Inside this document
This dedicated April 1949 bulletin presents an ordered diagnosis for slow or inoperative Studebaker windshield wipers. The illustrated checks cover blade speed, arm pressure, cable routing and lubrication, tensioner adjustment, motor connections and vacuum measurements at the engine and fuel-vacuum pump. It distinguishes the earlier cable-tensioner arrangement from the automatic ratchet type fitted to 1949 models, making the complete issue useful for restoring the original vacuum-wiper system.
Subjects covered:
• windshield-wiper speed diagnosis
• wiper-arm pressure
• cable and tensioner adjustment
• vacuum supply testing
