to test Toyota and Lexus trucks for the potentially catastrophic engine defect the company’s engineers have come up with “smack it with a hammer”... Everyone I knew in the Navy from 89 -99 knew that as the "bigger hammer theory of mechanics."


In this case, a tiny, plastic hammer built specifically for the purpose of creating a vibration that can be measured in a controlled environment. Pickup Truck + SUV Talk shared a fairly detailed breakdown of the procedure over the weekend. Essentially, by measuring the vibrations that move through the engine when struck by the tool, Toyota can determine the health of critical components without having to tear the engine down for a costly, time-consuming physical examination.

this inspection uses the resonant frequency of the front of the crankshaft to assess the condition of the #1 main bearing


Toyota hopes this new procedure will give them some reassurance that the process isn’t entirely arbitrary. By measuring the frequencies transmitted through the engine, Toyota can tell how much main bearing #1 has degraded. When combined with a software analysis of the truck’s service life, Toyota techs will be able to tell with a reasonable (but not 100%) degree of certainty whether a given engine is a goner.


of course, most of you are familiar with using a hammer on a crank to listen to the ringing to discover if there is a crack, (dull noise) or if a crank is "sound" (rings like a bell)

Wright 4480 3/8ths or 1/2" drive ratchet wrench, a lot like a Thorsen 77


Also known as the "pear shape" socket wrench


Inventors: Richard B. Wright (Akron, OH), Hugh T. Greenlee (Gates Mills, OH)
(if your last name is Wright, and you're from Akron Ohio, you're related to the Wright Brothers... so am I) 
And Greenlee tools are well known to be high quality, and now owned by Ridgid

The Patent was filed on June 7th, 1982 and Granted on Oct. 30th, 1984 and the assignee was the Wright Tool and Forge Company in Barberton ,Ohio

the Governor of Delaware with his '29 Studebaker President Eight, and license plate #1, on a "Weaver brake tester" that used drive-over plates and liquid gauges to instantly show each wheel's braking power simply by driving the car on at steady speed then jumping on the brake pedal. (thank you CoSC!)

CoSC left me this terrific trivia info in the comment section! 

The hierarchy in the way license plates once were allocated reflected late eighteenth century political thought in most states. New York allocated “1” to the governor and “2” to the lieutenant governor. 

State senators would also get low numbers, the state’s senior U.S. Senator, the junior U.S. Senator, and the Congressman is issued a plate also in the single digits. 

anything coveted and derived from official governmental action was leveraged into a reward for political support. So in the early part of the 20th century, that low-number license plates became a way for politicians to say “thank you” by conveying favored status to the holders of such single digit plates  Law enforcement was aware a motorist displaying a low-numbered plate was due preferential treatment.
