Centrifugal Clutch, 5 / 8 Inch Bore 11T No.35 Chain Clutch, for 2.8Hp and 97Cc Engines, for Go Karts

Where do you oil the clutch? Behind the snap ring, next to the sprocket teeth at of the clutch. There's an internal bronze bushing behind the snap ring that requires lubrication and it's up to you to put it there each time. It's a good idea to oil the chain at the same time. If the chain gets kinky from lack of oil it should be replaced before it damages the clutch sprocket. A new chain is cheaper than a new clutch.Habits That Can Ruin A Clutch - Keep Your Machine Safe.1. Driving too slowly: A clutch starts to engage around 2,000 rpm and will lock up around 2,600 rpm.2. Short stop and go driving: The longer you drive at the better off it is for the clutch, because it gives it a chance to cool off before engagement. 3. Driving with the foot on the brake: This is a problem with new drivers that are unsure of themselves.4. Changing the size of the tires: Putting on tires that are larger than what came with the kart will result in clutch problems.No larger than 15 inch tall. 5. Weight: A centrifugal clutch is designed to be to move a certain amount of weight.6. Gear ratio: The sprocket on the engine and on the rear axle should have a ratio close to 1: 6.(10 tooth = 60 rear sprocket)7. Restrictions: Don't try and reduce a go kart speed by limiting the travel of the gas pedal or by putting a restrictor in the carburetor to limit full rpm. 8. Don't put oil inside the clutch holes: The holes on the drum are to let the hot air out of the clutch. DO NOT SQUIRT OIL IN THESE HOLES. When oil gets in the drum portion of the clutch it will cause excessive slippage, which means undue heat will be generated.High Quality Go Kart Tractor Mini Bike Cyntrifical Clutch 5\/8 inch BoreAccepts 35# Chain (3\/8 inch chain pitch) 11 Tooth Sprocket Racing Centrifugal ClutchDesigned for Single Wheel Drive Karts with Tires no larger than 15 inch TallBi-directional operation, Easy to installBore diameter: .625 inches (slightly smaller than a DimeFits: Centrifugal Clutch 11 tooth, 5 8 bore, use 35 chain 2.8 97cc engine, some older 3hp enginesEngines with 5\/8 inch (.625 inch) output shaft with standard keywaySet Screws NOT Included.
