Checking V-Belt Tension When servicing the engine, care should be excercised to keep oil and grease off the V-belt; oily V-belts should be washed in a soap or detergent solution and then thoroughly rinsed in clear water although it is always of advantage in such cases to install a new belt. V-belts contaminated with oil or grease for any length of time are usually no longer serviceable and must be replaced. When correctly adjusted, the V-belt can be deflected by 15-20 mm (5/8 - 3/4 in.) under slight thumb pressure applied midway between both belt pulleys. The belt should not show any signs of wear such as frayed edges or split flanks. |
