This color educational/training/promotional film by the Clevite Corporation, a maker of bearing parts, is about the recognition, causes, and corrective techniques taken in the replacement of engine bearings. No copyright but circa late 1950s.

Car pulls into a service station. A mechanic is under a car working on it. A customer has questions about his car and chats with the mechanic. Another car pulls in and the mechanic is under another car working on it. A customer has questions about his car and chats with the mechanic. The mechanic lays down working on a car (:10-2:06). Cars race on a freeway. Mechanics work on a car. Businessmen, a sign for the ‘Clevite Clinic.’ Different parts of an engine are shown as the men discuss them. Bearings. A customer looks over his car as the mechanic looks on. A female customer opens her hood but her engine is actually in the back, as shown to her by the mechanic. Exhaust shoots out of the exhaust pipe. Low oil pressure is pointed out by the mechanic. Men in an office discuss engine operation. A customer looks over his car as the mechanic looks on (2:07-5:06). Men talk about an engine in an office meeting. They look over bearings. Close on some bearings. Animation shows how bearings can be damaged, the narrator explains. A damaged bearing. A man drives a van. Bearings shown to a man at the meeting. Animation shows how bearings can be affected by particles. A customer has questions about his car and chats with the mechanic. Close on the air filter which is filled with dirt and dust. Two mechanics chat and smoke as they work on an engine. Three different bearings. Animation shows how a bearing can be damaged as the narrator explains what is going on with all three bearings. A mechanic plays with the bearing. Animation shows what the mechanic did that was wrong with the bearing. (5:07-9:46). Animation shows how the third bearing was damaged. Back in the office, two halves of the same bearing. Animation shows pressure areas and the bearing, the narrator explains. Another bearing, another animated explanation. Crankcase/crankshaft distortion – animation explains. A bearing needs oil (9:47-12:09). Another bearing – this one has plain normal wear. A car drives down the street. He turns into a service station and workers come over to the car. The men in the office take off their jackets and look at bearings in an actual engine. Tools are cleaned. A mechanic changes oil and checks parts. A hand holds a valve that has a number on it (12:10-14:24). A mechanic puts parts together. The engine shaft rotation. Belts move on the engine. A hand jots notes and numbers down. Oil passages are cleaned. A mechanic puts pieces together. A valve stem is held by a hand. Oil passages are cleaned. An air hose is used (14:25-16:56). The men stand around an engine. A hand wipes pieces with a cloth. Pieces are removed. Bearing clearance is checked up close. Screws are tightened up close. Crank case is placed in upside down. Camshaft bearings checked. A man leafs through a training manual. Pistons are checked. A mechanic lines up his bearings. A mechanic readies to file his bearings but he should not (16:57-21:07). An oil seal is worked on. Heavy oil coats the surfaces where the bearings will go. Mechanics place pieces where the go. A torque wrench is used. The crankshaft is checked. A hand holds a thrust main bearing. Pieces are placed into an engine (21:08-23:38). Hands place pieces in an engine. A torque wrench tightens. A mechanic checks oil pressure and for oil leaks (23:39-24:59). Factory trained mechanics leave where the engine is. The men exit a building. A customer chats with mechanic. A mechanic writes notes. (25:00-26:18). End credits (26:19-26:26).

The CLEVITE CORP. was founded in 1919 as Cleveland Graphite Bronze to make bearings and bushings for the automotive industry. Under a name derived from the graphite baked into the interior of the self-lubricating bearings used to support engine crankshafts and piston rods, Ben Hopkins began CGB operations at 2906 Chester with 20 employees. The demand for bearings followed the rise of the auto industry; by 1937 the company, then located at 8880 E. 72nd St., made 183 million parts annually and employed 2,300. This growth was due largely to the introduction of the Thinwall bearing in 1930. After many decades of growth, the company was sold and the Clevite mark disappeared in the 1980s.
