V-BELT SET 7W5228 - Caterpillar

Impellers and seals require periodic inspection. Impellers have a service life that is limited. The service life depends on the engine operating conditions.Inspect the components more frequently when the pump is exposed to debris, sand, or other abrasive materials. Inspect the components if the pump is operating at a differential pressure of more than 103 kPa (15 psi).There are different types of pumps. Some pumps will have a cover that is bolted to the main pump body. Some pumps will have a clamp that holds the front part of the pump body to the main part of the pump body. The cover or the front part of the pump body must be removed in order to inspect the pump.Pumps with a Cover
