"A RING THAT'S RIGHT FOR EVERY ENGINE" 1974 INDY 500 AUTO RACE PERFECT CIRCLE PISTON RINGS 14754

A Ring That’s Right For Every Engine is a 1970s promotional film for Perfect Circle’s piston rings (Dana Corporation). The short film opens with footage of racecars on the track at the 1974 Indianapolis 500. Lloyd Ruby pulls up in his No. 9 car. He speaks to the camera about racing. There are a few shots of pit crews working on engines. Ruby talks about his reliance on Perfect Circle piston rings. The film shows a number of different vehicles that apparently use/used Perfect Circle products: 1926 Indianapolis 500 winner Frank Lockhart smiles for the camera (02:16); a Packard motor car is driven on a road; World War II trucks and tanks drive in the field; tractors work on a job (02:55). Ruby gets out of a car at Perfect Circle’s Rushville, IN plant (03:44), where he takes viewers on a tour of the plant. A man creates casting molds for the rings. Molten metal is poured into the molds. At the Hagerstown chemical factory (05:11), scientists develop new products. A woman operates a spectrograph. Back at the Rushville plant, an employee strips rings away from the mold core (05:58). Castings are tumbled, and then run through a machine that splits the double rings into single rings (06:40). A man loads rings into a disc grinder (07:02); the sides of the rings are ground and then come off a conveyer belt. Viewers see some of the devices used to test the sizes of the manufactured piston rings (07:46). Rings are assembled on an arbor and aligned, then spun on a lathe. Finally, they are put through a milling machine (09:07). At a laboratory, instruments are used to electronically check rings as part of quality control (09:40). A new machine performs all ring machining operations for non-coated rings (10:20). Coated rings are sprayed with a plasma spray gun (11:04). The finished rings are measured electronically for plate thickness in the lab (11:44). Ruby shows off chrome and chromatic rings (12:15). Women check the rings as part of quality control (12:56), checking for any visible or physical imperfections. A machine measures the hardness of a ring (13:44). Viewers are then taken to one of Perfect Circle’s engine test laboratories (14:25), where engineers test the rings in various engines. Ruby poses in his racing suit with a box of Perfect Circle piston rings (16:37). A man demonstrates how to install a piston ring (17:12), cleaning the piston ring grooves first. Once complete, he oils the rods, pistons, and rings. A ring compressor is slid over the piston and tightened. The film ends with Ruby pulling out onto the racetrack in his no. 9 car (19:10).

A terrific chronology of the manufacturing process and testing of piston rings!

I think this is my first time seeing the late, great Lloyd Ruby of Texas do an ad for auto racing.
Lloyd was a great driver...the man who should have won an Indy 500 and a Championship of the Indy Cars U.S.A.C. sanction organization.
This is a good film on engine piston rings purpose.

Perfect Circle was a great Indiana Company that made world class products right in Indiana and used racing as a way to promote themselves. In 1963 they were bought out by Dana but continued to maintain their business for many years until Dana's bankruptcy in 2006. The Rushville plant was closed for many years and then re-opened as Intat Precision. The Hagerstown headquarters and plant is now a parts warehouse for Autocar.

They coat the rings with Molly? Cool! :{D

Maynard needs to use this whole Perfect Cricle thing in a Perfect Circle tour.
Have this playing in the background and songs that sound like they're about cars and mechanics and racing, but are really Maynard being mad at God over his mom. :{

The track featured at the beginning is the Milwaukee Mile, not Indy.

19 minutes and 52 seconds of cmmerciall for piston rings ? so when does the real video start.
