt won’t wear down prematurely and litter the system with belt debris. Align the sprockets so the chain will stay on.
NOTE:
-If you can install the belt without taking the clutch apart, the belt is too long.
-If the system is ‘eating belts’ do not install a new belt until the problem has been corrected. A damaged belt is the symptom of another problem.
-If the original engine has been replaced, some machines may require a different belt , which usually changes the center distance, or, if the original driven pulley has been replaced with a different outer diameter component.
