WABCO MOTOR GRADER OPERATION 1960s CONSTRUCTION TRAINING FILM 63934

This 1960s color film is about WABCO Motor Graders (LeTourneau-Westinghouse) and made by WABCO Earthmoving Equipment, Peoria, IL. The film opens with motor graders in action along the side of roads, including a 440H. A closeup of mud rolling in front of the blade from the operator’s point of view is shown (:04-1:54). Preventive Maintenance. The Operator’s Guide is shown for the Models 666 and 777; the H and NH series; In-Line 71 Engines Detroit Diesel; Model 330, 330H, and Model 440. The WABCO demonstrators wears a white company long-sleeved jumpsuit and silver hard hat. He uses the dipstick to check the levels for the hydraulic oil, diesel fuel, and crankcase oil. He removes the radiator cap and checks the water level (1:55- 3:48). The air cleaner is unhooked and the tray emptied. He hand-checks the hose clamps. The individual battery cells are checked. The petcock on the fuel filter is opened and the fan belts checked (3:49-5:38). Tires are inspected and a tire pressure gauge shown. The hydraulic brake lines are checked, brake master cylinder checked by sticking his finger in and seeing oil on it, free travel of the clutch pedal tested based on the holes, and the hydraulic line checked for leaks. The page in the operator’s manual is shown (5:39-7:15). The moldboard boots and cutting edge are inspected, universal joints moved, and loose bolts tightened with a wrench. The page in the operator’s manual is shown (7:15-8:45). The seat and gears are shown from the top down. He makes sure both gear levers are in neutral, sets the governor control, turns the key, and the H-pattern gear shifting is explained. The operator’s manual shows the positions (8:48-10:10). The demonstrator gets in the cab of the LW-777. He verifies the engine shutdown control is pushed in, gears in neutral, starts the engine, and shifts the ground speed control to neutral. The power clutch brake pedal and accelerator/deaccelerator pedals are explained. The torque converter dipstick is checked. The engine shutoff level is shown (10:11-12:18). The 4440H is lubricated using a hand pump for some and a mixture of diesel fuel and engine oil poured through a nozzle. The points are shown in the operator’s manual. End play and anti-coast brake adjustments are made with a wrench. The oil clutch dipstick is checked (12:19-15:56). Basic Operations. The motor grader is shown in action, with the blade moving dirt. The scarifier attachment has 11 teeth that can be removed. The teeth are lowered into the ground and break up the material at those points (16:00-18:56). Bank sloping uses the blade adjusted to a different position via the lift links. The final bank result is shown (18:57-20:02). The steps to V-ditch cutting are shown. The motor grader is backed in high speed to the beginning point. The lift links are adjusted. A flat-bottomed ditch further flattens out the V-ditch cut, with each step detailed and shown. The lift links are adjusted (20:04-30:13).

The grader shown in the film was built by Westinghouse Air Brake Co (WABCO) and RG LeTourneau Inc. Le Tourrneau was bought out by WABCO in mid-1953 and not long after acquired JD Adams of Indianapolis, Indiana, which had been building graders since the 1880s and which had also invented the leaning front wheel concept, still used on motor graders today. The range consisted of the models 220, 330, 440, 550 and 660 spanning 60 to 190 horsepower. Primary production of the motor grader line was at Adams’ original Indianapolis, Indiana facility with the Adams plant at Paris, Ontario, Canada, providing overflow production. The final range of Wabco motor graders (LeTourneau-Westinghouse having officially changed its name to Wabco in 1967) included the 444, 555, 660B, 666B, 777B and 888B. WABCO ceased making motor graders in 1983.
