Achieving Critical Fastener Torque

Applying Torque to a Threaded Fastener is Merely the Act That Fulfills the Goal of Achieving Proper Clamping Force

Threaded fasteners require the proper amount of tightening in order to achieve the desired clamping force to secure components. This may involve either reaching a specified torque value or a combination of torque plus additional angle tightening. Either way, the goal is to obtain proper clamping load. With few exceptions, tightening by “feel” is simply inadequate. Under or over tightening can cause fastener failure, components cracking, allowing leaks of combustion pressure, vacuum or fluid leaks, warped components or any combination of faults. Adhering to published torque (or torque-plus-angle) specifications is important for all installation or assembly tasks, but is especially critical for engine, transmission, steering, suspension and brake system applications.

Ride Control Complaints

We Examine 5 Common Customer Issues 
Ride control complaints are one of the most common types of concerns expressed by customers. Quite often, the customer’s description is vague or misleading.  Attempt to gather as much information from them as possible prior to performing an inspection. For example,  do you only hear a “funny” noise when driving n bumpy roads or on smooth roads as well?  If you suspect that the vehicle is heavily loaded with cargo at times, ask if the “wandering” they experience only occurs when heavily loaded, etc. The customer’s descriptions of an  issue should be considered merely as a starting point. It’s up to you to inspect and road test to determine the actual cause of the complaint.

Noise Takes a Toll

How many times has someone told you to take care of your hearing?  Anyone who works in a busy shop is subjected to a range of noises every day....pneumatic wrenches and impact guns, drills, air compressors turning on, vehicle horns, vehicle alarm system screeches, hammers striking metal, etc. Some of these noises, especially repeated exposure to certain noises, can damage your hearing. We all know how important it is to wear eye protection to save your eyeballs from fluids or metal chips, and to wear reinforced work shoes to save our toes from being mashed by heavy objects and gloves to protect our skin from certain chemicals or from handling hot and/or sharp objects,  but many of us tend to ignore ear protection, often assuming that “the noise only lasts for a few seconds, so it won’t matter.”
